Anhui Province is one of the major grain production provinces in China. The paper reviews the history process and quantity characteristic of food output fluctuation in Anhui province and analyses rule of food output applying wave theory and grey relation theory with food production statistic data from 1978 to 2010. The results show that the food output fluctuation showed classical fluctuation, fluctuation period is short and the length is rules, fluctuation showed moderate, is a rather long period of expansion in systolic. By comparison of fluctuation of food output, the period can be divided into several stages. With grey correlation analysis of the influence factors of in Anhui province, Chemical fertilizer is the important factor of food output growth, crops disaster areas have a small impact on food output.

E-commerce poverty alleviation is an innovative poverty alleviation method which can promotes the development of impoverished areas. As the northernmost agricultural province in China, Heilongjiang Province, on the one hand, has a certain degree of rural poverty, on the other hand, the advantages of a good ecological environment and abundant resources of green agricultural products. Therefore, it is very suitable for implementing targeted poverty alleviation through E-commerce. Through a comprehensive and systematic analysis of the current situation of rural E-commerce poverty alleviation in Heilongjiang Province, it is found that there are some problems such as the “relying on others” thinking of farmers, the lack of leading talents in the E-commerce industry, the low degree of standardization of agricultural products and the relative lack of infrastructure. The study puts forward some suggestions such as improving the awareness of poor households in E-commerce poverty alleviation, cultivating leading talents in rural E-commerce, establishing well-known brands of local agricultural products and improving infrastructure for the further development of E-commerce poverty alleviation in Heilongjiang Province.

This paper analyses the present situation of information poverty alleviation based on the perspective of precise poverty. Information poverty reduction experience of We County of “Tencent” has been summarized. Then three related suggestions are given to improve the conditions of poor people.

[Purpose/Significance] With the penetrating of industrialization and "Internet plus", using ICT to satisfy the yearning of people for idyllic life has become an important direction of the modern agricultural development. As an emerging pattern of agriculture and poverty alleviation, gamification extends the using of ICT to the marketing of agricultural products, which enables users to participate in the process of farming and have fun. [Method/Process] We have a thorough knowledge of the poverty situation in S, L, H District, Yunnan Province by field investigation and second-hand cases analysis. We found the current problems of development and also a relatively advantageous infrastructure and policy foundation in impoverished areas. And we pose the idea that a model innovation in poverty alleviation is the solution to these problems based on the advantageous conditions there. [Results/Conclusions] This paper analyzes the advantages of the digital agricultural gamification mode in impoverished areas, find the potential problems, and establish the path for using agricultural gamification in poverty alleviation.

The Ecological Conservation Area (ECA) of Beijing is not only an important protective screen for the ecological safety of Beijing, but a significant foundation for local social-economic development. Its development requires balancing the relationship of ecological protection and economic development. Miyun District, located in the northeast of Beijing as an ECA, was taken for case study. In this study, farmers’ income data change from 2006 to 2018 was analyzed, and indicators of agroforestry water expenditure, the regional GDP, cultivated land area, etc., were selected to construct the evaluating system for correlation analysis and multiple linear regression analysis, aiming to explore the indicators’ impacts on farmers’ income. The results showed that the per capita income of farmers had an upward trend and was positively correlated with five indicators such as agroforestry water expenditure and regional GDP, and was negatively correlated with total agricultural machinery power consumption and other indicators. To promote the coordinated development of ecological economy in ecological conservation areas, the study puts forward some adaptive income increasing strategies, such as strengthening the infrastructure construction, increasing the investment in human capital, promoting industrial transformation and upgrading and improving the ecological compensation mechanism.

The key to agricultural and rural work is to increase farmers’ income. This paper systematically reviewed the change and source components of Guangdong farmers’ income in the past 40 years of the reform and opening up, analyzed the main problems and challenges faced by Guangdong farmers’ income increase at present and in the future, and judged future growth points and policy choices of Guangdong farmers’ income increase. Since the reform and opening up, the growth rate of farmers’ income in Guangdong has experienced five stages: rapid growth-apparent decline-recovery-downturn-sustained rapid growth. The source of farmers’ income has changed fundamentally, the wage income contribution has become the main body, the business income contribution has decreased, the transfer income has become a new bright spot, and the property income contribution is relatively low. The absolute income gap between urban and rural residents shows that the ‘scissors gap’ continues to expand. At present, there are some problems and contradictions in the income growth of Guangdong farmers, such as less property income and insufficient fairness of distribution. In the new era, it is necessary to adapt to the changes of the new normal of the economy and strive to build a long-term mechanism for the sustained and stable increase of farmers’ income, including raising farmers’ human capital, promoting the development of primary, secondary and tertiary industries in rural areas, enhancing the rural property rights system, and improving the level of rural social security.

The aim is to provide a theoretical basis for predicting the prospect of grain production, improving the efficiency of grain production and ensuring food security. Using the statistical data of Hunan Province, the grey relational analysis method was used to screen the highly relevant influencing factors and a GM (1, N) prediction model was established to predict the grain production. The most influential factors related to the grain production of Hunan in 2008-2017 are the sowing area of grain crops and the total power of agricultural machinery. The scientific and technological factors are the main factors that affect the grain production, followed by natural and social factors. In 2018-2027, the grain production of Hunan has less fluctuation, and the total power of agricultural machinery and the fiscal agricultural expenditure have a greater impact. The total power of agricultural machinery has an important influence on grain production in the past and next ten years, and it is increasingly dominant. To maintain the level of production, it is necessary to attach great importance to the level of agricultural mechanization and steadily increase the sowing area of grain crops.

In order to make grain yield stable and increase grain production in Shandong Province, influencing factors on grain yield were analyzed by gray correlation method using statistical data in Shandong Province from 1991 to 2010. The results showed that effective irrigation area was the strongest influencing factor on grain yield in Shandong Province, followed by grain yield per unit area, area of cultivated land, effective amount of agricultural fertilizer, total power of agricultural machinery, pesticide amount and rural electricity consumption. Finally, the suggestions including improving the effective irrigation area, stabilizing and improving grain yield per unit area and area of cultivated land were proposed to ensure the stable grain yield increase in Shandong Province.

By the end of 2020, absolute poverty had been eliminated across China. However, there are still some problems in the development of rural economy, especially in mountainous areas, such as the backward development concept of farmers, the single mode of production and the lack of development ideas. These problems seriously restrict the revitalization of rural economy in mountainous areas. To carry out the strategy of rural revitalization, the government and society should focus on current rural development status, find out the causes of the problems, and put forward countermeasures to build up the rural economy. Taking F county in Hebei Province as an example, combined with the rural situation of other poverty-stricken mountainous areas in Hebei Province,this paper analyzed the problems existing in the progress of rural economy, especially in the mountainous areas, and put forward corresponding suggestions.

Based on an in-depth analysis of the development process of agricultural insurance in the United States and its operating experience of agricultural income insurance, this paper concludes the reference role of the development experience of agricultural insurance in the United States to the development of agricultural insurance in Shanghai and even whole China. In addition, the paper comes up with some suggestions to improve the development of agricultural insurance in China, including: (1) enhancing the construction of laws and regulations on agricultural insurance; (2) paying attention to the regional differences in agricultural insurance demand to meet the needs of different agricultural business entities; (3) increasing publicity efforts, enhancing farmers’ awareness of insurance participation, and increasing the initiative of insurance applicants and so on; (4) strengthening the information platform construction, etc.

Innovate precise poverty alleviation work has risen to national strategy under the new normal. It is important to explore the co-existence mode of the “Green water, Green hill” and “Golden hill, Silver hill”, particularly to the poverty alleviation in western China with fragile ecology. The new combination mode of “ecological poverty alleviation” and “economic poverty alleviation” was discussed by taking the industry development of psammophyte Cerasus humilis as an example. The biggest characteristic of C. humilis is strong resistance, and significant ecological function. On the other hand, economic benefit of C. humilis is remarkable attribute to its higher comprehensive utilization of fruit, kernel, leaf, root and flower. C. humilis industry relates to food, health care products, cosmetics, medicine, tourism and other fields. Deep excavation of comprehensive value and industry development of C. humilis, is not only the growing enlarged health needs of people, but also the needs of poverty alleviation and sand industry development. The paper suggests that the “economic poverty alleviation” guided by “ecological poverty alleviation”, is the essence of precise poverty alleviation.

The grain farmers of Heilongjiang Province have made a significant contribution to national food security, but they always have been plagued by the lower income based on the survey data, this paper selects the multiple linear regression models and uses stepwise to analyze the influencing factors of grain farmers’income in Heilongjiang. The results showed that crop acreage per capita, the average amount of chemical fertilizer, state investment in agriculture, secondary or higher education accounted for an average of one hundred labor are the main factors of income of the farmers in Heilongjiang. Ultimately, the paper gave suggestions that promoting the large-scale planting, raising farmers' own quality and introducing the talents of indigenous knowledge, fighting for national agricultural policy and transferring Heilongjiang surplus labor by cross-border.

China has a large population, and food security is a major event relating to people’s livelihood. Strengthening grain yield prediction can ensure food security. Based on historical data of grain yield in Sichuan from 2001 to 2015, we adopted grey system theory and set up GM (1, 1) prediction model on the basis of the weakening buffer operator, then used four error checking methods, including residual error, grade ratiodeviation, correlation degree and posteriori error to test the reasonability and the prediction accuracy. Then we applied GM (1, 1) prediction model to predicting the grain yield in future three years. Test results indicate that the grey system theory is appropriate when it is applied to grain yield prediction and has high prediction accuracy. According to GM (1, 1) prediction model, the grain yield of the year 2016, 2017, 2018 will increase by -2.11%, -0.39% and 1.21% respectively year on year. It can be concluded that the grain yield of Sichuan will increase in fluctuation in the near future.

The 19th CPC National Congress put forward the idea of‘New Era’, in which the goal of the party and the nation is to build a moderately prosperous society in all respects. Agriculture is the basis of the national economy, vigorously developing agricultural and rural economy and striving to improve farmers'' income level are the concrete manifestations of winning the poverty alleviation battle and building a well-off society in an all-round way. Western China, as the underdeveloped region, is the focus of China’s poverty alleviation. Taking in to consideration the basic situation and characteristics of farmers’income in Gansu, we used the comparative analysis to analyze the restricting factors of farmers’ income, put forward countermeasures like comprehensive management of the ecological environment, eradicating the dual system of urban and rural areas, and optimizing the agricultural industrial structure.

To implement regional targeted poverty alleviation, based on current status of targeted poverty alleviation of Shangzhou District of Shangluo City, we used diagram and data analysis method to study issues such as land utilization in poverty areas, targeted poverty alleviation achievements, and population quality. The results show that the foundation of poverty alleviation of Shangzhou is weak and the combat against poverty is arduous, the quality of the population is relatively low and their concept is backward. Therefore, we put forward countermeasures like increasing the policy guidance from the government, promoting the scale development of industries, enhancing the diversified and integrated development of poverty alleviation industries, strengthening skills training and education for poor households, conducting the dynamic monitoring of poverty, eliminating poverty-returning from multiple-channel financing, and reinforcing the project management, aiming to help the poor households get rid of poverty, promote the all-round development of deep poverty-stricken mountainous areas and make them toward a well-off society.

The role of university library in targeted cultural poverty alleviation should be the service provider based on government’s public culture service procurement and the constructor participating in public culture services system construction within the social service scope of university library.

Accelerating the poverty-stricken areas and people to get rid of poverty and become better off is China's current major social problem and livelihood issue. Accurate poverty alleviation is the inherent requirement of poverty reduction, urban-rural integration and common prosperity. Faced with the status of differentiated poverty, Accurate poverty alleviation theory is an important mechanism and guiding ideology of the current governance of poverty in China, and also the theoretical innovation under the new situation of poverty alleviation work, which ensures the top-level design of poverty relief from the system, policy and model, and identifies the specific requirements in terms of implementation steps and working methods. Its formation is both the summary of domestic poverty alleviation experience and the reference to the foreign poverty alleviation model, which effectively ensures the goal of comprehensive poverty alleviation before 2020.

[Purpose/Significance] As the new generation of ICTs, such as 5G, big data and artificial intelligence, continues to release development effects in the construction of digital countryside, rural residents in an information disadvantaged position are likely to be excluded by a new round of ICT innovation wave and fall into a new information poverty. Therefore, sorting out the new characteristics of rural information poverty in the digital era is of great practical significance. [Method/Process] The basic information, ICT access and use, information behavior and information environment of rural residents were obtained through field investigation and in-depth interview, and the characteristics of rural information poverty in the era of digitalization & intellectualization were sorted out. [Results/Conclusions] Six new changes brought by digitalization and intelligentization to rural information practice are described. It is found that factors such as time and space energy, intellectual level, social support and individual psychological factors affect the accumulation of digital capital of rural residents. It has concluded characteristics of rural information poverty, such as invalid use of ICT equipment, a new round of digital exclusion and invalid digital feedback.

In the decisive stage of overcoming poverty, hidden and stubborn factors in poverty alleviation are the key problems that need to be solved urgently, and the elimination of deep poverty problem needs more precision and innovative motive force. Therefore, based on the theoretical framework of sports science, the paper explores the blocking pathways of poverty intergenerational transmission in the new era from the perspective of sports poverty alleviation. Using the methods of literature and logic analysis, this paper analyzes the structure, culture and mixed mechanism of poverty intergenerational transmission, and then explores the three-dimensional hidden dilemma of poverty intergenerational transmission in subject endowment, ideology and economic foundation. The paper puts forward that from the main body of poverty, ‘ambition, mind, physical health’ should be highlighted at the same time, from ideology, carrying forward the traditional national sports and adhering to cultural self-confidence should be uphold; from the economic basis, revitalizing the rural sports industry and increasing income and expanding posts should be undertaken. It provides some theoretical support for blocking the intergenerational transmission of poverty through the particularity and irreplaceable development of the poverty alleviation path.

Lvliang and Taihang, two concentrated and contiguous poverty-stricken areas in Shanxi Province, are the main targets for poverty alleviation of China. In this paper, 21 state-level special poverty-stricken counties in 4 cities of these areas were taken as the research objects. The agricultural economic data of the study areas from 2008 to 2018 were obtained from the Statistical Yearbook of Shanxi Provincial Bureau of Statistics and the Poverty Alleviation Office of the State Council. The principal component analysis method was used to evaluate the agricultural economic development, in order to explore the spatial and temporal distribution characteristics of agricultural economic development and their relationship with poverty in concentrated and contiguous poverty-stricken areas in Shanxi. The results show that there are regional differences in the agricultural economic development level between Lvliang and Taihang, and the agricultural economic development has been improved with the passage of time. However, farmers’ extensive use of backward agricultural machinery in agricultural production has reduced their enthusiasm for production, resulting in a decrease in the total agricultural output value. The application of excessive chemical fertilizer in agricultural planting has led to poor soil quality and crop yield decrease, and further aggravated poverty. Therefore, when targeted poverty alleviation is carried out in concentrated and contiguous poverty-stricken areas, it is necessary to “implement policies according to local conditions and time”, change the traditional backward agricultural production mode in these areas, and take a green, inclusive and sustainable agricultural economic development road.

Promoting female’s employment out of poverty is of great significance for enhancing female’s self-development capability and promoting sustainable development of family. In this paper, the Participatory Rural Appraisal (PRA) evaluation method and sustainable livelihood framework were used to conduct field research in southern Xinjiang, and the sample townships in Kashgar that just overcome poverty in 2020 were selected to conduct a sample survey. The article classified and identified ethnic minority female’s vulnerability and poverty from personal endowment, family characteristics and social security and then established a sustainable livelihood assets evaluation system for measuring their sustainable livelihood assets, comparatively analyzed the stability of livelihood assets difference, and then explored the benefits of flexible employment for ethnic minority women in poverty areas and their sustainable livelihood requirements. The results show that (1) personal resource endowments, family environment and social security factors could all generate vulnerability to poverty risk, but the rural female’s willingness to flexible employment is actually strong; (2) rural female’s flexible employment livelihood asset index level is generally low in the study areas, and its internal difference is large; (3) based on the asset index and vulnerability characteristics, Shache and Yecheng County could be defined as areas with fragile personal endowments and family environments; Yingjisha and Jiashi County could be defined as areas with fragile family environment and social security. Therefore, corresponding countermeasures and suggestions are proposed to optimize female livelihood assets allocation and keep sustainable development of employment out of poverty.

Farmers'' income is both a basis and a barometer of rural economic development. Agricultural management income is an important part of farmers’income. Based on the survey data of five suburban counties in Tianjin, this paper uses the regression method to analyze the main factors influencing farmers'' operating income. The results show that the sustained investment of production factors and industrial structure type have a significant positive impact on farmers’operating income, while science and technology training tend to be formalistic and have a significant negative impact on it; regional position and farmers’educational level have no significant effect on operating income; new linking modes between production and marketing do not increase the bargaining power of farmers, and show no income increasing effect. The study suggests accelerating the land transfer, implementing structural adjustment policies, strengthening scientific and technological innovation and promotion, innovating production and marketing convergence mode and etc., to promote the level of farmers'' scale management and improve agricultural management income.

In this research, based on the survey data from thirteen national-level poverty-stricken counties of Lvliang City, for the agricultural economy poverty as the point of penetration, we use the principal component analysis to evaluate the status of agricultural economy development from 2007 to 2014. We also discussed the characteristics of spatial and temporal distribution of agricultural economy development. The results showed that: in Lvliang District, agricultural machineries and chemical fertilizer were overused. This induced environmental degradation in the soil. Then the poverty in this District was aggravated. The development of agricultural economy showed a trend of increment first and then decrement at the spatial scale in this District. The small values were in the northeast and southeast of this District. The great values were in the central of this District. The status of agricultural economy development was better in the middle parts of this district. These results are wished to be referred by studies on changes of future environment quality and on development of agricultural economy at poor areas in Shanxi Province.

To improve the tourist consumption level of urban and rural areas in China, the related data from 1994 to 2013 in China Statistical Yearbook were used as the sample, and correlation analysis and regression analysis were conducted. A comparison of different effects of income level on tourism consumption between urban and rural residents was performed. The results indicated that income level was the most important factor influencing tourism consumption. The consumption level of rural residents was lower than that of urban residents, but the marginal propensity to consume was higher. The influence of causal factors was smaller for rural tourism consumption.

[Purpose/Significance] The targets and tasks for poverty alleviation in the new era have been met as scheduled, and all rural residents living under the current poverty line have been lifted out of poverty. However, information dissemination remains a weak spot. Therefore, this study explores the influencing factors of information poverty in rural areas of Guizhou Province to provide a basis for promoting the coordinated development of urban and rural information communication. [Method/Process] Based on the in-depth interviews of 87 farmers in poor rural areas in five years, this paper sorted out the interview data based on NVIVO11 software according to the grounded theory principle in qualitative research. This paper makes a qualitative analysis on the influencing factors of rural information poverty from three aspects: farmers' self-factors, information infrastructure construction factors and information acquisition content factors. [Results/Conclusions] Influencing factors lead to the farmers' weak awareness of information, information dissemination is not smooth and the content of dissemination is not complete and accurate, and the information utility is unsatisfactory.

[Purpose/Significance] Consolidating the achievements of targeted poverty alleviation and building a relative poverty reduction mechanism will be the key problem for Chinese government after 2020; information poverty alleviation is expected to play a key role in the future poverty reduction in China. [Method/Process] Based on a systematic literature review and an on-site investigation, this study made an in-depth analysis on the policy documents issued by Chinese government in past decades to shed light on the governance and intervention on information poverty. [Results/Conclusions] Although China's information poverty reduction policy has made remarkable achievements, there are still some problems, including "to pay too much attention on the information infrastructure construction instead of the how to use them", " investment, but not evaluation, is put on the top priority", "the content of information poverty reduction project remains vague", "compared to social level information resource allocation, individual level information poverty intervention is ignored", and " emphasizing too much on the coverage of information sources instead of identification of those vulnerable people in the information society". Thus, based on an analysis of logic association between information poverty and economically relative poverty, this study puts forward some policy related suggestions and potential research items for future research.

The aims of this study are to determine the causes of poverty in poor areas, find out the basic cause of poverty, avoid unreasonable poverty alleviation, make targeted poverty alleviation strategies and realize an overall well-off society in poor areas. Based on vicious circle poverty theory and economic analytic logic, taking Jiuzhaigou County as an example, the basic causes of poverty were put forward, which included diseases and disability, poor resource conditions and low education level. And countermeasures such as improving government support and insurance policy innovation, promoting infrastructure construction of production and living facilities, changing farmers’traditional ideas and strengthening farmers’vocational education were put forward.

The paper aims to eradicate poverty effectively in poverty stricken areas and meet the livelihood demands of the poverty stricken population. According to the sampling survey in Ningwu and Dai, which are located in northwestern Shanxi, the authors analyzed the livelihood characteristics and demands of the poverty stricken population. The results showed that: the livelihood of the poverty stricken population showed a certain vulnerability and uniqueness in Ningwu and Dai; the livelihood demands of the poverty stricken population were manifested in 7 aspects, including the resources and potentialities, employment and income enhancement, household participation in development, basic living standard, application of suitable technology, the level of infrastructure construction and the construction level of beautiful and livable villages. The performance of the livelihood demands of the poverty stricken population determined the corresponding countermeasures. According to the livelihood problem of the poverty stricken population, this paper constructs the research content which is the combination of endogenous development and the livelihood demands of the poverty stricken population.

To improve farmers’ non-agricultural income, solve the core problems of the Sannong issue (namely, agriculture, rural community and farmers), this paper uses VAR (vector auto regression) model to empirically explore the interaction between agricultural mechanization and farmers’ off-farm income in Heilongjiang Province. The results show that agricultural mechanization and farmers’ non-agricultural income in Heilongjiang Province are Granger causality. In addition, the development of agricultural mechanization in Heilongjiang Province has a relatively stable promoting effect on the increase of non-agricultural income, but there is a certain lag in the short term. The increase of non-agricultural income will strongly inhibit the development of agricultural mechanization, and it has not yet formed a benign interactive relationship of mutual promotion. In view of this, in order to promote the formation of a benign interactive relationship between agricultural mechanization and non-agricultural income in the province, the study puts forward some suggestions on relying on scientific and technological progress to drive the development of agricultural mechanization, upgrading the service guarantee level of agricultural machinery by improving agricultural cooperation organizations, strengthening the training of agricultural machinery skills, giving full play to the utilization efficiency of agricultural machinery, broadening farmers’ non-agricultural employment channels and increasing farmers’ non-agricultural income.

To systematically construct the overall research contexts of poverty-returning risks, the existing research literature in mainstream journals at home and abroad is sorted out by means of literature research and comparative analysis. It is found that there are difficulties as follows. Most objects of the research are poor households but it is difficult to track the change trend of the production and the life of farmers out of poverty. And it is also difficult to prevent and warn poverty in advance instead of combating poverty after the event. The research methods are mostly from single index system method or characteristic index method, which are difficult to draw on each other’s strength. Based on these, the future research contexts of the poverty-returning risks are constructed and the future research trends are summarized as (three transitions): the research focus should be changed from poverty stricken population to population out of poverty and on clarifying the poverty-returning mechanism; the research perspective should be changed from combating poverty after the event to the whole process of “before, during and after the event”; the method should be changed from single index system method or characteristic index method to the a comprehensive method combining indicator system with characteristic indexes.

Abstract: On the basis of investigation on converting farmland to forest and poverty conditions in the 31 counties of the poverty-stricken area around Beijing and Tianjin’s, the article analyzes the relationship between converting farmland to forest and poverty. The analysis result indicates that the project of converting farmland to forest does not aggravate poverty degree of the local people’s life, and not promote local economic’s development too. Finally, the article suggestes that it is needed to combine the achievement’s consolidation of converting farmland to forest with antipoverty measures, and then puts forward some relevant proposals.

Fertilizer is an important measure for sustainable development of agriculture, fertilizers role in guarding the safety of our food is put into the other factors of production are not a substitute for, grasp the stimulation effect of chemical fertilizers from the guidance of agricultural production and to determine the scientific and effective fertilization programs have important theoretical and practical significance. This paper analyzed the chemical fertilizer use and food production relationship, selected the sown area of grain crops, the total power of agricultural machinery, the effective irrigation area, the amount of chemical fertilizer and agricultural workers for China's grain yield affecting factors. By using the principal component regression C-D production function model, calculated the input of chemical fertilizer on grain output elasticity and contribution rate. The results showed that: the use of chemical fertilizer and grain yield between strong positive correlation; 1978-2010 years of fertilizer on grain yield growth elasticity value was 0.18, the contribution rate was 20.79%, chemical fertilizer on increasing grain output elasticity and contribution and the results of previous studied phase decreased slightly, per unit mass of chemical fertilizer input to bring the actual grain yield increase the quantity decreases somewhat, but chemical fertilizer input was still an important factor in the increase of grain yield.

Heilongjiang is a large commodity grain province which has made extremely remarkable contributions to national food security. In order to future validate whether grain contributions and farmers’ income in Heilongjiang is coordinated or not, this paper analyzed the data of 31 provinces and cities based on the factor analysis. The results showed that, the score of comprehensive grain production capacity of Heilongjiang was 1.68, ranking No. 3 in the country; the score of its farmers’ income was -0.92, ranking No. 26 in the country; the score gap of the two was -2.6, ranking the highest in the country. According to the study, we arrive at the conclusion that the coordination between grain production and farmers’ income in Heilongjiang is extremely terrible which is lower than the level of food sales areas and other food producing areas.

In order to assess the effects of climate change on grain production, find out the internal relations between them and guide local agricultural activities, the author analyzed the variation tendency of 3 main climatic factors (average temperature, precipitation and sunshine duration) in recent 21 years in Yibin City. The results showed that all the 3 factors had an increase tendency, and the fluctuant range of sunshine duration was comparatively small. The grey correlation analysis method was used to analyze the effects of climate change on grain yield. The results showed that the precipitation had the biggest influence on wheat yield with the correlation degree of 0.869; sunshine duration and per unit area yield had the biggest relevance with the correlation degree of 0.736. Therefore, climate change influenced grain yield significantly, especially climate yield. The results could provide basis for agricultural deployment.

The grain yield from 1999 to 2017 in Shaanxi was divided into two stages and 10 influence factors of grain yield were analyzed dynamically with grey correlation analysis method, and the data processing was realized by SAS statistical software, aiming to provide data support for improving grain productivity and enhancing grain security in Shaanxi. The results showed that the most important factor affecting the grain yield in Shaanxi was the grain planting area. The effect of effective irrigation area and rural employment on grain yield was gradually enhanced. It was imperative to reduce the amount of pesticides and fertilizers and increase their efficiency. On the macro level, natural factors were still the first to influence grain output, the impact of scientific and technological factors was increased, and the last was policy factor. The important measures to ensure food security in Shaanxi are improving the quality of cultivated land, stabilizing the sown area of grain crops, reducing the amount and increasing the efficiency of pesticides and fertilizers, and promoting green grain production.

Rice-fish farming, with small investment, quick effect, low risk and high profit, is an important means of poverty alleviation through the development of green industry. The authors analyzed rice-fish farming modes in Hunan, such as government predominance type of Chenzhou Ctiy, market-oriented type of Nanxian County, and government plus market type of Chenxi County, for poverty alleviation. It is suggested that the long-term plan, mechanism of industrialization and performance evaluation, construction of infrastructural facilities, research on policy of rice-fish farming should be enhanced for poverty alleviation through industrial development.

Grain production is an important part of the national economy, and grain yield is significant for guaranteeing grain security in China. In order to improve the scientific and accurate prediction of grain yield, based on the analysis of the existing prediction methods, the grey theory and neural network were combined organically, the main and objective factor indexes were determined from many influencing factors on grain yield by grey correlation analysis. These indexes were applied in the prediction of grain yield with the artificial neural network. The results showed that the maximum error of the artificial neural network prediction was 1.21%, the average error was 0.63%, and the prediction accuracy was relatively high. This study provides a scientific and effective forecasting method for grain yield.

Tourism industry has already demonstrated the enormous function that it is in the national economic growth gradually as getting the army trade of the tertiary industry. With the development of industrialization and urbanization process of our country, more and more persons choose the village to travel, this is the demand that people release psychological pressure and return to nature, therefore its development is unusually fast. Can bring about an advance in local economy to travel in the village, impel the national income to reallocate，adjust the local industrial structure and improve peasant's living standard，because of this, it becomes the research direction and subject of the government and scholars of travel poverty. It is mostly meaning. function and strategy of probing into poverty alleviation to scan most scholars' research results, mention some questions that should be paid attention to while developing too, but the author thinks the scholars are mostly previous problems of studying travel poverty alleviation, but has neglected one question, that is: Development of the rural travel in the anti-poverty era for the travel. After rural residents shake off poverty and set out on the road to prosperity, the development that their consumption idea will influence the village to travel directly.

The income of the fishermen, who engage in marine fishing, is changing with the condition of the marine fishery resources. Changes of fisheries resources lead to its price and cost fluctuating. It ultimately affects the income of fishermen. This paper selected Xijiagang Fishing Village in Chongming County as an example because it is a typical fishing village in Shanghai. This paper conducted a 10-year investigation, which was 2002-2011, on the economic situation of the income of fishermen. We use literature research, sample survey and apply related data analysis models to analyze fisheries economic data. This paper intended to make people have a full understanding in the economic life of fishermen, who engage in marine fishing industry in Shanghai. After analyzing the current situation of the income of fishermen in Xijiagang, we can find related economic problems. Afterwards, we raised the corresponding solutions to these problems so that the fishing village may have a better development and fishermen may lead a prosperous life with more decent income than today as well.
