Livestock industry is an important industry related to national economy and people’s livelihood, is the pillar industry of agricultural and rural economy, and is a strategic industry to ensure food security and residents’ life. Inner Mongolia as China’s important natural pastures and animal husbandry base, promoted the construction of national important agricultural and livestock products production base in recent years, has become an important national “granary”,“meat warehouse”,“milk can”, and“cashmere city”. The grain production ranks sixth in the country. 1/2 of cashmere and products, 1/4 of mutton, 1/6 of milk, and 1/10 of beef in the country come from Inner Mongolia. Based on the development practice of modern livestock husbandry both domestically and internationally, this study analyzed the current situation and typical cases of livestock husbandry in Inner Mongolia, clarified the key problems faced by the development of modern livestock husbandry in Inner Mongolia, and proposed key paths for the development of modern livestock husbandry in Inner Mongolia.

The basis of rural revitalization is the revitalization of rural industries. Industrial integration is an important way to realize the revitalization of rural industries. By systematically combing the experience of the “Sixth Industry Promotion” development, it was summarized that: taking “agriculture, rural areas and farmers” as the center, making full use of regional characteristics, promoting the backward integration of the industrial chain, and leave the value of the industrial chain in the countryside. On the basis of analyzing the development reality of Yunnan Plateau characteristic agriculture, based on the development status of Yunnan Plateau characteristic agriculture and the experience of Japanese agricultural development, this study put forward measures to promote the development of Yunnan Plateau characteristic agriculture.

Comprehensively explore the spatial evolution of agricultural production carbon emissions is of significant importance for formulating rational agricultural carbon reduction policies. Using agricultural carbon emission data in Shandong Province from 2000 to 2020,this study estimated the emissions and intensities across 16 regions within the province,and investigated the regional disparities, spatial-temporal patterns, and dynamic changes in agricultural carbon emissions and intensities in Shandong Province. The research findings indicated that: （1）Overall, agricultural carbon emissions across various regions exhibited a reversed U shape trend, characterized by “rise-stable fluctuation-decline” evolution trend; （2）Agricultural production carbon emission intensities in different regions showed a trend of “stable fluctuation-continuous decline”,reaching its lowest point by 2020; （3）Over the past 20 years, regions with high and medium-high carbon emission intensities in Shandong Province have continuously evolved towards medium and low intensities, with all regions transitioning to medium intensities or lower by 2020; （4）The Moran’s I index of agricultural production carbon emission intensities across the 16 regions of Shandong Province fluctuated in an N shape, demonstrating a distinct spatial clustering characteristics. In light of these findings, an in-depth analysis of the spatial evolution trends in agricultural carbon emissions in Shandong Province was conducted, along with proposed carbon emission reduction strategies, providing theoretical references for the sustainable development of agriculture in the province.
