[Purpose/Significance] As China enters the threshold of an aging society, the health problem of the elderly group has become the focus of attention from all walks of life. The demand for health information among this group has increased dramatically, not only because of the physiological changes associated with aging, but also because they have high expectations of how health information can improve their quality of life. As a unique branch in the field of information behavior, the research on the health information behavior of the elderly presents specific complexity in its object, phenomenon and mechanism. The acquisition, processing and application of health information has a profound impact on the health behavior of older people, particularly the potential for inappropriate drug use and overuse of drugs, which is often closely linked to their health information behavior. Therefore, in-depth research in this area is urgent and important. [Methods/Process] Based on the topic differentiation perspective, this paper conducted a comprehensive and in-depth literature review on the occurrence mechanism, internal influencing factors (such as cognition, emotion, social support, etc.) and external environment (such as family, community, and medical system) of health information behavior of older people. This review aims to identify the status quo, hot spots and shortcomings of current research, and to provide a valuable reference frame of reference and inspirational direction for future research. [Results/Conclusions] The study found that there were significant differences between the concerns of the elderly and the young and middle-aged in health information behavior, mainly reflected in the preferences for types of health information and factors influencing health information behavior. There are also large differences between urban and rural areas, social backgrounds at different stages of development, different social characteristics (such as educational background, economic status), individual characteristics (such as age, gender, health status) and health information behaviors in different scenarios. In terms of study objects, future studies can design experiments with control groups to explore more precisely the specific differences in health information behaviors of older people at different stages of development and with different characteristics. In terms of research content, we should broaden our horizons and introduce a variety of theoretical models in combination with the trend of social development, so that the research field not only covers a wider area, but also improves the depth of research. In terms of research methods, future research should actively explore new perspectives, adopt innovative research methods, such as the survey experiment method, and try to combine modern technical means, such as big data analysis and artificial intelligence to obtain more comprehensive and accurate data resources, while exploring and developing new research methods and analysis tools to promote the continuous in-depth development of research in this field.

The global warming rate and the frequency of extreme high temperature weather are continuously increasing, which could bring catastrophic impacts to rice production. To further clarify the response mechanism of rice to high temperature, this article summarized the research progress in the direction of rice heat damage from high temperature, focused on the impact of high temperature on rice production, and deeply analyzed the physiological (photosynthetic characteristics/antioxidant system) and gene molecular mechanisms of rice’s response to high temperature. We concluded that the heat tolerance characteristics of rice were formed by the interaction between varieties and the environment. Results showed that, the photosynthetic characteristics of rice were influenced by both stomatal and non-stomatal limiting factors, and the antioxidant process was achieved by enhancing the activity of antioxidant enzymes and reducing the content of malondialdehyde; rice improved plant heat adaptability by activating the expression of key genes and stimulating the transduction of heat signals within the plant; by optimizing “Before production-During production-After production” comprehensive management and monitoring system, we could explore innovative cultivation systems, and thoroughly investigate the high temperature defense mechanisms of rice. Therefore, this study aimed to clarify the physiological and molecular mechanisms of rice in response to high temperature stress, providing a scientific reference for future heat-tolerant rice breeding work and improving rice sustainable production.

Bacillus thuringiensis (Bt) is a widely distributed Gram-positive bacterium that can produce a series of insecticidal proteins during its vegetative growth and sporulation phases. It is commonly used as a biocontrol agent in agriculture, forestry and public health practice. The Bt crops developed based on genetic engineering technology provide an efficient and environmentally friendly biological control method for agricultural pest management. However, the extensive and prolonged cultivation of Bt crops has led to the gradual development of Bt resistance in pests, which has greatly reduced the insecticidal effect of Bt proteins and the long-term benefits of Bt crops. In order to gain a deeper understanding of the relationship between the mechanism of action of Bt proteins and the occurrence of Bt resistance in insects, this paper summarized the structural and functional characteristics of various Bt toxins, and elaborated the molecular mechanism of Bt resistance in insects from three main aspects: immune system regulation, changes in toxin activation, and mutations in toxin receptor genes. In addition, two insect resistance management strategies, gene stacking and ‘high dose/shelter’ were also introduced. Finally, the future research directions of Bt crops were pointed out, including further in-depth analysis of the mode of action of Bt toxins and the mechanism of Bt resistance in insects, exploration of new Bt proteins, strengthening the popularization and publicity of Bt crops, and establishing resistance monitoring network as well as early warning system.

Saline-alkali stress is one of the abiotic stresses in the process of plant growth and development, which can cause water deficit, changes in cell membrane permeability, metabolic disorders and blockage of protein synthesis in plants, resulting in crop yield reduction or death. Finding effective methods to reduce the harm of saline-alkali stress and strategies to improve the saline tolerance of plants are of great significance to the comprehensive utilization of saline land. In this paper, the latest researches on the damage and adaptive mechanism of plants under saline-alkali stress in recent years were summarized, and the physiological and molecular mechanisms of plants responding to saline-alkali stress were summed up. Furthermore, the physiological mechanisms of plants under saline-alkali stress were analyzed, which were mainly regulated by accumulating osmotic substances, increasing the activity of antioxidant enzymes and ionic compartmentalization, etc., and the molecular mechanisms were mainly regulated by signal transduction, transcription factor regulation and the expression of plant salt-tolerance-related gene, etc. This study pointed out the trends and urgent problems in the development of plant adaptation to saline-alkali environments, with a view to providing a certain theoretical basis for the selection and cultivation of saline and alkali tolerant plants.

China faces significant challenges of large population and limited arable land resources.

The genus Polygonatum Mill, commonly referred to as "Huang Jing," are plants renowned for their medicinal and edible properties. Their active constituents, including polysaccharides, flavonoids, and saponins, exhibit notable pharmacological effects. Recent studies have predominantly centered on the extraction of saponin components from the genus Polygonatum, which are attributed with anti-fatigue, antioxidant, hypoglycemic, lipid-lowering, and immune-enhancing properties. While there has been some advancement in the structural analysis of the genus Polygonatum saponins, their biosynthetic pathways remain underexplored. The synthesis of saponins in the genus Polygonatum occurs via the mevalonic acid pathway and the 2-C-methyl-D-erythritol-4-phosphate pathway, encompassing multiple enzymatic steps. This research indicates that the genus Polygonatum saponins exert diverse biological effects, including anti-tumor, antibacterial, anti-inflammatory, antiviral, and immune regulatory activities, and hold significant potential in medicine, food, cosmetics, and other sectors. Nonetheless, current studies are limited by inadequate structural analysis, an incomplete understanding of biosynthetic pathways, and ambiguous mechanisms of pharmacological action. Future endeavors should prioritize the isolation, structural analysis, synthetic biology, and pharmacology of the genus Polygonatum saponins to advance their scientific investigation and product development, thereby laying a foundation for the creation of novel therapeutic agents.

Deoxynivalenol (DON) is a mycotoxin that is produced by various species of Fusarium and is ubiquitous in food and feed. At low concentrations, it can cause metabolic disorders in animals and humans and, at high concentrations, it can lead to pathological changes in the body. The impact of DON on human/animal health and animal productivity has thus attracted a great deal of attention around the world. DON causes severe damage to the intestine, including compromised intestinal barrier, mucosal damage, weakened immune function, and alterations in gut microbiota composition. These effects exacerbate intestinal infections and inflammation in livestock and poultry, posing adverse effects on overall health. Furthermore, research into biological methods for DON detoxification is a crucial avenue for future studies. This includes the utilization of adsorption, enzymatic degradation, and other biological approaches to mitigate DON's impact, offering new strategies for prevention and treatment of DON-induced diseases. Future research will focus on identifying highly efficient detoxifying microorganisms or enzymes to reduce DON levels in food and feed, thereby mitigating its risks to both animals and human health.

长期集约化耕作导致中国设施土壤重金属累积和面源污染风险增加的状况已引起广泛关注。该研究总结了中国设施土壤重金属累积状况及其来源，发现长期盲目投入肥料及农药是引发设施菜田土壤重金属累积问题的主要原因。目前，设施土壤重金属累积呈现出广泛性和中轻度污染特征，其中镉是主要的污染元素。遵循面源污染治理中“源头预控-过程阻断-末端修复”原则，基于国内外文献综述，该文总结归纳出适用于设施土壤重金属累积特征与污染的联合阻控技术及作用机制。首先在灌溉和肥药投入等源头环节减少重金属输入；其次在作物种植过程中，通过选用重金属低积累特性的蔬菜种类或品种，结合水肥一体化施用大分子有机水溶性肥料或叶面喷施具有阻控重金属作用的营养型阻控剂，抑制作物吸收重金属；最后在末端修复环节，利用具有多元功能的土壤改良剂或微生物菌剂进行土壤钝化修复，或采用具有超重金属富集能力且能提高设施土壤生物多样性的植物作为填闲作物，实现生物修复的目标。该联合阻控技术的原则在于协同考虑污染防治、土壤改良、减肥增效等农学和环境目标，集成土壤修复与改良、水肥一体化、填闲作物栽培等技术，并兼顾设施土壤重金属污染修复工程所面临的投入品成本较高、经济效益不明显、缺失可持续改良导致效果不稳定等问题，优推能够钝化重金属并改良土壤的多功能土壤改良剂以及具有阻控重金属吸收、提高作物抗逆性的多功能有机水溶性肥料。上述措施能解决设施土壤普遍存在的重金属累积问题，提升土壤的安全生产能力，可为设施农业可持续发展提供更有效的技术支撑。

针对现有单边制动履带车辆跟踪控制算法同周期内并行控制难、跟踪精度低、转向控制次数较多等问题，该研究以电控化改装后江苏筑水农机 3B55 型履带运输车为试验平台，开展单边制动履带车辆路径跟踪控制算法研究。通过单边制动履带车辆运动学分析，构建车辆预瞄跟踪模型，提出一种预瞄跟踪模糊控制算法，将横向偏差与航向偏差作为多输入输出模糊控制器输入参数，实现车辆同一控制周期内转向与直线行驶的并行控制。为了优化车辆路径跟踪精度与转向控制次数，提出改进麻雀搜索算法(sparrow search algorithm, SSA)的自适应前视距求解算法，考虑车辆的横向偏差和转向路径角度约束，解析较优前视距离，通过仿真和田间试验对算法进行跟踪精度与转向控制次数综合评价。仿真结果表明：基于自适应预瞄跟踪模糊控制算法跟踪多角度规划路径时，车辆转向控制次数为89次，误差面积为1.74 m2。田间作业路况下，由于试验路面起伏不平，并且随速度增加车辆跟踪精度下降，但跟踪精度及转向控制次数随前视距离的变化规律与仿真结果一致，当车辆分别以0.14、0.47和0.83 m/s跟踪路径时，自适应预瞄跟踪模糊控制算法相对于固定前视距离预瞄跟踪模糊控制算法车辆转向控制次数分别减少13.59%、9.87%和11.25%，误差面积分别减少19.93%、48.48%和54.59%，验证了算法的有效性。研究结果可为单边制动履带车辆的农机自动导航技术提供创新思路与技术支撑。

稳定性是生态系统保持或恢复自身结构和功能的能力,是维持生态系统服务功能的关键。近年来全球植被稳定性面临重大威胁,生态系统稳定性的研究逐步成为生态学的热点问题。本文综述了稳定性的定义、空间格局及其影响机制,指出了当前研究存在的问题,并对未来发展提出展望。目前研究发现,生态系统稳定性是一个多维结构,主要包括抵抗力、恢复力和时间稳定性三个方面。稳定性及其影响机制具有很强的空间异质性与尺度依赖性,主要表现为在站点尺度由生物多样性等生物因素控制,而在区域及全球尺度则由温度、降水、辐射等非生物因素控制。目前植被稳定性的研究中尚存在数据源噪声难以去除,量化方法未标准化等问题。未来稳定性的研究可逐步由站点等局部尺度向区域、大陆等全局尺度扩展,并形成标准化的稳定性评估方法。

气候变暖、降水格局变化等是气候变化的主要表现形式，也是影响土壤呼吸主要的非生物因素，探明气象条件（温度、水分）对土壤呼吸影响及作用机制是理解陆地生态系统碳循环的重要内容之一。本文对近年来国内外学者关于温度和水分对土壤呼吸的影响及机制的研究进展进行综述。结果表明，（1）气候变暖与土壤呼吸存在正反馈调节，但温度适应性削弱了二者的反馈关系。增温时长和土壤碳储量不同导致温度对土壤呼吸的影响具有时空差异。土壤呼吸对温度适应性机制主要包括土壤微生物适应性、底物消耗和土壤矿物质活化等。（2）降水对土壤呼吸的作用取决于土壤初始水分含量。当土壤含水量低于萎蔫系数时，降水不仅增加土壤含水量还可促进土壤呼吸，在土壤含水量接近田间持水量时土壤呼吸达到最大值，当土壤含水量达到饱和值时土壤呼吸又会受到抑制。水分对土壤呼吸影响机制主要为替代效应与阻滞效应、底物供给、微生物胁迫以及根系响应等。（3）土壤呼吸与土壤温度、水分的耦合关系取决于土壤水热因子配比，当土壤温度成为胁迫因子时，降水引发的土壤水分含量升高对土壤呼吸的激发效应被低温的负面影响所抑制；当土壤水分成为胁迫因子时，气候变暖引发的土壤温度升高对土壤呼吸的促进作用被干旱的负面影响所抵消，进行土壤呼吸研究时需充分考虑土壤温度和水分的交互作用。为更全面深入地明晰陆地生态系统土壤碳排放扰动因素，未来气候变化下土壤呼吸与环境关系等相关领域研究应为重点方向，一是加强多因素交互作用对土壤呼吸影响的研究，并定量化研究土壤呼吸组分；二是持续关注土壤呼吸对土壤初始温度和温度波动的响应特征，探索生物多样性或群落结构组成对土壤呼吸的影响。

寒露风是双季晚稻抽穗扬花期间,因低温造成抽穗扬花受阻、空壳率增加的一种灾害性天气。为了解寒露风研究现状、继承和完善寒露风研究成果并加以突破提供借鉴和参考,本文通过对有关寒露风文献的分析和梳理,总结了寒露风研究的主要成果。大气环流异常是引发大范围寒露风的根本原因,地形、地貌、海拔等因素能引起小范围寒露风。寒露风对晚稻的危害主要在抽穗开花期,其次是孕穗期。寒露风指标研究大多基于田间试验、气象要素模拟试验、生产实践以及历史数据、文献的分析,应用比较广泛的指标是"寒露风等级"和"水稻冷害评估技术规范"。寒露风预报以天气学方法较为常见、数理统计法不可或缺、神经网络等新方法的运用是一种趋势。在南方双季稻区,寒露风主要出现在9月中下旬或以后,在全球气候变暖背景下,寒露风初日呈推迟趋势、天数呈减少趋势,但存在连续多年提前和天数增加的案例。单点(站)观测、3S技术是寒露风监测常用的技术。合理安排晚稻播种期、选择耐低温品种、以水调温等多技术并举,对防御寒露风有较好效果。本文还针对寒露风研究存在的指标因子不全面、指标标准不统一、预测预报和监测评估精度达不到精细化服务的需求等主要问题,展望了未来研究的主要方向:深化寒露风多因子致灾机理及多气象要素指标研究,构建指标体系;利用大数据、人工智能等新技术,强化农业气象智能化精准预报技术研究;加强气象观测、卫星遥感及作物模型等相融合的精密监测评估技术研究;重视气候变化背景下的寒露风新规律研究;开展与气候变化及农业科技进步相适应的防灾减灾技术研究。

青藏高原为全球气候变化敏感区，生态系统非常脆弱。青稞是青藏高原主要作物，对气候变化较为敏感。本文梳理了当前以及未来气候变化对青藏高原青稞生产影响的相关研究，就青藏高原农业气候资源和农业气象灾害变化以及气候变化对青稞种植制度、生育期和产量的影响进行归纳总结。已有研究结果表明，在气候变化背景下，青藏高原地区较其他地区增温显著，降水增加，日照时数减少，干旱和洪涝等农业气象灾害更加频繁；气候变化使得青稞潜在种植界限向高纬度、高海拔地区移动，可种植面积增加，生育期缩短，当前气候变化对青稞生长有利，同时品种更替和技术进一步提高了青稞产量和适应气候变化的能力，但在未来气候变化影响下，青稞生育期将继续缩短，青稞生产及藏区粮食安全面临严峻考验。现有研究存在青稞研究区域局限性，气候变化对青稞复合影响和综合风险评估研究较少等问题。未来需深入认识气候变化对青稞生产影响的机制机理，创建青稞气象灾害影响与综合风险动态评估技术体系，制定有效措施促进高原青稞生产适应气候变化，保障青藏高原青稞粮食安全。
