Abstract

Based on a spatiotemporal perspective, this study evaluates the agricultural ecology and food security levels of 31 provinces in China from 2013 to 2022 using the rank-sum ratio method. It analyzes the trajectory changes through the center-of-gravity model and explores the dynamic relationship between the two with the VAR model. The results show that China's agricultural ecosystem has recovered since 2019, with a 21% increase in food security capability. Geographically, the agricultural ecology index shows higher values in the east and lower in the west, while food security levels are unevenly distribution across the country. Notably, the centers of gravity are located in Nanyang, Henan, with a northwestward shift, indicating advancements in the northwest region. The synergistic enhancement of agricultural ecology and food security has significantly improved stability and sustainability, highlighting the importance of their mutual complementarity. The conclusions drawn from this study may offer insights into promoting regional agricultural sustainability and developing effective policies.

农业生态与粮食安全是否相互促进？来自中国的证据

基于时空视角，采用秩和比法对2013 - 2022年中国31个省区的农业生态与粮食安全水平进行了评价。通过重心模型分析轨迹变化，并利用VAR模型探讨两者之间的动态关系。结果表明，自2019年以来，中国农业生态系统已经恢复，粮食安全能力提高了21%。从地理上看，农业生态指数呈现东高西低的格局，粮食安全水平在全国范围内分布不均。值得注意的是，重心位于河南南阳，并向西北方向移动，表明西北地区在推进。农业生态与粮食安全的协同提升显著提高了稳定性和可持续性，凸显了两者互补的重要性。本研究的结论可为促进区域农业可持续发展和制定有效的政策提供参考。

期刊介绍： Food and Energy Security seeks to publish high quality and high impact original research on agricultural crop and forest productivity to improve food and energy security. It actively seeks submissions from emerging countries with expanding agricultural research communities. Papers from China, other parts of Asia, India and South America are particularly welcome. The Editorial Board, headed by Editor-in-Chief Professor Martin Parry, is determined to make FES the leading publication in its sector and will be aiming for a top-ranking impact factor. Primary research articles should report hypothesis driven investigations that provide new insights into mechanisms and processes that determine productivity and properties for exploitation. Review articles are welcome but they must be critical in approach and provide particularly novel and far reaching insights. Food and Energy Security offers authors a forum for the discussion of the most important advances in this field and promotes an integrative approach of scientific disciplines. Papers must contribute substantially to the advancement of knowledge. Examples of areas covered in Food and Energy Security include: • Agronomy • Biotechnological Approaches • Breeding & Genetics • Climate Change • Quality and Composition • Food Crops and Bioenergy Feedstocks • Developmental, Physiology and Biochemistry • Functional Genomics • Molecular Biology • Pest and Disease Management • Post Harvest Biology • Soil Science • Systems Biology
