耕地是农业生产的重要基础，对国家粮食安全和长期稳定具有重大影响。江苏省城镇化发展水平较高，人口规模基数较大且持续增长，耕地利用矛盾突出，出现土地资源不可持续利用危机。为实现耕地资源的持续利用，针对江苏省耕地多功能协同发展问题进行研究。论文梳理了耕地多功能相关理论，阐述其内涵，通过空间数据可视化、数据分析等技术手段，选取江苏省60个区县作为基本研究单元，分析了2010-2020年耕地多功能时空演变特征，研究了耕地多功能的影响因子以及多功能间权衡与协同关系判定。最后根据外部性理论，分析耕地利用相关主体行为，结合前述分析基础，提出实现江苏省耕地多功能协同发展的实施路径。通过本文研究，得出如下结论：

1. 耕地经济和社会功能值高的地区位于江苏省北部，耕地生态功能值呈现北低南高的格局；（2）城镇化和经济发展对于耕地的经济和社会功能主要产生抑制作用，经济发展对于耕地生态功能起到促进和抑制作用，自然环境对于耕地经济功能起到促进和抑制作用；（3）经济功能与生态功能、社会功能与生态功能均为权衡关系，经济功能和社会功能互为协同关系。

通过本文研究，得出推动江苏省耕地多功能协同发展的路径为：（1）提升城镇化质量；（2）推动经济高质量发展；（3）提倡可持续集约化农业。

Arable land is the essential foundation of agricultural production, with significant impacts on national food security and long-term stability. Jiangsu Province has a relatively high level of urbanization development, a large and continuously growing population base, prominent contradictions in arable land utilization, and a crisis of unsustainable land resource utilization. In order to achieve the sustainable utilization of arable land resources, this article, based on the goals of sustainable arable land utilization and coordinated development, conducts research from the perspective of regional arable land functional changes, focusing on the evolutionary characteristics of multi-functional arable land in Jiangsu Province and the path of coordinated development. The paper reviews the relevant theories of multi-functional arable land, elaborates on their connotations, and, through spatial data visualization, data analysis, and other technical means, selects 60 research units in Jiangsu Province at the county level to analyze the characteristics of the evolution of multi-functional arable land during the period of 2010-2020, the influencing factors and mechanisms of multi-functionality, and the spatial-temporal correlation characteristics of multi-functionality balance and coordination. Finally, based on the theory of externalities, the paper analyzes the behavior of relevant subjects in arable land utilization, and, combined with the previous analysis, proposes an implementation path to achieve the coordinated development of multi-functional arable land in Jiangsu Province. Through this study, the following conclusions are drawn:

(1) The regions with high economic and social value of arable land are located in the northern part of Jiangsu Province, showing a pattern of low economic value and high ecological value of arable land from north to south; (2) Urbanization and economic development mainly have a restraining effect on the economic and social functions of arable land, while economic development plays a role in promoting and restraining the ecological functions of arable land, and the natural environment plays a role in promoting and restraining the economic functions of arable land; (3) The economic function, ecological function, and social function of arable land are all in a balanced relationship, with economic function and social function in a synergistic relationship.

Through this study, the pathway to promote the coordinated development of multifunctional farmland in Jiangsu Province is identified as: (1) improving the quality of urbanization; (2) promoting high-quality economic development; (3) advocating for sustainable intensive agriculture.
