| 摘 要： | 受城市化、地域功能分化、生产要素优化配置和交通网络快速扩展等因素影响,区域之间资源要素的流动已成为区域可持续发展的内在需求。在这种背景下,人类与地理环境互动模式的网络化就要求地理学研究采取全程耦合范式,即将区域内部、区域与周边区域、以及非邻接区域之间的人地互动同时纳入考虑。食物系统作为衔接乡村与城市、以及产地与全球消费市场的产业链和价值链,是开展人地系统近远程耦合研究的重要切入点。基于这种认识,本文在论证理论研究内在依据及外在条件的基础上,将食物系统的构成要素与远程耦合框架相结合,建立“城市化驱动下食物系统近远程耦合的理论框架”并论述该理论框架的具体内涵。以拓展理论框架中的前沿领域为基本导向并结合国家重大战略需求,本文进一步明确了食物系统耦合研究的基本问题和4个亟待突破的优先研究方向。其中,基本问题是食物域的格局特征、时空演化及其动力机制。4个优先方向则包括：耦合社会经济文化变迁与生物地球化学循环的供应链网络人地互动研究;食物系统近远程耦合效应及其调控策略研究;基于食物系统的城乡融合与长效脱贫机制研究;以及面向公共卫生安全的食物系统跨区域、多层次治理研究。本文最后设计了食物系统耦合研究的一般技术路径,研究结果可为进一步的案例实证提供理论支撑和研究思路参考。

| Abstract: | Driven by urbanization, regional functional differentiation, optimal allocation of production factors, and rapid expansion of transportation networks, the flow of resources between regions has become a key impetus for regional sustainable development. Hence, the interaction networking between human beings and their natural environment requires a meta-coupling paradigm research from a geographic perspective, that is, to consider the human-nature interactions within the region, between the region and surrounding regions, and between non-adjacent regions simultaneously. As an industrial chain and value chain that connects rural areas and cities, as well as production areas and global consumer markets, the research on food system couplings is a good and important entry point for a better understanding the interactions and networking in the human-earth system. With this perspective in mind and aiming at demonstrating the theoretical study based on internal basis and external conditions, this paper combines the food system components with the tele-coupling framework to establish a "theoretical framework of local and tele-coupling of food systems driven by urbanization", and discusses the specific connotation of the theoretical framework. Taking the extension of the frontier fields in the theoretical framework as the basic guide and combining China's major strategic needs, the paper further identifies the basic issues for food system coupling research and four priority research directions that need to be breakthrough. Among them, the pattern characteristics, the spatio-temporal evolution and its driving mechanism of foodshed are the basic issues, while the four research priorities include: human-nature interaction research of the supply chain network coupling socio-economic and cultural changes and biogeochemical cycles; effects of the local and tele-coupling of food system and its regulatory strategies; the mechanism of urban-rural integration and long-term poverty alleviation based on food system; and cross-regional multi-level governance of food systems for public health and food security. A general technical methodology of the food system coupling research is designed at the end of the paper. The conceptual framework and methodology in this paper can provide theoretical guideline and enlightenment for further food system coupling research and other similar studies. |
