摘要
在农地利用转型研究中引入全程耦合视角,进行空间维度的系统集成,有望能够更加确切地揭示城乡土地系统的遥相关机理。为此,本文在综述农地利用转型研究进展、揭示土地系统“遥相关”研究不足的基础上,从全程耦合框架和食物系统纽带两个方面论证理论创新的科学基础,将食物系统作为衔接城市与乡村、以及整合“流空间”与地点空间的纽带,提出“城市食物系统全程耦合下农地利用转型研究的理论框架”。本文明确了城市食物系统全程耦合下农地利用转型的概念内涵、农地利用转型解释的研究路径以及农地利用转型研究的内容体系。认为城市食物系统全程耦合下的农地利用转型是资源内禀力、要素外驱力、市场配置力和政府调控力通过城市生产要素回馈路径、城市辖区食物短缺路径和城乡居民需求驱动路径协同作用的结果。深入解析城市食物系统全程耦合下的农地利用转型需要采取地理空间网络化思维,即需要将“流空间”与地点空间整合起来,从要素供求以及环境层面连接到案例区的其他多个区域出发来解释案例区的农地利用转型。本文同时介绍了农地利用转型解释中需要关注的5种要素流效应,指出食物系统全程耦合下的农地利用转型研究应重点关注农地利用转型机制、城市食物域内农地利用形态的空间差异及演变规律、农地利用对需求变化的响应水平及影响因素、以及农地利用转型调控等方面的内容。本文有望拓展土地利用转型的研究领域,并为解决新时代的“三农”问题提供理论参考。
Introduction of the concept of metacoupling framework into the study of agricultural land use transition to carry out system integration in spatial dimensions is expected to achieve more accurate understanding on the"teleconnection"mechanism of urban-rural land systems.Therefore,on the basis of summarizing the study progress of agricultural land use transition and finding out the deficiencies in the research of land system"teleconnection",this paper demonstrates the scientific basis of the theoretical innovation from two aspects:the metacoupling framework and the linkage of food system.By taking food system as the linkage between rural and urban areas,as well as the linkage for integrating"flow space"and location space,we propose the theoretical framework for agricultural land use transition under the metacoupling framework of urban food system.This paper clarifies the concept and connotation of agricultural land use transition under the metacoupling framework of urban food system,the research path for explanation of agricultural land use transition and the content system of agricultural land use transition research.It is believed that the transition of agricultural land use under the metacoupling framework of urban food system is the results of the synergistic effects of the resource intrinsic power,the external driving force of essential factors,market allocation power and government regulatory power through the feedback path of urban production factors,the food shortage path in urban areas and the demand-driven path of urban-rural residents.In-depth analysis of agricultural land use transition under the metacoupling framework of urban food system requires adopting a geospatial network mode thinking,that is,it is necessary to integrate"flow space"and location space,making explanation of the agricultural land use transition of the case study area in connection with many other areas from the perspective of factor supply and demand and environment.This paper also introduces the five factor mobility effects that ne
