乡村劳动力结构变动对耕地利用转型的影响机制研究：以湖南省为例

劳动力是农业生产的基本要素，但随着我国城镇化进程的持续推进农业劳动力供给面临数量减少和质量不高的双重困境，深刻改变着农业生产与耕地利用方式，基于劳动力结构变动视角研究城镇化进程中耕地利用转型及其调控途径具有重要的现实意义。本项目以人地关系地域系统理论为指导，基于“理论框架-实证分析-优化调控”研究主线，集成Arcgis空间分析、质性分析、数学模型和抽样调查方法，重点研究湖南省城镇化进程中乡村劳动力和耕地利用转型过程及其动态格局；厘清劳动力结构变化对耕地利用转型的影响。基于典型区调查，从家庭农户尺度揭示城镇化进程中劳动力结构变化对耕地利用转型的作用机理，从社区和农户尺度提出劳动力结构变动下耕地利用转型的优化调控策略。项目突出城镇化进程中乡村劳动力结构对耕地利用转型影响的演变规律、区域差异、机理解释和科学调控的系统性研究，可为制定适宜的土地利用政策并推进实施乡村振兴战略提供科学依据。

Labor force is the basic element of agricultural production. However, with the acceleration of China’s urbanization, the supply of agricultural labor force is facing the dual dilemma of reduced quantity and low quality, which deeply changes the ways of agricultural production and farmland use. Thereby, it is of vital significance to study the transition of farmland and its regulation path in the process of urbanization from the perspective of labor changes. With the human-earth areal system as the theoretical basis, and "theoretical framework, empirical analysis, optimization and regulation" as the main research line, this project integrates Arcgis spatial analysis, qualitative analysis, mathematical model and sampling survey to focus on studying the rural labor force and farmland land use transition process and its dynamic patterns in Hunan’s urbanization process. Specifically, the impact of the labor force structural changes on the farmland use transition are clarified. Meanwhile, a survey is carried out of typical areas to reveal the functioning mechanism of the labor force structural changes on the farmland land use transition from the dimension of family agricultural households. Additionally, optimization and regulation strategies for the farmland land use transition are puts forward from the dimension of communities and agricultural households to cope with the labor force structural changes. This project highlights a systematic research into the evolution rule, regional differences, mechanism interpretation and scientific regulation of the impact of the rural labor structure on the farmland land use transition, and can provide scientific bases for the formulation of reasonable land use policies and the implementation of rural revitalization strategies.
