摘要: 为了准确刻画中国耕地功能转型路径及形成机理,构建了耕地功能转型理论框架和评价指标体系,提出了基于博弈论确定指标权重的方法,基于综合指数模型测度了2000—2020年中国省域耕地功能转型指数,并分析了中国耕地转型形成机理。结果表明,2000—2020年中国耕地社会功能先增加后降低,经济功能则先降低后增加,生态功能基本保持稳定。子功能中粮食安全保障功能和生态功能处于主要地位,欠发达地区耕地经济贡献功能较强,东北地区耕地社会功能较强。2000—2020年中国耕地功能变化发生了趋势性转折,开始沿城乡居民需求发展方向演变。从耕地转型形成机理来看,总体而言城镇化水平、经济发展质量、非农产业比重和中东西部地区差异对耕地功能转型驱动有所降低,地区经济总量对耕地功能的驱动有所增加,人口密度对耕地功能的影响力总体处于稳定状态。

Abstract: In order to accurately describe the path and formation mechanism of farmland function transformation in China, the theoretical framework and evaluation index system of farmland function transformation were established, and the method of determining index weight based on game theory was proposed. Based on the comprehensive index model, the farmland functional transformation index of China’s provinces from 2000 to 2020 was measured, and the mechanism of farmland transformation in China was analyzed. The results showed that from 2000 to 2020, the social function of cultivated land increased and then decreased, the economic function decreased and then increased, and the ecological function remained stable. Among the sub-functions, the function of food security and ecological function were in the main position, the economic contribution function of cultivated land was stronger in underdeveloped areas, and the social function of cultivated land was stronger in northeast areas. From 2000 to 2020, the change of cultivated land function in China took a turning trend and began to evolve along the development direction of urban and rural residents’ demand. On the whole, the driving force of the urbanization level, the quality of economic development, the proportion of non-agricultural industry and the difference in the central, eastern and western areas on cultivated land function transformation had reduced, the driving force of regional economic aggregate on cultivated land function had increased, and the influence of population density on cultivated land function had remained stable.
