【摘要】 采用文献资料法和对比法从研究目的与内容、研究视角与方法等方面对国内耕地保护阈值的主要研究成果进行较为系统的总结、分析和对比。研究表明:耕地保护阈值研究的目的由土地人口承载力研究向耕地保护补偿分区等拓展,具体目的及内容趋于多样化;研究视角以粮食安全为主,少数学者选择生态安全和社会保障视角,在测算土地利用规划目标年耕地保有量时采用综合视角;研究方法及模型多样化,以最小人均耕地面积模型应用最为广泛;案例研究多针对全国及省级行政区,缺乏大经济区的案例研究。进而提出未来耕地保护阈值测算应以耕地功能识别为基础,做到"系统性"与"区域差异性"兼顾。更多还原

【Abstract】 The purpose of this study is to conduct a literature review on the threshold calculation of cultivated land in China.Methods of documentation and comparison are employed to summarize and analyze the research progresses of the topic.The results indicate:1)Objective developed from land population-supporting capacity study to cultivated land protection compensation zoning,research purpose and content are becoming diversified.2)Many threshold calculations are studied form perspective of food security,few scholars consider it from perspective of ecological or social security,and comprehensive view is adopted in land use planning.3)Methods and models have become diversified,and the model of "minimum area per capita of cultivated land" is used more widely.4)Cases are mainly for the nation or some provinces,lack of study on big economic zones.It is concluded that threshold calculation should be based on function identification of cultivated land,systematic and regional analysis approach should be used too.更多还原
