基于“三维”视角的国内耕地利用与保护研究述评

分析和评述了国内耕地利用与保护的研究动态,对今后的研究方向进行了展望。国内有关耕地利用与保护的研究经历了研究背景由耕地无保护向耕地严格保护过渡,研究方法由定性为主向定量和计量为主转变,空间落点由东部经济发达地区向城镇化速度快、耕地资源禀赋条件好的中部地区转移。在某一研究论题断面上,东、中部地区始终先于西部地区。得出以下结论:经济、社会因子与耕地数量保护之间的作用机制研究已近饱和;耕地质量变动对耕地利用与地区生态环境演变的响应机制探讨亟待深入;我国应开展广义的耕地保护,走"目标多样化、政策多样化、途径多样化"的可持续耕地保护之路。

Review on Cultivated Land Use and Protection Based on Three-Dimensional Perspective

Rapid progress and prospect has made in cultivated land use and protection in China.With the passage of time,the study has gone through the transition of no-protection of cultivated land to strict-protection in research background,the change of qualitative analysis to quantitative analysis in research method,and the space-shifting of eastern developed area to the middle area which has the high speed of urbanization and the superior resource endowment.Meanwhile,the eastern and middle area were ahead of western area in study on the same topic.The study shows that:1) The research which has explored the impacts of economic and social factors on quantity protection of cultivated land is maturity;2) The study will be made deeply concerning the change of cultivated land′s quality response to cultivated land use and the evolution of ecological environment;3) It is suggested for developing general protection of cultivated land and sustainable protection which has diversified goals and policies and ways as well in China.
