耕地集约利用与经济发展的耦合关系

摘要

The purpose of this paper is to explore the coupling relationship between intensive use of cultivated land and economic development. Method of the coupling model was used based on the systematic science theory. The results indicated that（ 1 ） economic development was the necessary but not sufficient condition for the improvement of intensive use of cultivated land;（2） The changing rate of the intensity level was less than the rate of economic growth; （3） The coupling degree between intensive use of cultivated land and economic development had experienced two stages, i.e., the uncoordinated stage and the ultimate development stage, between 1991 and 2009. It was concluded that the agricultural policy should be further reformed to guide a reasonable input of cultivated land, and to adjust into a more intensive use of cultivated land appropriately, which were helpful for ensuring national food security and agricultural sustainable development.%研究目的：揭示耕地集约利用与经济发展的耦合关系。研究方法：本文运用系统科学理论建立耕地集约利用和经济发展的耦合模型，对全国1991年至2009年的耕地利用集约程度和经济发展的耦合关系进行研究。研究结果：（1）经济发展是耕地集约利用程度提高的必要条件，但非充分条件；（2）耕地集约利用程度的变化速度小于经济发展速度；（3）耕地集约利用和经济发展耦合度经历了不协调发展阶段和极限发展阶段。研究结论：应进一步完善有关农业政策，引导农民进行合理的农地投入，适度提高耕地利用集约度，保障国家粮食安全和农业可持续发展。
