利用1988~2004年耕地及相关的统计和普查数据,应用主成分分析法诊断影响耕地动态变化的主要驱动因子,揭示了耕地变化的人文驱动机制.在此基础上,应用多元回归分析法分析耕地与驱动因子之间的综合定量规律.分析耕地的驱动机制,对今后合理利用耕地资源、控制耕地进一步减少、保持耕地动态平衡具有重要意义.
利用1988~2004年耕地及相關的統計和普查數據,應用主成分分析法診斷影響耕地動態變化的主要驅動因子,揭示瞭耕地變化的人文驅動機製.在此基礎上,應用多元迴歸分析法分析耕地與驅動因子之間的綜閤定量規律.分析耕地的驅動機製,對今後閤理利用耕地資源、控製耕地進一步減少、保持耕地動態平衡具有重要意義.

According to the statistics and detailed-investigation data of cultivated land from 1988 to 2004, the mechanism of driving forces for change in the cultivated land areas were dealt with by Principal Component Analysis, and human driving forces of cultivated land changes were revealed. Comprehensive quantitative law of cultivated land and driving forces were applied on the basis of this. Analysis of cultivated driving mechanism, which had an important significance for rational utilization of cultivated land, controlling the decreasement of cultivated land and maintaining homeostasis of cultivated land.
