摘要： 利用1978—2003年耕地及相关的统计和普查数据，定量分析探讨了皖江地区近20余年来耕地数量变化趋势及空间变化规律。在此基础上，应用主成分分析法定量诊断出影响耕地动态变化的主要驱动因子，揭示了耕地变化的驱动机制。加强耕地动态变化研究，分析耕地数量时空变化规律及驱动机制，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。

Abstract: According to the statistics and detailed-investigation data of cultivated land area from 1978 to 2003, the trend and regional difference of cultivated land change in Wanjing region are deeply discussed with the helps of GIS. Based on which, the mechanism of driving forces for change in the cultivated land areas are dealt with by Principal Component Analysis in this paper. Research on dynamic changes and regional differences and mechanism driving forces of cultivated land are important for cultivated land rational use and maintaining homeostasis of cultivated land etc.
