摘　　要：利用重庆市1996-2005年的社会经济统计资料和土地利用变更调查数据,分析了重庆市直辖十年来耕地动态变化,通过主成分分析法进一步探讨了影响耕地动态变化的驱动因子。结果表明:10年来,重庆市耕地面积总体呈减少趋势,2001年后,耕地占用的速率明显加快。其中经济发展、产业结构调整、人口增加、生态退耕政策等构成了耕地数量变化的主要驱动因子。According to statistical and survey data from 1996 to 2005, quantitative dynamic changes of cultivated land in Chongqing City during the last 10 years are discussed. By using the principal component analysis, the mechanism of driving forces for these changes are analyzed. The result indicates a general decreasing trend of the area of cultivated land during the past 10 years and an increasing rate of conversion cultivated land to other land uses since 2001. The driving forces of cultivated land change are mainly economic development, re-adjustment of agricultural production structure, population growth, the present policy of returning farmland to forests.
