摘　　要：选取了近25年浙江省耕地面积统计数据,利用GIS技术、主成分分析,研究了浙江省近25年来耕地面积变化的总体趋势、空间差异和驱动力。结果表明:改革开放以来,浙江省耕地变化总体呈逐年下降趋势且耕地变化空间差异较大;经济增长是形成浙江省耕地数量变化的主要宏观驱动因子,耕地快速减少在发生时间上与经济发展的增长基本同步;在空间分布上具有与地区间经济发展速度和水平的差异相一致的特点。In this paper the changes of cultivated land use in Zhejiang province during recent 25 years were studied based on GIS technology by using the data of Zhejiang statistical yearbook. Applying principal components analytical method, the spatial diversity of cultivated land changes and the driving forces of cultivated land changes were analyzed quantitatively.The result shows that the quantity of cultivated land use in Zhejiang province has being decreasing from reformation and opening, and its change is different in spatial distribution.The rapid economic development is the dominant macro-driving factor for the decrease of cultivated land area.The rapid decreasing of cultivated land area is coincided in time with the increasing of economic development.And the differences in spatial distribution of the changes is roughly corresponding with the differences of speed and level of economic development among the different regions.
