文章基于2000—2012年成都市各县域的耕地变化情况，运用耕地相对变化率和洛伦兹曲线与基尼系数，对成都市县域耕地的空间变化和区域差异性进行分析。结果表明：2000—2012年成都市耕地面积变化整体呈下降趋势并具有阶段性特征；耕地相对变化率从高到低呈现出由城市中心向外围扩展的趋势；各县域耕地变化呈现出区域非均衡发展特征，而且这种非均衡性逐渐增强。该结果可在一定程度上为促进耕地资源保护提供决策参考。

Based on the cultivated land changes at county level of Chengdu in the years from 2000 to 2012 and by use of the rate of cultivated land change and the Lorenz curve and Gink coefficient,an analysis of the spatial changes and the regional differences of is made of the county-level farmland in Chengdu.The result shows that the change of cultivated land area takes a downward trend from 2000 to 2012 in Chengdu with periodic characteristics.The relative rate of cultivated land change de-scends from the center of the city to the periphery.The spatial distribution of cultivated land change was of an unbalanced re-gional trend and the degree of this unbalanced development was increasing at county level in Chengdu.To some extent,the re-search results can provide a reference for the protection of cultivated land resource.
