摘　　要：地理国情普查成果的应用是地理国情普查的重要任务之一。本文以东莞市1999、2003、2008年以及2013年的地理国情普查数据为基础,利用土地利用动态度、土地利用程度综合指数等模型,对东莞市建成区14年间的土地利用动态变化进行分析。研究结果表明:1999~2013年间东莞市农业生产用地和生态用地面积大量减少,城乡建设用地面积大幅增加,以耕地和构筑物的面积变化最为活跃,研究后期土地利用动态度呈现减缓趋势;1999、2003、2008年以及2013年东莞市建成区内土地利用程度综合指数分别为:309.23、332.39、350.15、357.94。土地利用总体处于发展阶段。The application of the results of National Geographical Conditions Census is one of the important tasks.Using the models of the land-use dynamic degree, the comprehensive index of land-use degree, this article analyzed the land-use change of Dongguan city during the 14 years on the basis of the data of National Geographical Conditions Census in 1999,2003,2008 and 2013.The findings indicate： agriculture production land and ecological land area largely decreased;rural-urban construction land area has been showing growth;the change in cultivated land and structures was the biggest;the dynamic degree of land use showed a trend of slowing down in the late stage of study between 1999 and 2013;in 1999, 2003, 2008 and 2013, the comprehensive index of land-use degree were 309.23, 332.39, 350.15, 357.94 in Dongguan city, respectively, which showed that land-use was in the stage of development.
