| 摘 要： | 在RS和GIS的支持下，获取了滇池流域1998年、2002年及2010年的土地利用分类图，通过土地利用动态度方法，分析了流域22年间土地利用类型的数量变化。结果表明：耕地和建设用地主要沿滇池分布，林地面积所占比例较大；土地利用类型变化主要发生在耕地、未利用地、建设用地，其土地利用动态度分别为1．598％、2．698％和9．021％；人口增长和经济的快速发展是滇池流域土地利用／覆被变化的主要驱动力。

| Abstract: | With the support of RS and GIS, this paper obtained the land use classification figure of three periods in Dianchi Lake basin, by using the method of land use dynamic degree, the number of land use type change of Dianchi lake basin in 22 years were analyzed. Results showed that： Arable land and construction land mainly distributed along the Dianchi Lake, the proportion of woodland area was larger; Land use type changes occurred mainly in the land, unused land, construction land, and the land use dynamic degree were 1. 598% , 2. 698% and 9. 021% respectively; The population growth and rapid economic development were the main driving force of Dianchi Lake Basin land use/cover change. |
