| 摘 要： | 利用1995年、2004年LandsetTM遥感影像提取研究区土地利用数据，通过DEM模型并提取坡度、高程因子，利用ArcGIS的叠加分析功能，获取研究区近十年来土地利用随高程和坡度的变化状况．研究结果表明：近十年来临沂市北部山区土地利用／覆被变化随坡度和高程的变化具有明显的规律，土地利用变化随着高程的增加、坡度的增大而减缓；土地利用变化主要集中在0-400m高程且坡度小于25°范围的坡地，其中以耕地和林地的转化最为剧烈．

| Abstract: | The research of changes of land-use is one of the hot topics of global environmental change. TM image are used to create the spatial distribution of land-use by user-computer interactive interpreting method. Under the support of GIS technologies, the study show that the land-use changes slowly with the increase in elevation and slope, the changes are mainly in the elevation of 0-400m and the slope of less then 25°, the changes between land-uses are dramatic mainly on the elevation of 0-400m, and the conversion of farmland and woodland is the most intense. |
