| 摘 要： | 以土地利用数据和数字高程模型(DEM)为基础,运用GIS对空间数据和属性数据的管理和分析功能,用高程、坡度、坡向3个地形因子分析了1990年与2005年北京门头沟地区的土地覆盖现状以及土地利用动态变化度。结果表明,地形因子对土地利用类型的分布规律有明显的影响,研究区在最近的15 a农业用地减少,城镇建设用地大幅度增加,社会经济和政治因素对土地利用/覆盖动态变化的驱动作用显著。

| Abstract: | This paper analyzed the land cover and land use dynamic change from 1990 to 2005 in Mentougou district,Beijing city,use the data management and analysis function of GIS software,based on the digital elevation model(DEM) and land use data.Take elevation,slope and aspect as topographical factors to analyze the relationship between topographic and land cover.The result indicated that,landform factors influence land cover and its distribution obviously,cropland reduced and constructive land increased greatly during the recent 15 years in study area,the dynamic changes of land use caused by social economy and policies remarkably. |
