摘  要：
应用GIS空间分析技术对澜沧江上游典型区域(兰坪县)1∶1万DEM进行了分析处理,提取了研究区有关坡度、坡向、地表起伏度等地貌特征因子,并进行了定位表达和定量统计分析,对本区域地貌特征形成了总体认知,为地质灾害防治、国土规划、耕地资源开发与保护、农业产业扶持,特别是流域内水利资源的综合开发利用提供了地理空间基础支持。

摘  要：
The GIS spatial analysis technology was used to analyze and treat the 1 ∶ 10000 DEM( Digital elevation model) of upper reaches( Lanping county) of the Lancang River,some geomorphic factors such as gradient,exposure,and surface roughness in the study area were extracted,and their locating expression and quantitative statistical analysis were conducted. The overall cognition of the geomorphological features in this area was formed,which can provide geospatial support for the prevention and control of geological disasters,the planning of land,the development and protection of cultivated land resources,the support of agricultural industries,especially the comprehensive exploitation and utilization of water resources in this basin.
