摘  要:
以云南省元谋县为例,利用地理信息系统软件Arc GIS10.1为工具,以等高线地形图为基础数据来构建DEM,并对该地区的DEM进行坡度坡向和水文特征的提取与分析,并对坡度进行分类。研究了元谋县域内的基本地形特征如坡度、坡向,并提取了流域水系,研究结果可应用于生态恢复和防治水土流失。

摘  要:
Taking Yuanmou County in Yunnan province as an example,this paper used contour terrain images as the basic data to create digital elevation model( DEM) by the software of geographic information system( Arc GIS 10. 1),extracted and analyzed the slope,aspects and hydrographic features of DEM,meanwhile,classified the slopes in this area. This paper studied the basic terrain features about slope and aspect,and extracted the basin river system in Yuanmou County. The results could be applied to ecological restoration and controlling of soil erosion.
