| 摘 要： | 数字高程模型是地理信息系统进行地形分析的基础数据,利用DEM可以提取地形因子,如坡度、坡向、高程信息、体积、水系、河网密度等.地形起伏度、地表切割深度、地表粗糙度等是反映地表起伏变化和侵蚀程度的指标.本文以浙江省低丘红壤区域为研究对象,在ArcGIS的支持下,利用1:10 000地形图的矢量化等高线对研究区域内DEM的生成进行了探索,实现了研究区域内的地形三维模拟;提取了坡度、坡向、坡长等地形特征因子,利用ArcGIS表面分析模块,结合通用水土流失方程,就地形变化对土壤侵蚀的影响进行了分析,为红壤地区水土流失的综合治理提供支持.

| Abstract: | Digital Elevation Model is basic data of terrain analysis.Terrain factors such as slope,aspect,elevation,etc,can be extracted from DEM based on GIS.Surface rolling,surface incision,surface coarseness,etc,are important indexes of landscape variation and soil erosion.With support of ArcGIS,DEM was developed with 1:10000 relief map in hilly red soil region in Zhejiang province,the landscape variation in three dimension was realized.Also information of slope,aspect,gully density,etc,was extracted from DEM.Integ... |
