| 摘 要： | 运用GIS软件ArcGIS、Arc Hydro Tools扩展模块,以双阳河流域为例,探讨了数字高程模型(DEM)的处理及其水文模拟分析。对双阳河流域数字高程模型(DEM)进行图幅拼接、网格重分及切割等处理分析,生成双阳河流域数字高程模型。基于DEM和GIS进行流域的水文模拟分析,包括下垫面计算、水流方向计算、水量计算、流网提取,最后进行了双阳河全流域界线的划分并确定流域面积,生成了双阳河数字流域。

| Abstract: | The treatment and hydrology simulation analysis of digital elevation model(DEM) were discussed using ArcGIS software and its Arc Hydro Tools extension with an example of the Shuangyang River watershed. The digital elevation model of the Shuangyang River watershed was generated through map, grid redivision, and separation of all the DEM maps of the Shuangyang River watershed. The hydrological simulation was conducted based on DEM and GIS, for the major processes of lowland water infilling, calculation of water flow direction and water flow accumulation, and water network flow net. Finally, the digital watershed was generated through separa-tions of the whole watershed and the sub-watersheds of the Shuangyang River watershed. |
