| 摘 要： | 为了检验航天飞机雷达地形测绘使命(SRTM)生产的数字高程数据在地表水文模拟分析中的应用效果,以贵州省内清水江流域为例,利用ArcHydroTools以CGIAR.CSI SRTM 90m数据和国家基础地理信息系统1:400万数字水系图为数据源,进行了流域地表水文模拟.分析结果表明:以CGIAR-CSI SRTM 90 m数据为基础提取的数字河网的空间分布与实际情况十分接近,提取的数字流域界线与水文部门基本相符,说明CGIAR-CSI SRTM90 m数据在数字地形分析的诸多领域,特别是地表水文模拟分析方面必将有着十分广泛的应用前景.

| Abstract: | In order to verify the effect of applying SRTM data sets in surface water hydrologic simulation,an investigation was conducted to simulate the surface water flow at Qingshujiang watershed,Guizhou,Southwest China. In this study,Arc Hydro Tools was used to extract watershed characteristics,and also an ArcGIS interface was developed. Using the tool set,the river network and subwatersheds of main tributaries were delineated from CGIAR-CSI SRTM 90 m DEM. By comparing the river network delineated from CGIAR-CSI S... |
