Supported by RS and GIS. The method of distributed hydrological modeling based on raster Digital Elevation Models (DEM) was applied to generate basin network, to divide subwatershed and generate basin boundary automatically.

• 在遥感、GIS技术支持下 ,应用了基于栅格的数字高程模型 (DEM)的流域水文建模方法 ,进行了流域河网的自动生成 ,子流域的自动划分以及流域边界生成研究 ,根据流域地形特征将整个流域分割成多个子流域。
