摘　　要：在GIS环境下采用美国ESRI提供的水文模块,利用美国联邦地质调查局(USGS)提供的SRTM 90m DEM原始数据.以三江平原挠力河流域为例,进行了相关的流域分析,包括水流方向模拟、河网提取、流域界线划定及子流域划分等多项内容,为三江平原挠力河流域研究提供了基础的数据平台。Adopting the hydrology module, which was provided by American ESRI , under the GIS environment, using primary SRTM 90 m Dem data from USGS, taking Naoli river basin in three rivers plains as an example, this paper carried out relevant watershed analysis, inclu- ding flow direction simulation, drainage network extraction, watershed boundary delimitation and subcatehment compartmentalization. The re sult provided a foundation data platform for the research on Naoli River basin in three rivers plains.
