摘　　要：以磨盘山水库为研究对象,选用ASTER GDEM数据作为基础数据,应用Arc GIS软件水文分析模块(Hydrology),计算获得研究区河网、子流域范围等流域水文特征信息。并在分析基础上,依据国家水源保护区划分方法划分研究区三级保护区。将为哈尔滨市水源区保护工作提供技术支撑。Taking mopanshan reservoir as the research object, ASTER GDEM data was chosen as basic data, using Hydrology analysis module in the software of Arc GIS, river network、range of subwatershed and other watershed hydrological characteristic information of research area were obtained by calculating. Based on analysis, the three-grade protection zones were delineated according to the division method of national water source protection area. The results would provide technical support for water source protection work of Harbin City.
