【摘要】 乌苏里江作为国际界河黑龙江（阿穆尔河）南岸仅次于松花江的第二大支流，其水文地理分区在两国水资源开发利用方面具有重要意义。基于乌苏里江流域地形地貌、人口密度、水文地质特征等，结合乌苏里江流域的水文数据及水文地质图，利用ArcGis软件按照地表水、地下水和行政管理三因素对流域进行水文地理区划，为研究区水资源的计算做好基础工作，同时根据区划结果可以直接反映出水文现象的总体规律。更多还原

【Abstract】 Ussuri River is the second largest tributary of the south bank of Heilongjiang River(Amur River)after Songhua River. Its hydrological and geographical division is of great significance in the development and utilization of water resources in the two countries. Based on Ussuri River basin topography, population density, hydrogeological characteristics, combined with the basin of hydrological data and hydrogeological map,using ArcGis software according to the surface water, groundwater and administrative factors of the watershed hydrological geographical regionalization, basic work for the study area calculation of water resources, at the same time according to the zoning results can directly reflect the overall law of hydrological phenomenon, provide reference for related research.更多还原
