摘　　要：泾河流域和北洛河流域是黄河中游多沙粗沙的主要来源区域,两大流域地貌形态、气象水文都比较接近。本文选取两大流域作为研究对象,为方便研究按照流域自然形态划分区段,利用ArcGIS10.0为技术平台,提取不同区段地貌微观因子、宏观因子和水系网络等,对两流域不同区段进行横向对比,分析其中的异同,根据两流域特性结合当地实际情况提出合理的水土保持建议。Jing and North Luo river basin are the main source area with abundant and coarse sediment in the middle reaches of the Yellow River, and their river morphology and meteorological hydrology are close to each other .This paper selects two river basins as the research object , for the convenience of study .According to the basin natural configuration division and using ArcGIS 10 .0 as a technology platform , different extents geomorphic microscopic factors , macro factors and drainage network are extracted and two differ-ent sections transverse are compared to analyze the similarities and differences .Based on the two river basin features combined with lo-cal, reasonable suggestions of soil and water conservation are put forward .
