摘　　要：结合目前开展的生态清洁小流域建设,为简便规划前期调查与图件制作的方法,探讨了一种以电子地形图、航片为数据源,结合GIS工具,快速划分地块的新方法,并在密云水库上游蛇鱼川小流域开展应用,结果表明快速地块划分方法提高了基础图件制作的准确性和工作效率,为生态清洁小流域的建设与规划提供了技术支撑,同时随着全国水土保持信息化的不断发展,将有助于推广更多的新方法与新技术应用到流域的规划与设计中。This paper introduces a simple method for planning investigation and making graph through present ecological and clean small-watersheds constructions. Taking Sheyuchuan watershed in the upper reaches of Miyun reservoir as an example and electronic topographic map, aerial photo as data sources, the quickly block division method by using GIS is discussed. The method improves accuracy and efficiency for making basic graph, and provides technical support for small-watersheds construction and planning. With the continuous development of national soil and water conservation information, it is benefit to extend new methods and technologies application.
