流域结构分析在水电梯级开发规划环评中的应用

摘要

以长江右岸一级支流磨刀溪流域为研究对象，利用卫星影像和地形图为基础数据，在GIS技术支持下，进行流域结构分级，并通过对各级溪流的河流属性、空间结构、生态特征等的分析，就流域结构分析在磨刀溪水电梯级开发规划环评中的应用进行了研究。%Take Modaoxi river , a tributary of Yangtze River as a study , basin structure was classified by using satellite images and topo-graphic map as basic data and under the support of GIS technology , properties, spatial structure and ecological characteristics of all streams were analyzed , and application of stream orders analysis in EIA of hydropower station development planning was studied in this paper .
