摘　　要：选取秦巴山区典型的谷盆类山地城市——万源市为研究对象,运用流水地貌学的地表径流漫流模型,借助GIS空间分析技术,提取城市水系网络,应用斯特拉勒(Strahler)水系分级法则,对水系进行分级。在此基础上,明确水系保护结构,并计算水系集水区面积,运用降雨曲线数值法,确定各水系的宽度。同时,参照国内外的相关研究成果,依据各水系绿地功能,确定水系绿地宽度,并结合遥感解译出的土地覆盖情况,探寻维育水系绿地系统的措施。The typical mountain fluvial geomorphology with the city, Wanyuan city, is selected for the case study. Through using surface runoff-flow model in aid of spatial analysis in GIS, the urban streams system is picked up, and the streams are classified by means of Strahler. On these basis, the protection structure of the streams system is clarified, the catchment area of each stream is calculated, and then the width of each stream is pinpointed by using Curve Number Method. At the same time, with reference to the relational research results at home and abroad, the width of each streamside green is determined based on their functions. At the end, the measure of conserving the streamside green system is explored by differentiating and analyzing the land use from remote sensing picture.
