| 摘 要： | 引入地理信息系统（ＧＩＳ），应用专家打分模型，直接提取地理信息产品。以地质地貌、流域形状系数、森林覆盖率和坡耕地、荒地、暂不利用地面积比例等因子将清水河流域的１７８个小流域进行了不同层次的计算机图形叠加分类，为实现以小流域为单元的防护林体系生态效益评价和水土保持综合治理打下了基础。

| Abstract: | By applying GIS,using expert models and extracting GIS products informa-tion,178 small watersheds of the Qingshuihe watershed(the tributary of the Yellow Riverwith an area of 434km￣2)were classified into different classes by graphs overlayed with factorsof geomorphology, watershed coefficient,field proportion,wasteland proportion,useless fieldproportion,etc.This formed the basis of the benefits assessment of hydrology ecology andwatershed management in the unit of small watershed. |
