土地利用对流域降雨-径流关系的影响 ——SCS模型在深圳市的应用
EFFECT OF LAND USE ON THE RAINFALL-RUNOFF RELATIONSHIP IN A BASIN ——SCS MODEL APPLIED IN SHENZHEN CITY
摘要
Abstract
Taking up Shenzhen city as a case study area, SCS model isapplied to study the rainfall-runoff process of some rivers in Shenzhen city, then the effect of land use on rainfall-runoff relationship is analyzed. The main conclusions include: 1) Along with the intensity of human activities, the land use change leads to the increase of runoff. 2) The more the rainfall intensities and the antecedent moisture conditions of soil, the little the effect of land use on the runoff. 3) The spatial distribution of rainfall-runoff relationship changes following the change of land use classes, soil classes and antecedent moisture conditions. The regions with high values of CN are urban and water. The regions with low values of CN are forest, shrub and orchard, and the elevation of these regions is comparatively high.关键词
