以深圳市为例，应用SCS流域水文模型对该市部分流域进行降雨-径流过程的模拟，分析了土地利用变化对流域降雨-径流关系的影响.结果表明，随着人类活动的加剧，土地利用的变化使径流量趋于增大；降雨强度越大，前期土壤湿润程度越大，土地利用变化对径流量的影响就越小.降雨-径流的空间分布随土地利用类型、土壤类型、前期土壤湿润程度而发生变化，CN值的高值区主要集中在城市用地和水体，低值区主要出现在林地、灌草地、果园等海拔相对较高的地区.

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.
