| 摘 要： | 径流模拟通常基于流域地形、土地利用、土壤类型等信息数据,以及水文气象资料。以渭河流域陕西片为计算实例,分析了流域地形、土壤类型、土地利用、前期土壤湿润程度等地理信息参数,按照地理信息层叠加方法划分径流模拟计算单元,应用SCS模型模拟径流过程。同时,结合降雨特性及主要降雨形式分析,给出降雨量与径流量的相关关系。结果表明:径流模拟值与实测径流趋势具有较好的一致性,说明模型确定的地理参数较为合理,可以应用于关中平原典型流域的径流模拟。

| Abstract: | The surface runoff simulation is used to involve geographic information data of landform,soil type,land use,hydrology and meteorology of the basin.SCS model is applied to simulate the rainfall-runoff in Shaanxi Sub-Basin of Wei River by analyzing the geographical parameters,and the main rainfall form result in surface runoff is given.In addition,the rainfall-runoff relation is also analyzed and the form of rainfall being capable of runoff is given.It has been showed the simulation result is coincident well with the record,and the SCS hydrological model based on geographical information is a good means to simulate runoff. |
