摘要
流域径流模拟通常要涉及流域地形、土壤类型、土地利用等地理参数,对于小流域可以假定其地理参数变化不大,全流域采用均一参数,而对于大流域采用均一参数则不能准确反映流域的地理特性。本文以渭河流域陕西片为计算实例,应用地理信息系统(G IS)分析流域地理参数,计算流域径流量。
The watershed runoff simulation, was concerned with the topograph soil type, and land use of the basin as usual. The unified parameters can be assumed to the whole area of the small scale basin, but it can not reflect the geographic identity by that way for the variety of the real situation of the big scale basin. In this paper, the Weihe River Basin in Shaanxi Province as a case, using the GIS to analyze the geographical parameters, the runoff discharge in river basin have been calculated.
