摘　　要：流域地表流出的计算是水文学的一个重要研究课题。本研究以黄土高原北部的六道沟流域为流域模型,在确定试验流域地形和土壤物理性质的基础上,利用运动波理论和拟河道网开发分布型流域的"降雨-径流"过程的数值计算方法,对观测流量数值模拟结果的分析表明,该计算方法适用于北部黄土高原的实际,研究结论为该区域的地表水资源的推求提供了一种有效的数值计算方法。Estimation of the surface runoff of a basin is one of an important study theme of hydrology. In the current study,a basin named Liudaogou which located at north Loess Plateau was chosen as a study location. Based on consideration of the actual terrain and soil physical properties,we developed a numerical calculation model by using kinematic wave theory and the hypothetical channel network for simulating the process of ＂Rainfall-Runoff＂ of a distributed-type basin. The simulated results of the observed-discharge shows this numerical calculation model is applicable to the study location. Therefore, an effective numerical calculation method for estimating the surface runoff of north Loess Plateau region was proposed.
