| 摘 要： | 本文以黄河无定河水系岔巴沟流域为例，针对其气候、植被以及下垫面条件等时空变化特征，在全流域1∶1万DEM基础上，建立了具有物理基础的分布式流域水文模型，模型由网格单元的超渗产流模型和汇流模型组成，提出了考虑流域水保措施的流域汇流计算。使用该模型对1970～1989年大中场次洪水进行模拟计算，结果表明：计算值与实测值基本吻合。

| Abstract: | The Chabagou basin, located in an area with high and coarse sediment yield, was selected as the test area to study the distributed hydrological model according to the local climate, vegetation and ground characteristic on each grid. The model was combined with digital runoff yield model and digital watershed flow concentration model. Excess runoff mode has been applied in runoff yield model and digital method in watershed flow concentration. Lagging effect is observed by area-time method and concentration attenuation by linear-reservoir. According to the flood event simulation from 1970 to 1989, results are rather satisfactory. |
