摘　　要：针对北京市温榆河上游流域的下垫面条件,采用数学物理方程,建立了机理性的分布式水文模型WDHM,描述次降雨条件下的植被截留、土壤入渗、地表产汇流及河道汇流等水文过程,并用1998年和2000年的2场较大洪水进行了模型的参数率定和检验。Based on the underlying surface condition in the upper basin of Wenyuhe River in Beijing, this paper sets up a physically-based distributed hydrological model, WDHM, which simulates the canopy interception, soil infiltration, overland flow and channel flow during an event of rainfall by using mathematic and physical equations. And the data of two relatively heavy floods occurring in 1998 and 2000 are used for the model calibration and validation respectively.
