摘　　要：将逆高斯分布汇流模型应用于由梯级水库组成的复杂流域汇流系统,根据上游水库的泄洪流量和下游水库入库流量的关系,建立逆高斯分布瞬时单位线河道汇流模型,并结合流域区间非线性汇流模型建立了多输入单输出的流域汇流模型,经在龙王山梯级水库的实际应用,取得了较好的效果.An inverse Gauss distribution(IGD) is applied to the complicated watershed composed of cascade reservoirs. Based on the relations between the volume of upper reservoir and the inflow of lower reservoir there educes an instantaneous unit hydrograph(IUH) concentration of channel model-IGD. And associated with the nonlinear concentration model of regional watershed, a concentration model with multiple input and single output is developed. An actual application of this model to the Longwangshan Cascade Reservoirs is given; and the verification results are satisfactory.
