摘　　要：大宁河是三峡的一级支流,径流可迅速汇入三峡水库,其降雨径流模拟需要在较短计算时间内达到足够精度。鉴于此,本文分别采用SWMM和TANK模型来模拟大宁河地表径流过程和地下径流过程。模拟结果表明,该方法能够达到较好的精度,且使地表径流过程的模拟参数具有一定的物理定义,其经验可为缺乏地下资料流域的产汇流模拟提供借鉴。Daning River is the first tributary of the Three Gorges,and its runoff can quickly flow into the Three Gorges Reservoir,so its rainfall-runoff simulation needs to achieve sufficient accuracy in a short calculation time.In view of this,SWMM and TANK models are used to simulate the surface runoff process and underground runoff process of Daning River.The simulation results show that this method can achieve better accuracy,and make the simulation parameters of surface runoff process have a certain physical definition.Its experience can provide reference for runoff generation and confluence simulation in river basins lacking underground data.
