摘　　要：洪水动态演进模拟会对洪水灾害应急提供重要依据。随着遥感信息的迅猛发展,利用其实现实时的洪水淹没范围动态监测已逐步可行。采用基于下垫面阻力的洪水演进模型和开放式洪水演进模型对汶川县境内岷江中上游区域进行反演。针对不同的地形,模拟了从零维到二维的水流状态,具有较好的动态演进监测效果。The dynamic simulation of floods would provide an important basis for flood disaster emergency. With the rapid development of the remote sensing information,the use of real-time flood flooding range of dynamic monitoring had been gradually feasible. In the paper,a flood routing model based on the underlying surface resistance and an open flood routing model were used to retrieve the upper and middle reaches of Minjiang River in Wenchuan county. For the different terrain,the flow state from zero dimension to two dimensions was simulated,and the dynamic monitoring was better.
