摘　　要：针对平原区下垫面多样变化和在分区内分布不均匀的特点,将平原区分解为水面、水田、旱地与城镇建设用地4种下垫面,分别采用不同的产流模型,根据圩区内外不同的汇流特性,分别采用不同的汇流处理模式.以太湖流域为试验区进行检验,结果表明了该模拟方法的可行性和有效性.Based on the complex variation of underlying surfaces and non-uniform distribution of sub-areas in plain area, the area was classified into 4 kinds of underlying surfaces, i.e. the water surface, the paddy field, the arid land, and the land for urban construction. Then different runoff models and confluence processing patterns were adopted according to different characteristics of confluence inside and outside of polders. The feasibility and effectiveness of this simulation method were verified by case study on the test region of the Taihu Lake Basin.
