摘　　要：以漳河上游流域为研究区域,基于SWAT(Soil and Water Assessment Tool)分布式水文模型评价流域土地利用/覆被变化的水文响应,在1980和2005年的土地利用数据的情境下,探讨地表径流的变化及其关键的土地利用类型。SWAT模型在漳河上游流域具有良好的适用性,模型可以较好的模拟流域内的地表径流过程;受近年城镇化的发展和退耕还林还草的政策影响,分析流域土地利用/覆被变化情况,1980年-2005年间主要的土地类型变化是耕地比重减少2.84%,草地和建设用地分别增加1.3%和1.12%;相对1980年土地利用状况,2005年土地利用状况下模型模拟地表径流增加13.3%,其中建设用地对漳河上游流域地表径流的影响最为显著。As the upstream watershed of Zhanghe River as study area,based on the evaluation of the distributed hydrological model SWAT of land use/Cover Changes in hydrological responses,in 1980 and 2005 land use data context,explored the change of the surface runoff and the influence of main land type.The SWAT model has good applicability in the upstream watershed of the Zhanghe River,model can be better simulated the process of surface runoff.By urbanization development and returning cultivated slope lands into forest and grass implications in recent years,analyze watershed land use/cover changes.By urbanization development and returning cultivated slope lands into forest and grass implications in recent years,analyze watershed land use/cover changes.Relative to land use situation in 1980,land use case model in 2005 to simulate the surface runoff increased by 13.3%.Relative to land use situation in 1980,land use case model in 2005 to simulate the surface runoff increased by 13.3%.
