摘　　要：以黄土高原西部的高泉沟小流域为例,选择19920829号和19930720号两场降雨,利用LISEM模型进行了径流和土壤侵蚀模拟,取得了较好的效果.通过构建不同的土地利用场景,进行不同场景下径流和土壤侵蚀模拟对比以及与现状的对比表明:生态改善与土壤侵蚀为互助性提升过程.For a case study of Gaoquangou Basin, a comparison between LISEM simulation and the observed data for 19920829 and 19930720 rainfall events was made and the result suggests that LISEM can be adapted for estimating runoff production and soil erosion for the Loess Plateau and the model-estimation is even more effective for high rainfall intensity conditions. By constructing different land use scenarios and comparing the different simulated runoffs and soil erosions under different scenarios, optimal interactive processes could be fostered in which the eco-environment can be improved and soil erosion can be reduced.
