摘　　要：对不同景观类型的径流过程进行了模拟,利用建立的水文模型,对在假设的不同景观类型情景下的研究区水文过程趋势进行了预测模拟。假设了5种不同情景下的土地利用类型,分别设置为5种不同的情景,结果表明:随着森林和草地的数量的减少,研究区域的地表径流量将有增大的趋势;流域草地和林地具有消减洪峰,涵养水源的功能。This paper simulates different types of landscape runoff process by using hydrological model, and predicts the trend of hydrological process simulation in the study area under the assumption of different types of landscape scenarios. The paper supposes five different land use scenarios which water quantity al- ways remains the same：scenario1 is that most of the land use is forest and grass;scenarios 2 is that most of the land use is forest, sparsely forest and grassland;scenarios 3 is that the real land use of the region of interest;scenarios 4 is that most of the land use is range grass,sparsely forest and grassland;and scenarios 5 is that most of the land use is range grass. The results reflect that runoff will increase with grassland and forest decreasing,and grassland and forest of watershed can drop down the flood peak and achieve self--restraint of the water.
