摘要： 三峡水库淹没区移民后撤安置,可能引起库区地表水上状态的变化,暴雨是水土流失的主要动力因素.本文分析了库区秭归一带的年降雨的时间分配,暴雨的时间与空间分布的强烈不均匀的特征;论述了有关水文要素,如流域蒸散发、土壤含水量等.最后对王家桥小流域进行了暴雨径流模拟.

关键词: 暴雨, 径流模拟

Abstract: To arrange migration froin the,ubmergible region in the Three Gorge Reservoir to themountains,it is possible to bring about changes in water and soil conditions of terrain surfacein the reservoir region.The storm is the most important dynamic factor causing erosion. The paper analysed temporal distribution of the annual precipitation in the Ziqui region,and discovered very strong variation characters in the temporal and spatial distribution ofstorms,At the same time the paper described relevant hydrological factors,such as evapo-transpiration,moisture of the soil,etc.Then the stormrunoff process in the Wangjia Bridge catchment was simulated.

Key words: Storm, Runoff process simulation
