摘　　要：根据湫水河流域林家坪水文站47年降水、径流、泥沙资料,利用水文法建立降雨径流模型和降雨产沙模型,在此基础上根据降雨资料建立模拟天然径流量和模拟天然输沙量序列,对因降水变化和人类活动对河川径流及输沙量的影响进行了定量分析,并根据流域内主要的人类活动类型分析了水沙变化的原因。According to the 47 years data of rainfall, runoff and sediment collected by Linjiaping Hydrologic Station in Qiushuihe River Basin, the rainfall-runoff model and rainfall sediment yield model are established by using the hydrographic method. Based on the rainfall data, the natural runoff and the natural transporting silt sequences are simulated, and made the quantitative analysis for the influences of rainfall variation and human activities to the river runoff and transporting sediment capacity, and analyzed the reasons of the water-sediment variation based on the forms of human activities.
