Abstract
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.
