| Abstract: | In this paper, classified quantitative analysis of changed runoff and sediment yields caused by changing climatic conditions and human activities within a basin was done by making use of physical conceptual model. It has been tested if it is efficient and rational for the flow sediment coupled simulation model for middle large scale basin introduced in literature to apply to simulate flow sediment of Jingcun basin and Hekou Longmen interarea, and the results were satisfactory. Quantitative analysis periods were divided according to the effects of changing human activities on basin flow sediment yields. Methods of classified quantitative analysis were proposed, and quantities of changed flow sediment yields caused by changing climatic conditions and human activities were analysiszed for various periods. |
