摘要: 用中、大流域水沙耦合模拟物理概念模型,对黄河中游两个河段流域产水、产沙变化原因进行定量分析,并将气候和人类活动引起的变化分开定量评估,且用实测资料检验定量评估的合理性。

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.
