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。
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.
