Abstract:: The water-sediment process in the upper reaches of the Yellow River is affected by factors such as climate and land use changes, and its distribution varies greatly between and within the year. The Daxia River Basin was selected as the study area to analyze the measured runoff and sediment transport data. The watershed distributed water and sediment model(WEP-SED model)was used to simulate the water and sediment processes, and the multi-factor attribution analysis method was used to analyze the water and sediment evolution patterns of the Daxia River Basin under changing environments. The results show that the annual runoff decline rate of the Daxia River Basin is 85 million m³/decade, and the annual sediment discharge decline rate is 662 500 t/decade; the trends are all negative and persistent; the reduction in sediment volume is 1.8 times that of runoff; the water and sediment processes in the Daxia River Basin are mainly affected by precipitation, temperature and land use changes during the flood season; the contribution rate of precipitation to the reduction of runoff and sediment is -77.0% and -90.0%, and the contribution rate of temperature is -29.7% and -16.5%, respectively, while the impact of land use change on runoff and sediment increases slightly.
