Abstract
Based on the precipitation, runoff and sediment data from 1956 to 2011, the variation trend of the runoff and sediment by using the Mann-Kendall method and sliding t-test is analyzed to look for the abrupt change points. The double mass curve is also used to calculate the influence of rainfall and human activities on the runoff and sediment decline. The abrupt variations results show that the annual runoffs and annual sediments at Gaojiachuan Station show a trend of decline. The runoff series changed abruptly in 1976, and the sediments series changed abruptly in 1996. The runoff and sediment decline was mainly affected by human activities. The contribution rates of human activities to the runoff and sediment were 35.94% and 86.42% respectively.
