【 摘 要 】

Mastering the sediment yield in the watershed was the basis for the comprehensive management planning of the basin, the prevention and control of soil erosion, the rational utilization of the water resources. Due to the simple structure of the statistical model and the convenient calculation, the statistical prediction model of sediment yield was a powerful tool for the prediction of sediment yield. Based on the measured data of the Baizhang Creek small watershed in Zhejiang province, the impact factors of sediment were systematically analyzed. And then the main factors were considered to be rainfall, runoff depth, flood peak discharge and mean rainfall intensity, which were used to established statistical model of sediment yield in rainstorm. The statistical prediction model had a certain precision.
