Characteristics of Soil and Water Loss Based on Runoff Plot

This paper selects Zhejiang province 5 runoff plots of rainfall, runoff and sediment loss was studied.The results showed that: (1) the annual rainfall mainly concentrated in 4-9 months, accounted for 60.7%-66.6% of the annual rainfall.(2) the annual runoff is mainly concentrated in 5-9 months, which accounts for 67.4%-76.2% of annual runoff.The amount of sediment loss is mainly concentrated in 5-9 months, which accounts for 68.3%-86.7% of the annual runoff.(3) the results show that the runoff with rainfall fluctuations and fluctuations, the loss of sediment with the flow of the fluctuations in the flow, it shows that the runoff and rainfall, sediment loss and runoff are closely related.
