【 摘 要 】

This paper studied 5 runoff plots of rainfall, runoff and soil erosion in Zhejiang province, China. The results showed that: (1) Annual rainfall was mainly concentrated in 4-9 months, accounting for 61%-67% of annual rainfall.(2) Annual runoff was mainly concentrated in 5-9 months, accounting for 67%-76% of annual runoff.(3) The amount of soil erosion was mainly concentrated in 5-9 months, accounting for 68%-87% of annual runoff. (4) Soil erosion was closely related to rainfall and runoff.
