[Objective] To analyze the characteristics of erosive rainfall and its relationship with sediment production in order provide a basis for soil and water conservation and ecological improvement.[Methods] Based on rainfall data of Jianshan river watershed and monitoring data of runoff plot from 2014 to 2016, we selected rainfall duration, rainfall, average rainfall intensity, the maximum rainfall intensity within 30 minutes and 60 minutes to analyze rainfall events, the amount and frequency of erosive rainfall under different level of rainfall and rainfall intensity, and then we analyzed the relationships between sediment yield and various erosive rainfall indexes.[Results] ① Threes years data showed that monthly change of rainfall generally conformed to Gaussian distribution and the rainfall in research area was mainly concentrated in May, June, Junly, August, September and October. The flooding season was in September. After October, the rainfall gradually decreased. In terms of the seasonal distribution, the rainfall was mainly concentrated in summer and autumn, and wet and dry season was clear. This pattern relates to continental monsoon climate. ② The mean sediment yield of corn field and tobacco field runoff plot was significantly higher than that in secondary forest, artificial forest and shrub-grass land runoff plot. ③ Within a certain range of rainfall intensity (0~5 mm/h), the sediment yield and rainfall of secondary forest runoff plots showed a significantly positive correlation with rainfall and I₆₀, and sediment yield of tobacco field runoff plots had a significantly correlation with rainfall.[Conclusion] ① The characteristics of rainfall is coincident with continental monsoon climate, with rainfall concentrated in summer and autumn and Gaussion distribution; ② The land use with different coverage produced big differences in interceping sediment and runoff. Tillage methods and crop species also have different effects on soil loss.
