Abstract:: Bamboo pure forest, Bamboo—Cleyera japonica mixed forest and Bamboo—Cleyera japonica—Hemerocallis mixed forest were selected in Anji County. Atmospheric precipitation, surface runoff, soil loss and nutrient loss (total nitrogen and total phosphorus) were studied. The results showed that: (1) rainfall showed a trend of fluctuations from June to October in Anji County, rainfall is 6.0~106.0 mm. According to the rainfall intensity grade, rainfall in Anji County was divided into light rain, moderate rain and heavy rain; (2) runoff coefficient corresponding to the rainstorm was relatively high, followed by heavy rain, runoff coefficient was the largest in three kinds of forest lands, Bamboo—Cleyera japonica—Hemerocallis mixed forest was minimum; (3) the trend of the runoff coefficient, soil loss and nutrient loss of 3 kinds of stands were basically same, all of which showed a trend of fluctuation, in June and August, the runoff coefficient, soil loss and nutrient loss were relatively large; (4) the regression equation of rainfall and surface runoff and the regression equation of surface runoff and soil loss were all linear regression equations, which showed that there was the linear relationship between rainfall and surface runoff, surface runoff and soil loss, respectively.
