Characteristics of Soil and Water Loss in Typical Bamboo Forest

the selection of pure bamboo forest, bamboo forest, bamboo Tong Yang Yang Tong Hemerocallis mixed forest as the research object, on the surface rainfall and 3 kinds of stand in the runoff, soil loss and nutrient loss (total nitrogen and total phosphorus) were studied. The results show that:. (1) the runoff coefficient is relatively high, followed by heavy rain. 3 stands in pure bamboo forest runoff coefficient is the largest, bamboo - Yang Tong - Hemerocallis mixed forest minimum. (2) the runoff coefficient, soil loss and nutrient loss of 3 kinds of stand were basically the same, all of which showed a trend of fluctuation. (3) 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 the linear relationship between rainfall and surface runoff, surface runoff and soil loss.
