In this study, the typical economic forests ( Phyllostachys pubescens and Myrica rubra forests) in Yuyao City, Zhejiang Province, were taken as research objects. Rainfall, runoff and soil loss data were collected from runoff plots with different measures. The differences of soil and water loss in different measure plots were studied by benefit analysis and regression analysis. The results showed that natural Phyllostachys pubescens and Myrica rubra forests had better soil and water conservation benefits. Human disturbance will increase the runoff by more than 19% and soil loss by more than 55%. There was a significant regression relationship between rainfall-runoff-soil loss in the two forest lands, but the regression curve type was affected by vegetation structure and soil properties.
