Soil nutrient loss not only reduces soil productivity, but also causes non-point source pollution and accelerates the eutrophication of surface water. In order to understand the effects of slope lengths (2m, 4m), vegetation coverage ratios (15%, 30%, 45%, 60%, 90%) on the mechanisms of soil nutrient loss, the research studied the simulated rainfall experiment with the slope gradient of 20°, the rainfall intensity of 2.0 mm/min and the time of producing runoff for about 30 min. The experimental results showed that the runoff coefficient is mainly affected by vegetation coverage ratio.
