Rainfall, morphologic feature and vegetational cover are the main factors affecting regional soil erosion. The results showed the rainfall between years had a less impact on soil erosion intensity in key protection region, mainly due to higher vegetation coverage and less human activities. However, soil erosion between key control region and monitoring region was largely dominated by the rainfall, and the soil erosion intensity of the two regions is much higher than the key protection region. For the protection area and key monitoring area, there were great changes about the annual runoff intensity between years, and the annual runoff intensity between years was relatively more stable in the emphasis control area, this is because a large number of engineering measures on the slope could enhance the role of control runoff. And the same time, the runoff and sediment is the main power and carrier of soil pollutants, the soil loss intensity directly affects the pollutant loss intensity. The study indicated that the loss intensity of total phosphorus, total nitrogen and CODMn had the same trend with the runoff and soil loss intensity between years, and the three regions were in order of key protection region>key monitoring region>emphasis control region.
