Abstract Based on project region of wind power field in Bashang,the soil erosion characteristics,zoning,key protection area and vegetative restoration measures are studied.The results show that: the soil erosion of wind power field construction region is intercoupling with particularity of wind power field and characteristics of soil erosion of Bashang region.The erosion characteristics of wind power field in construction region is coexistence of wind erosion with water erosion,coexistence of point erosion with line erosion,and vegetation restoration is difficult,earthwork and waste slag are less.Soil erosion are mainly occurred in six regions which is road,fans area,working and living region,substations,overhead line area and abandoned dreg site.The erosion characteristics and controlling emphasis are different in regions.The vegetation restoration can be resumed with three kinds measures including fence closing,using of soil seed bank to restoration natural plant,and constructing artificial vegetation in wind power field construction area of Bashang region.
