摘要：Taking the mining wasteland formed in Xilinguole grassland as the research object, the ecological restoration mode of the soil and water conservation on mining wasteland was studied in the grassland. A test of water and soil conservation measures was conducted according to the characteristics of soil erosion, natural climate and etc., with the purpose of quickly restoring the damaged vegetation in mining wasteland and reducing soil erosion. The results showed four ecological restoration modes were used for the restoration on the mining wasteland, including “shrub”, “shrub grass”, “ecological bag grass” and “sand barriers grass”. Two ecological restoration modes which was “shrub grass” and “sand barriers grass”, made the plant coverage reach more than 60%, the amount of wind erosion was less than 8.0 t/hm 2 , the amount of water erosion was less than 3900 t/km 2 •a, the effect of soil and water conservation and ecological restoration was better, and the cost of economic input was lower.
