草原工程侵蚀区植被恢复模式的水土保持效应
Effects of Vegetation Restoration Models on Soil and Water Conservation in Engineering Erosion Area of Grassland
摘要
Abstract
Effects of the artificial reshaping landscape for vegetation restoration on soil and water conservation was investigated in engineer erosion areas of open coal mine dump in Inner Mongolia typical steppe.The aims of this study was to restore the damaged vegetation,and to reduce water loss and soil erosion by the combined configuration of soil and water conservation measures based on characteristics of the soil and water loss,natural climate,site conditions,and other factors.The results showed that the vegetation coverage reached to 76% and the bush survival rate was 85.4% by the vegetative restoration model of planting shrubs and grass on the dumping platform,this pattern made soil wind erosion decrease by 30%~85% compared with the others.The coverage of slope vegetation increased by 60 % by restoration models of planting shrubs and grass,and of setting ecological bag and planting grass,which were better for preventing and controlling soil and water losses,and low investment,evaluated comprehensive benefits by the Rank-sum ratio.Two models could be preferred for controlling soil and water losses in the artificial reshaping landscape.关键词
