沙棘灌丛对风滚植物有非常好的固留作用 ,可以在草原矿区排土场边坡形成大面积的风滚植物覆盖层 ,从而影响沙棘的正常生长 .但风滚植物覆盖层比人工沙棘植被有着更好的水土保持和土壤培肥效果 ,当覆盖层腐烂后 ,会出现更繁茂的植物群落 .因此 ,沙棘对风滚植物的固留可促进排土场植被恢复和水土保持 . Seabuckthorn shrubs have a very good retention effect on the wind-rolled plants, and can form large-scale wind-dried plant coverings on the dump site of the grassland mining area, thus affecting the normal growth of seabuckthorn. However, Vegetation has a better soil and water conservation and soil fertility effects, when the cover decay, there will be more lush plant communities.Therefore, seabuckthorn retention of wind and rolling plants can promote the drainage site vegetation restoration and soil and water conservation.
