摘  要:
对玛曲高寒草原风沙危害的类型、危害程度和治理技术模式进行了调查研究。认为玛曲高寒草原风沙危害主要有:导致土壤肥力降低、草原生产能力下降、草原生物多样性降低、对当地居民生活和家畜危害、增加黄河泥沙量等五个方面。针对不同类型沙化草原和危害方式提出了具体的治理技术模式,包括流沙治理的"封育+固沙+人工补播"模式,孤立沙丘全覆盖治理模式,中度沙化草原治理的"封育+人工补播(补植)+清除毒杂草",潜在沙化草原防治模式等和毒杂草治理技术,护岸林营造技术等。

摘  要:
Study was conducted on type of wind-sand damage,damage degree and control technology model of alpine grassland of Maqu.Wind-sand damage of alpine grassland of Maqu was mainly as follows: soil fertility decreased,production capacity of grassland decreased,grassland biodiversity reduced,local residents life and livestock were damaged,and quantity of sediment of the Yellow River increased.Concrete control technology models were proposed in this paper according to different type of wind-sand damage and damage model.They were "Fencing+ sand fixation+ manual reseeding" model of shifting sand control,complete coverage control model for isolated dune,"Fencing+ manual reseeding(repair planting) + cleaning poisonous weeds" model of moderate desertification grassland control,potential desertification grassland prevention model,and poisonous weeds control technology and planting technology of bank protection forest,etc.
