本文根据荒漠化地区造成的水土流失的特点,分析荒漠化地区水土保持防治分区和防治措施体系布局的情况,结合近年来防沙治沙经验,总结荒漠化地区特有的水土保持措施,如草方格沙障、土工格栅沙障和土壤凝结剂沙障,并对其使用方法、防治特点和性能指标进行综合分析比较,以期为减少工程建设对荒漠化地区生态环境的扰动和水土保持措施的合理布设提供指导。
According to the characteristics of soil and water loss caused by desertification area, this paper analyzesthe layout of soil and water conservation zoning and prevention and control measures in desertification area. Combin-ing with the experience of sand control in recent years, this paper summarized the unique soil and water conservationmeasures in desertification area Sandstone barrier, geogrid barrier and soil coagulation sand barrier, and its use meth-ods, control characteristics and performance indicators were analyzed and compared with a view to reduce the projectto the desertification of the ecological environment of the disturbance and soil and water conservation measures rea-sonable provision of guidance.
