沙障在流动沙丘造林中的作用机制及效益研究

Research on the Mechanism and Benefit of Sand Barrier in Afforestation of Mobile Dune

当前社会快速发展的同时,流动沙丘的治理工作也逐渐受到重视和关注。文章在不同规格沙障的种植密度下研究花捧、沙柳、梭梭等固沙植物的固沙作用,从而筛选出最优造林密度以及沙障铺设规格。最大限度地提升植株的存活率和保存率,促使植被健康成长,固定沙丘。此外,对沙障在流动沙丘造林中的作用机制及效益进行分析,通过详细了解当前沙障在流动沙丘造林中的应用现状,再提出有利于在流动沙丘造林中将沙障的作用机制以及效益全面体现出来的可行性对策。

At present, with the rapid development of society, the management of mobile sand dunes has been paid more and more attention. In this paper, the sand-fixing effects of sand-fixing plants such as Anthurium andraeanum, Salix psammophila and Haloxylon ammodendron were studied under different planting densities of sand barriers, so as to screen out the optimal afforestation density and sand barrier laying specifications.Maximize the survival rate and preservation rate of plants, promote the healthy growth of vegetation, and fix sand dunes.In addition, this paper analyzes the mechanism and benefits of sand barriers in mobile dune afforestation, and through a detailed understanding of the current application status of sand barriers in mobile dune afforestation, puts forward feasible countermeasures that are conducive to fully reflecting the mechanism and benefits of sand barriers in mobile dune afforestation.
