摘　　要：机械沙障作为一种简易高效的物理固沙措施,可以有效降低地表风速,阻拦沙粒运动,为植物生长创造条件,但单一的机械沙障存在易老化、维护成本高等问题,将其与乔灌草植被相结合,构建多层次、多功能、多效益的综合固沙体系,有助于进一步提高荒漠化治理成效。文章以鄂尔多斯市杭锦旗独贵塔拉镇为例,基于以往固沙模式和经验,总结了立式网格状沙障和草方格沙障与乔灌草植被相结合的配置模式与营建技术要点,并分析固沙成效,以期为该地区防沙治沙和生态保护修复工作提供一定借鉴。Mechanical sand barriers,as a simple and efficient physical sand-fixing measure,can effectively reduce surface wind speed and block the movement of sand particles,creating conditions for plant growth.However,the use of mechanical sand barriers alone has issues such as easy aging and high maintenance costs.Combining them with tree,shrub,and grass vegetation to construct a multi-layered,multifunctional,and multi-benefit comprehensive sand-fixing system can further enhance the effectiveness of desertification control.This paper takes Duguitala Town in Hangjin Banner,Ordos City,as an example.Based on previous sand-fixing patterns and experiences,it summarizes the configuration patterns and construction technical points of vertical grid sand barriers and grass grid sand barriers combined with tree,shrub,and grass vegetation,and analyzes the sand-fixing effectiveness,aiming to provide a reference for the sand prevention and desertification control as well as ecological protection and restoration work in the region.
