摘要

对毛乌素沙地15

25和 35 cm的3个高度

1 m×0.5 m

1 m×1 m

1 m×2 m

2 m×2 m

2 m×3 m 5种规格的半隐蔽格状沙柳沙障内近地表风沙流的活动过程进行了对比研究

分析了不同规格沙障的防风阻沙效益。结果表明

设置沙柳沙障后地表土壤中细粒物质含量明显增加;与裸沙丘相比

沙柳沙障内的相对输沙率明显减少。根据当地的自然条件和经济状况

认为毛乌素沙地适宜于当地铺设的沙柳沙障规格为2 m×2 m。

Abstract

Five sizes of Salix psammophila checkerboard sand barriers (1×0.5

1×1

1×2

2×2 and 2×3 m2 in size; 15

25 and 35 cm in height) in Mu Us sand land were set and the processes of sand flow near dune surface were analyzed in order to determine the protective benefits of the sand barriers. Results showed that the component of fine powder on dune surface increased obviously by Salix psammophila checkerboard. Compared with bare dune

the sand flux relative-intensity of checkerboard was reduced obviously. Combined with the local natural conditions and economic factors

the 2 m×2 m Salix psammophila checkerboard sand barrier is suitable for windbreak and desertification control in Mu Us sand land.
