中文摘要	统计描述阜彩路、准东沙漠油田公路两条古尔班通古特沙漠内的油田公路扰动带内植物样方和采集不同年龄草方格内表层，次表层及草方格外的表层沙样，在室内实验分析，比较沙样粒度配比，有机质和盐分含量，初步总结出了草方格沙障对公路扰动带的生态恢复作用；降低近地表风速，草方格内积沙，表层细粒沙物质含量增加，形成稳定的沙面环境，使植物种子易于着床、生长、沙表层的有机质、盐分含量随着时间而增加，促进了生物结皮的发育
英文摘要	The Gurbantonggut Desert is the largest fixed and semi- fixed desert in China. The landforms here are dominated by the dune - chains and the branch - shaped dune - chains, it is belongs to the temperate arid desert climate, and the annual,precipitation varies in a range of 70100 mm. In this paper, a case study on the ecological restoration functions of the straw - checker sand - barriers is carried out along the Caifu and Zhundong desert oilfield highways in the Gurbantonggut Desert based on the laboratory analysis and comparison of the granularity, organic matter content and salt content in the sand samples sampled from the surface and subsurface sand layers in the plant plots, different - aged straw - checkers and the places near the straw - checkers along the disturbed belts of the highways. The results show that the straw- checkers have the functions of reducing wind speed, depositing sand, increasing the fine sand content in the surface layer, and forming a stable bed forthe germination of seeds and the growth of plants. Moreover, the straw - checkers make the organic matter content and salt content in the surface sand layer increase and the biocrust develop with the time
