| 摘 要： | 通过对肠式沙障沙埋程度、积沙宽度、位移程度及沙障控制区域植被盖度等指标进行调查,分别研究了不同规格、不同类型的肠式沙障稳定性及其所在沙丘植被恢复程度。研究结果表明:品字沙障位移距离最大,移动平均距离达到了58.72 cm,方格沙障移动距离最小,仅为36.11 cm。4 m品字形沙障的移动距离最大,达到了70.67 cm,2 m带状沙障的次之,移动距离为52.33 cm,说明规格越大,移动程度也越大。方格沙障铺设沙丘的植被盖度较大,其中4 m×4 m方格沙障铺设沙丘植被盖度达到最大。

| Abstract: | Through investigating the sand burial degree, width of accumulated sand, displacement distance of intestinal type sand barrier and the vegetation coverage in the controlling area of sand barrier, the stability of intestinal type sand barrier in different size and type and the restoration of vegetation in dune have been studied. The results show that the displacement distance of 品 - type sand barrier is the longest, with the average movement distance reaching to 58.72 cm, the displacement distance of checkboard sand barrier is the shortest, only reaching to 36.11 cm. The displacement distance of 4 m 品 - type sand barrier is the longest, with reaching to 70.67 cm, and the one of 2 m belt sand barrier is 52.33 cm, which shows that the bigger the size is, the longer the displacement distance is. The vegetation coverage in the dune with checkboard sand barrier is bigger, which the one in 4 m× 4 m checkboard sand barrier is the biggest. |
