本文分析了几种沙障在工程扰动区的固沙试验及沙障内植被恢复效果,结果表明,各沙障风速降低比32.99%～38.44%,均起到了较好的防风阻沙效果,但各措施的防风差异不明显。为植被的恢复和生长创造了良好的生活环境。各种沙障在2年的植被恢复过程中,低立式沙柳沙障的植被恢复效果最为明显,其生长的植被以较高级的生物种组成,生态稳定性较强,自然植被的丰富度指数差异不明显,植被组成和生活型有较显著的差异。1.0m×1.0m沙袋沙障植被总覆盖度为38%,效果较好。
In this paper, we analyzed the sand fixation test and the vegetation restoration effect in the sand disturbance zone with several sand barriers. The results show that the wind speed of each sand barrier is reduced by 32.99% ~ 38.44% Wind protection differences are not obvious. For the restoration and growth of vegetation has created a good living environment. All kinds of sand barriers During the two years of vegetation restoration, the relief effect of low Salix saffran shelter is most obvious. The vegetation that grows is composed of higher biological species with strong ecological stability and the richness of natural vegetation The index difference is not obvious, the vegetation composition and life form have significant differences. The total vegetation coverage of 1.0m × 1.0m sandbag sand barrier is 38%, which has good effect.
