摘  要:
对腾格里和库布齐沙漠公路不同固沙措施的防风固沙作用和运行成笨进行综合比较,结果表明,受沙障材料、设置规格、使用寿命的影响,不同沙障的防风固沙作用不同;沙障的防护作用随着沙障的破损而减弱;人工植被的防护作用随着建植时间的延长而增长。从运行成本分析,沙柳和柴草沙障成本低,土工材料和土壤凝结剂沙障运行成本较高,人工植被运行成本最高,实践中宜因地制宜采取不同的固沙措施。

摘  要:
The authors mainly compared with the effect of wind-break and sand-fixing of different sand-fixing measures of Tengli and Kubuqi desert highway.The results were as follows.The effect of wind break and sand control of different sand-barriers was different which affected by material,size and using life;the defence effect of sand-barriers reduced along with the damage degree of sand-barriers.But the defence effect of artificial vegetationincreased along with increasing of extending planting time.The cost of osier sand-barriers and oaten sand-barriers was the lowest and the cost of macromolecule plastic-bag sand-barriers and soil coagulant sand-barriers were higher,and then the cost of artificial vegetation is the highest.The sand-fixing measures fitting local condition should be selected on desert highway.
