| 摘 要： | 通过研究浑善达克沙地流动沙地上黄柳活沙障的防风固沙效益,对设置3 a后的不同类型的活沙障进行测定和分析,得出如下结论:沙障设置3 a后,沙地趋于固定,障内植物种类明显增多;设置黄柳活沙障的区域内下垫面粗糙度显著增大,风速明显减弱,而且黄柳网格沙障降低风速的能力较带状沙障强,其顺序为:4 m×4 m黄柳网格沙障>6 m×6 m黄柳网格沙障>间距4 m的黄柳带状沙障>间距6 m的黄柳带状沙障﹥流沙;当旷野平均风速为7.86 m·s-1时,只有流沙和间距6 m的黄柳带状沙障起沙,其他几类活沙障内均不起沙。

| Abstract: | The effect of living Salix gordejevii sand-barrier on the wind-breaking and sand-fixation of moving sand of Hunshandake sandland were investigated. The results were as follows: after the Salix gordejevii being planted for three years, the sandland was tending to be fixed. The species of the vegetation increased obviously, the ground roughness increased and wind-speed slowed down obviously in the area with sand-barrier. The sequence of the barrier sizes corresponding to the sand fixation effects was: 4 m×4 m>6 m×6 m>4 m>6 m>moving sand; When the wind-speed in field was 7.86 m·s-1, the sand moving were only occurred in moving sands and 6 m×6 m Salix gordejevii sand-barrier area, and had not been observed in other types of sand-barrier areas. |
