摘  要:
通过分析研究民勤流沙治理中机械沙障的防风固沙效益,对设置的6种不同类型沙障进行测定和分析,得出如下结论:机械沙障设置后,可以提高流沙下垫面的粗糙度,降低近地表风速,固定流沙,减少风速。6种机械措施相比,塑料网格沙障价值系数最高,依次为:粘土方格沙障、麦草方格沙障、土工编织袋沙障、砾石方格沙障、棉花秆方格沙障。

摘  要:
The effect of living six types of sand-barrier on the wind-breaking and sand-fixation of moving sand of Minqin sand land were investigated.The results showed: The sand land was tending to be fixed after the sand-barrier set.The ground roughness increased and wind-speed slowed down obviously in the area with sand-barrier.The sequence of the different sand-barrier to the values was as follows: sand-barrier Ⅴ>sand-barrier Ⅱ>sand-bar-rier Ⅰ>sand-barrier Ⅵ>sand-barrier Ⅳ>sand-barrier Ⅲ.
