中文摘要	为科学治理黄河乌兰布和沙漠沿岸风沙入黄问题,以该河段沿线流沙为对照,开展了麦草沙障、沙柳沙障、葵花杆沙障和梭梭林为代表的工程与植物固沙实验,对不同治理措施下的风速廓线、粗糙度、风沙流结构、防护效果及其相互关系进行了野外观测与室内分析。结果表明: 1)各沙障和梭梭林内风速廓线发生改变,近地表风速显著降低,地表粗糙度和摩阻风速显著增加。2)流沙表面输沙量分布随高度增加呈对数递减, 90%集中在0 ~ 10cm范围,98%分布在0 ~ 30m范围内。3)不同措施的输沙率随风速的增加呈增加趋势,但输沙率仅为流沙的1.07% ~ 38.27%,可很好的控制近地表的流沙活动。4)各类固沙措施的实施效果排序葵花杆沙障> 梭梭林> 沙柳沙障> 麦草沙障,控制流沙效果均达到75%以上,对固定流沙均能起到积极作用。综合考虑固沙效果、成本、运输以及使用寿命等,该地区选择葵花杆沙障和梭梭较为合适。该研究结果可为解决风沙入黄问题、完善黄河沿岸风沙防护体系提供参考。
英文摘要	For scientific management of the Yellow River in Ulan Buh Desert section to control the sand along the bank shifting into the river,the engineering and sand - fixation plant experiments,including straw barrier,salix sandy barrier,sunflower stem barrier and Haloxylon ammodendron (C. A. Mey.) Bunge,were carried out; the wind speed profile,roughness,sand flow structure and the protective effects under different control measures, and their relationships were observed and analyzed. Results show that: 1) The wind velocity profile changed, near - surface wind speed significantly reduced,surface roughness and friction velocity increased significantly in the barriers and Haloxylon ammodendron forest. 2) The sediment discharge distribution on shifting sand surface showed a logarithmic decrement with height increase; 90% of it concentrated in the range of 0 ~ 10cm height, 98% of it distributed in range of 0 ~ 30cm. 3) Sand transport rates for different measures increased with wind speed increasing,but the sediment transport rate was only 1.07% ~ 38.27% of the shifting sand; so the measures effectively controlled the sand shifting activity near surface. 4) The sand - fixation effects of all kinds of measures were sunflower stem > Haloxylon ammodendron > Salix psammophila > straw barrier; the shifting sand control effects were all of 75% above. Comprehensively considering the sand - fixation effects,transportation costs and service life,etc.,sunflower stem barrier and Haloxylon ammodendron were relatively appropriate for the region.
