中文摘要	本文以库布齐沙漠穿沙公路和神东公司巴图塔沙柳基地为试验区，对高立式沙柳沙障风速和输沙量进行了野外观测，根据调查和观测资料，利用suffer（8．8）软件作出高立式沙柳沙障体系内外的风速流场图，并运用粗糙度（Z0）为物理参数对沙柳沙障的防风效益和阻沙作用进行了系统的研究分析。结果表明：复式带状高立式沙柳沙障体系内外风速变化较明显，2m高风速呈现出在防沙体系的带前增强，带内平缓，带后减弱的趋势，而0．5m高度的风速在防沙体系内更趋向干平缓而稳定的变化；障前4H-10H范围内下垫面粗糙度变化不大，障间粗糙度明显增大，障后3H-4H处的粗糙度比障问粗糙度降低了72％；当旷野风速大干起沙风速时，复式带状沙柳沙障防护体系内外，风速比（V2m／V0.5m）与输沙量的关系呈对数函数；无高立式沙柳沙障存在时，风沙流甚至直接威胁路面，沙丘移动具有前进、后退、又前进，随风向的变化往复式移动的特点。
英文摘要	The high Salix deserts barrier along the highway of crossing kubuqi desert and Batuta Salix base was observed. Then, according to the observation, by use of the software of Surfer（8.8） for the wind speed flow chart and the benefit of wind - breaking and sand - binding of Salix deserts barrier with roughness length and roughed wind speed was systematically analyzed. Besides, the effects of Salix deserts barrier for the highway of crossing kubuqi desert were explained. The result showed that the double high salix deserts barrier can bring obvious change of wind speed inside and outside system. The 2m high wind speed present in the system of control sand ,the former is increasing , the later is decreasing and inside is smooth, but 0.5m high wind speed treed to smooth and steady; the roughness length of earth＇s surface is smooth in 4H - 10H former, but barrier inside is obvious increase, in 3H - 4H barrier later lower over 72% of the roughness length, the function of logarithm between the wind speed ratio （ V2m/V0.5m ） and sand - binding when field wind speed is enlarge than leaving speed. If there is no barrier of control sand, the wind speed of sand will threat highway directly, the character of dune moving has advance , back and advance, with the direction of wind move to and fro. the highway Salix deserts barrier protection system to control the quicksand completely, removing the sandstorm to flow to move the bane toward the highway with sand dune before, is a kind of very valid protective system.
