中文摘要	本研究以七星湖沙漠风景区沙丘上的芦苇秸秆、向日葵秸秆和玉米秸秆平铺式沙障为研究对象,通过测定各沙障障格内以及裸沙丘近地表不同高度处的风速,对比研究了各沙障的防风效益。结果表明,①3种沙障在10cm高度处均具有明显的防风效能,且随着高度的增加,防风效能减小,从10cm到100cm高度,3种沙障的防风效能平均降幅达63%。②在沙丘迎风坡,芦苇秸秆沙障的防风效能和地表粗糙度分别是向日葵秸秆沙障的1.36倍和2.34倍,是玉米秸秆沙障的1.76倍和1.88倍;在沙丘坡顶和背风坡,玉米秸秆沙障的防风效能及地表粗糙度均显著高于另外两者(P<0.01)。③3种沙障的风速廓线均呈现出一种类似于"S"型的变化特征,而作为对照的裸沙丘风速廓线则服从典型指数函数分布。
英文摘要	The wind-breaking efficiency of low vertical sand barriers from reed straws,sunflower straws and corn straws on sand dune of Seven-Star Lake Desert Scenic Spot in the Hobq Desert was evaluated by measuring wind speed at different heights over surface inside sand barriers and on bare sand dune.The results showed that:(1)all the three types of sand barriers had obvious wind-breaking efficiency at the 10cm height.With the height increased,wind-breaking efficiency decreased.From10 cm to 100 cm height,the mean wind-breaking efficiency of the three types of sand barriers dropped by 63%.(2)on windward slope of sand dune,wind-breaking efficiency and surface roughness of reed straw sand barrier were respectively 1.36 and 2.34 times that of sunflower straw sand barriers,and respectively 1.76 and 1.88 times that of corn straw sand barriers;On crest and leeward slope of sand dune,wind-breaking efficiency and surface roughness of corn straw sand barriers were significantly higher than the other two sand barriers (P<0.01).(3)the wind velocity profiles over the three types of sand barriers showed an S-type,while wind velocity profile on bare sand dune showed as a exponential function distribution.
