中文摘要	通过野外试验探究了流动沙丘中上部导风板板后作用区风速特性和输沙量特征,结果表明:不同角度导风板对板后风速增加的区域有所不同,作用区内最大风速一般出现于板后1.5 m, 45°导风板对于板后1.5 m处风速加速效果明显,板后3.0 m处则是25°导风板加速效果较为明显,而在板后4.5 m处影响效果明显的导风板角度为35°。导风板可以有效的提高板后输沙总量,其中30° ~ 45°区间的中等角度导风板对于输沙量的提升具有明显效果, 45°导风板对于板后1.5 m处输沙量提升效果较高,而40°导风板对于板后3.0 m处输沙量提升效果较高,在板后4.5 m处则是30°导风板提升效果较高。
英文摘要	In this study, the field experiments on the effect of wind guide plate in preventing wind-drift sand was carried out so as to reveal the characteristics of wind speed and sediment discharge behind the wind guide plate. The purposes of the study were to explore the effects of wind deflector on wind velocity and sediment discharge in the middle and upper parts of mobile dune. The results showed that the area where the wind speed was increased behind the wind guide plate was different from the different dip angles of the plate. In general, the maximum wind speed occurred behind the plate for 1.5 m,and the effect of increasing wind speed of the wind guide plate with 45° was significant behind the plate for 1.5 m, that with 25° was significant behind the plate for 3.0 m,and that with 35° was significant behind the plate for 4.5 m. The wind guide plate could be used to effectively increase the total sediment discharge behind the plate, in which the effect of increasing sediment discharge of the mid-angle wind guide plate in a range of 30° - 45° was more obvious. The effect of increasing sediment discharge of the wind guide plate with 45° was significant behind the plate for 1.5 m,that with 40° was significant behind the plate for 3.0 m, that with 30° was significant behind the plate for 4.5 m.
