摘要:
 人工固沙林建设中,通过风洞模拟试验,研究丛状、两行一带、单行一带和均匀4种固沙林配置模式的防风阻沙效果。结果表明:1)在植被覆盖度均为20%的条件下,4种配置模式的固沙林都有显著降低风速的效果;4种配置在林带前和林带后风速变化差异不大,林带内风速变化差异显著,均匀和丛状2种配置模式降低风速的效果优于两行一带和单行一带,其中丛状配置在近地面防风效果最好;2)4种固沙林配置在林带内阻固沙效果明显,林带前、后均出现不同程度的风蚀,风蚀和积沙量随着风速的增加而增加,积沙总量:丛状>均匀>单行一带>两行一带。研究结果表明,丛状固沙林配置模式在综合防风、阻沙效果方面优于其他3种模式,此结果可为干旱沙区固沙林建设提供新的造林模式。
Abstract:
 The construction of artificial sand-fixing shrub is one of the most effective measures for ecological reconstruction and sand damage control in sandy area.The scientific and reasonable density and spatial distribution of the shrubs in afforestation are the keys to ensure the sustainable and stable growth of the shrubs,and to play good protection functions to the oasis.This article studied the wind-breaking and sand-blocking effects of sand-fixation shrubs with four spatial distribution patterns,namely,cluster pattern,two-line-shelter belt,one-line-shelter belt and even spacing under different wind speeds through wind tunnel simulation experiment.The results showed that 1) under the vegetation coverage of 20%,all the four patterns could significantly reduce wind speed.There was no significant difference in wind speed among the four patterns in front of and behind the shrub belts,whereas the wind speed inside the shrub belts varied significantly.The wind speed reducing effects of the even spacing and the cluster pattern were better than those of two-line-shelter belt and one-line-shelter belt,and the cluster pattern was effective in wind-breaking near the ground.2) The sand-blocking effect of the four patterns was good inside the shrub belt,wind erosion appeared in front of and behind the shrub belt.The amount of the sand eroded and accumulated increased with wind speed.The total amount of accumulated sand ranked as the cluster pattern>even spacing>one-line-shelter belt>two-line-shelter belt.It is that the cluster pattern is superior to the other three patterns in the comprehensive wind-breaking and sand-fixing effects.This results can provide a new afforestation pattern for the construction of artificial sand-fixing shrub in arid sandy area.
