摘要
本文叙述防护林防沙效应的风洞模拟实验。分析比较不同结构型式防护林的流场特性及相对积沙量分布规律,得出最优结构型式为小密度灌木片林与疏透乔木林带组合结构。
This paper discribes the wind tunnel simulation of shel-tering effect of shelterbelts on sand.Compared the distributions of windvelocity and turbulent intensity and relative sand-heaped quantity ofthe different structures of shelterbelts,the conclusion is that the opti-mum structure of shelterbelt is the combination of porous arbor beltwith a large tract of low density brush.
