| Abstract: | 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. |
