Study of Wind Tunnel Simulation Experiment on Effects of Sand-Shifting Control Forest

This paper is based on the blown wind and sand experiment of nine different structures of sand-shifting control forests in a wind tunnel. The results are as follows: (1) Wind tunnel simulation experiment results and those got from survey and studies on sand-shifting control forest belts of different structure in field have the same regularity.(2) When tracts of shrub forests have certain coverage, the variation of plantation coverage has slight influence on sand-control effects. (3) Being affected ty forest belts, the feature of accumulated sand distribution is determined by the structure of forest belt. The corresponding type of forest belt and the most suitable coefficient of porosity can be selected according to different protected objects.
