摘　　要：通过观测和研究 ,得出风沙区农田防护林带的走向与主风方向的交角 ,不能小于 45° ,主林带间距 15 0m——— 2 0 0m ,副林带间距 2 3 0m——— 70 0m ,林带结构以疏透结构为最好 ,主林带一般由主林木 5— 6行组成 ,副林带由 2— 3行组成 ,再在迎风面和背风面配置 1行—Through observation and study,the optimum designing programs are showed as follows:the cross degree between shelter belt and do minant wind direction should be more than 45 degree,the main forest belt distance should be from 150 meter to 200 meter,the subbelt distance should be from 230 meter to 700 meter,the best belt structure is sparse and transparent structure.The main forest shelter belt consist of 5—6 lines.The sub forest shelter belt consist of 2—3 lines,additionally,1—2 lines shrub and coniferous trees should be planted in the facing wind side and sheltered side.
