| 摘 要： | 本文分析了乌兰布和沙漠东北部风沙灾害的季节性、风沙运动矢量特征及其与林带参数之间的关系。认为：当地新垦绿洲农田防护林带主带走向与ＭＷ向垂直；主带间距采用树高１０倍的保守设计；结构设计应尽可能使冬季相疏透度在０．３５附近。

| Abstract: | This paper analyses the seasonal intensities of drifting sand disasters andtheir relations to wind-sand movement vectors and the designed parameters of the protective shelterbelts in the northeastern Ulan Buh Desert,concluding that in the local newly-develoloped oasis,the main shelterbelts should be vertical to NW. The distance between main belts of ten times the height of trees is conservative but reasonable,and it is better to fit the protectivre forests to have a penetrable parameter of0.35. |
