| 摘 要： | 有关湿润区5] 与半干旱区和干旱区半荒漠带防风固沙片状植被1～ 4 ] 以及干旱半干旱区乔木防护林带6～ 9] 防护效益的研究报道较多 ,但极端干旱区灌木固沙带防护效应的报道则很少。为此 ,我们根据塔里木沙漠公路Ｌ2 89～ 2 92 段 3ｋｍ植物固沙示范段的试验观测 ,对极端干旱区灌木固沙带的防护效应做一探讨。1 研究地区与方法1 1 灌木固沙带栽植地段概况塔里木沙漠公路Ｌ2 89～ 2 92 段 3ｋｍ植物固沙示范段地处塔克拉玛干沙漠腹地的中三点处 (Ｎ39°0 1′ ,Ｅ83°36′)。风沙地貌属复合型纵向沙垄。据中三点1995年 6月～ 1996年 5月气…

| Abstract: | Due to interference of vegetation by experiment in wind tunnel and observation in field,the boundary layer is divided into 2 sublayers approximately at the vegetation height.As for the vertical wind gradient,it changes disorderly in rough sublayer of the lower and changes regularly in inertial sublayer of the upper varying with vegetation characteristics.Erosion rate increases exponentially with vegetation coverage reduction.The establishment of shrub shelterbelt along Tarim Desert Highway made obvious effects not only on wind preventing and sand binding,but also on microclimate.Compared with mobile dune,air temperature is higher in summer and lower in autumn,while relative moisture is higher,and evaporation and soil temperature lower in the shrub shelterbelt. |
