摘要

依据在新疆西北部对人工梭梭林定位观测结果

研究了梭梭林的生态价值和经济功能。结果表明

人工梭梭灌草林带对近地层气流的阻力可增加1.2~6.6倍

灌草带越宽

降低近地层风速的作用愈显著。130 m宽梭梭灌草带阻截流沙量达到95%左右。观测表明

要将流沙有效地阻截在绿洲外围

梭梭灌草带的宽度应不少于130 m为宜。灌草带内的温度状况与带的宽度和植物盖度密切相关

保持梭梭灌草带一定的盖度和宽度

对改善梭梭灌草带内空气湿度状况具有重要意义。

Abstract

According to the located observation for the artificial Haloxylon ammodendron forest in Northwest Xinjiang Wei Autonomous Region

we analyzed its ecological value and economic functions.Results indicate that the air current resistance of forest belt to close stratum may increase 1.2～6.6 times.Moreover

the wider the belt

the more notable the effect.The 130 m wide forest belt can block and intercept about 95 % of drift-sand.The observation shows that the better width of forest belt is more than 130 m in order to make drift-sand to be blocked and intercepted effectively in the oasis periphery.The inner temperature of forest belt has the closer correlations with its width and plant coverage degree

so there is an important significance to improve its inner air humidity by keeping forest belt with a certain coverage degree and width.
