沙冬青与几种常见物种的防风阻沙效能定量研究

Quantitative Research on Wind and Set Sand Performance of Ammopiptanthus and Several Common Shrubs

在沙冬青生态防护方面的研究只有少量的定性描述,没有定量的结论,在一定程度上限制了其推广应用。笔者采用多通道风速风向采集仪和阶梯式集沙仪在单株水平上测定沙冬青、梭梭、沙蒿和柠条不同位置的风速和集沙量,并进行了计算和对比分析,定量揭示了沙冬青在生态防护方面的优越性,为今后干旱荒漠区生态环境建设的物种选择提供理论依据。

There were no quantitative conclusions,only small qualitative description in the study of A mmopiptanthus＇ecological protection,which limited its application to some extent.This article determined wind and set sand respectively of one Ammopiptanthus,Haloxylon,Artemisia and Caragana in different locations using multi-channel wind speed and direction acquisition instrument.Moreover,calculated anda nalyzed comparatively,showed the superiority of Ammopiptanthu in ecological protection quantitatively,top rovide a theoretical basis for the species selection in the ecological environment construction in arid deserta rea.
