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。
Only a small amount of qualitative research on the ecological protection of A. astigmatus, there is no quantitative conclusions, to a certain extent, the promotion of its application. The authors used multichannel wind speed and wind direction collector and stepped sand table instrument to measure the wind speed and sediment concentration in different positions of A. soongorica, Haloxylon ammodendron, Artemisia annua and C. korshinskii at the single plant level, and calculated and contrasted and analyzed quantitatively The superiority of A. sativa in ecological protection provides the theoretical basis for the future selection of species for the construction of ecological environment in arid desert areas.
