摘要:

分析戈壁砾石盖度与不同梭梭(Haloxylon ammodendron)配置复合作用下的防风效能,可以为戈壁地区防风固沙林建设提供理论依据。本文对不同风速作用下2种砾石盖度(6.53%和43.96%)、2种林带高度(15 cm和30 cm)结合3种林带配置模式(单行、两行、三行配置)梭梭林的流场变化规律进行了风洞模拟试验。结果表明:15 cm和30 cm高度梭梭林带的流场结构相似,均在梭梭高度范围内对气流有削减作用;同一砾石盖度下三行梭梭配置的流场风影区面积及风影区存在距离均大于单行和两行梭梭配置;砾石盖度43.69%和30 cm高度梭梭林带组合较其他组合的等风速线抬升幅度明显增加;单行、两行、三行梭梭配置防风效能在背风侧0~2倍株高处达到最大值后逐渐减小,最大平均防风效能分别为23.9%、37.85%和45.4%,梭梭高度增加林带背风侧3倍株高处防风效能出现抬升现象,从而延伸防护距离。

Abstract:

The analysis of the windbreak efficiency under the combined effect of gobi gravel coverage and different Haloxylon ammodendron configuration can provide a theoretical basis for the construction of windbreak and sand-fixing forest in gobi area. In this paper, the wind tunnel simulation test was carried out on the flow field variation of H. ammodendron forest with two kinds of gravel coverage (6.53% and 43.96%), two kinds of forest belt height (15 cm and 30 cm) and three kinds of forest belt configuration modes (single row, two rows and three rows) under different wind speeds. The results showed that the flow field structures of 15 cm and 30 cm height H.ammodendron forest belts were similar, both of which had a reducing effect on the airflow within the height range of H.ammodendron. Under the same gravel coverage, the wind shadow area and the distance of the wind shadow area of the flow field of the three-row H. ammodendron configuration are larger than those of the single-row and two-row H. ammodendron configurations; gravel coverage of 43.69% and 30 cm height of H. ammodendron forest belt combination than other combinations of contour wind speed line rise significantly increased; the windproof efficiency of single row, two rows and three rows of H. ammodendron configuration reached the maximum value at 0-2 times plant height on the leeward side and then gradually decreased, and the maximum average windproof efficiency was 23.9%, 37.85% and 45.4%, respectively. The height of H. ammodendron increased the windproof efficiency at 3 times plant height on the leeward side of the forest belt, which extended the protection distance.
