Despite many studies describing wind speed and sediment flux profiles in various situations, wind tunnel observations in the presence of live vegetation are infrequent and rarely combined with field measurements. To investigate the structure of wind speed and sediment flux profiles in morphologically different vegetation and various plant densities, wind velocity and sediment flux profiles were obtained over a multi-row windbreak in an arid environment and over unplanted surfaces and canopies of two types of plants in a wind tunnel. Although the two plant types in the wind tunnel have different morphology, the profiles of wind velocity and sediment flux showed structures similar to those for other plant types reported in previous studies which indicates that profile structures are likely common for homogeneous canopies even with different plant morphology and in various wind velocities. The horizontal profiles of wind speed and vertical profiles of sediment flux in the wind tunnel closely matched the profiles in the field-scale windbreak. The vertical profiles of wind speed within the wind-tunnel vegetation exhibited a deflection which was not reflected within the multi-row windbreak where profiles were nearly uniform without inflections, which was likely a response to different plant spacing and patterns. Wind-tunnel vegetation reduced wind speed significantly even in low density. Lowest wind speeds were observed beyond the wind-tunnel canopies and at the beginning of the windbreak. No difference in the size of the sheltered zone is observed between the two plant types in the wind tunnel either in different wind velocities or in various density configurations, or within the windbreak in various wind speeds and different dust storm events. The sheltered area was greater for the windbreak than for the wind-tunnel canopies, suggesting that wind tunnel studies may under-estimate the sheltered area afforded by a multi-row windbreak.

尽管有许多研究描述了在各种情况下的风速和沉积物通量剖面，但在有活植被的情况下进行风洞观测的情况很少，并且很少与野外测量相结合。为了研究形态不同的植被和各种植物密度下的风速和泥沙通量结构，在干旱环境中多行防风林和两种植物的未种植表面和冠层上获得了风速和泥沙通量轮廓。风洞。尽管风洞中的两种植物具有不同的形态，风速和泥沙通量的剖面显示出与先前研究中报道的其他植物类型相似的结构，这表明即使植物形态和风速不同，均质冠层也可能具有相同的剖面结构。风洞中的风速水平剖面和泥沙通量的垂直剖面与田间规模防风林中的剖面紧密匹配。风洞植被内风速的垂直剖面显示出偏转，该偏移未在多行防风区内反映出来，在多排防风区内，剖面几乎是均匀的，没有弯曲，这可能是对不同植物间距和样式的响应。即使在低密度下，风洞植被也会显着降低风速。在风洞顶盖之外和防风开始时，观察到最低风速。在风速不同或密度不同的风洞中，或在风速不同和沙尘暴事件不同的防风林中，风洞中两种植物类型之间的庇护区大小均未发现差异。防风林的庇护所面积比风洞顶篷大，这表明风洞研究可能低估了多行防风林所提供的庇护所面积。
