Although the effectiveness of windbreaks in reducing wind speed and sediment transport is highly dependent on the efficiency of individual elements, few field studies have evaluated the effectiveness of single plants typical of arid areas such as Tamarix. A series field experiments were conducted in the Niatak area of Sistan to assess the effectiveness of a single Tamarix tree in reducing wind speed and sediment flux. Wind speed was measured on five occasions at 32 positions around the tree and at heights of z/h = 0.13, 0.5, 1.1, and 2 (where h is the height of the tree). Sediment flux was measured over three dust storm events at 15 positions and at heights of z/h = 0.13, 0.5, 1.1, and 1.8. The results showed a reduction of wind speed and sediment flux of 80–90% at x/h = 1, decreasing to about 5–8% at x/h = 12. There was an acceleration of about 12–20% in wind speed and about 25–35% in sediment flux around the sides of the tree. The tree sheltered a zone of x/h = 7–9 downwind and the pattern of the sediment transport reduction closely conformed to that of the wind speed reduction. The greatest reduction of wind speed and sediment flux was observed on the leeside of the tree at x/h = 0.5 and, 1 and close to the ground surface. The results confirm the effectiveness of Tamarix trees in reducing wind speed and sediment flux, and thus its suitability as a potential control on erosion and sediment transport. Based on the results, designing a windbreak with an optimum inter-rows distance of x/h = 7 and inter-plant spacing of less than 0.5 h is suggested in order to provide maximum control of aeolian erosion.

尽管防风林在降低风速和泥沙输送方面的有效性高度依赖于单个要素的有效性，但很少有田间研究评估干旱地区（如塔马里克斯）典型的单株植物的有效性。在锡斯坦（Sistan）的尼亚塔（Niatak）地区进行了一系列野外试验，以评估一棵Ta柳在降低风速和沉积物通量方面的有效性。在树木周围32个位置上的五次测量风速，z / h的高度分别为 0.13、0.5、1.1和2（其中h是树木的高度）。在15个位置和z / h高度的三个沙尘暴事件中测量了泥沙通量 = 0.13、0.5、1.1和1.8。结果表明降低风速和在X / 80-90％沉积通量的ħ  = 1，当x /减少至约5-8％ħ  = 12有大约12-20％的风速的加速度树木两侧的泥沙流量约为25–35％。树木 在下风处掩盖了x / h = 7–9的区域，沉积物迁移减少的模式与风速减少的模式非常吻合。在树的背风处观察到风速和泥沙通量最大降低，x / h  = 0.5，且1且靠近地面。结果证实了Tamarix的有效性降低风速和泥沙通量，从而使其适合作为侵蚀和泥沙输送的潜在控制手段。根据结果​​，建议设计一种行间风距，其最佳行间距离为x / h  = 7，并且植物间间距小于0.5 h，以便最大程度地控制风蚀。
