Revegetation is a widely used way to minimise aeolian sediment transport in desertified land. An optimal vegetation density and planting pattern reduces the economic investment for revegetation and competition for limited water resources. This study aimed to ascertain the effects of vegetation density and planting pattern on aeolian sediment transport at the regional scale. A series of wind tunnel tests were implemented with artificial shrubs representing Haloxylon ammodendron. These tests were designed with three planting densities (i.e., 600 plants ha⁻¹, 1200 plants ha⁻¹, and 1650 plants ha⁻¹) and four patterns (uniform distribution, random distribution, two rows/one belt, and one row/one belt pattern). Geostatistical interpolation methods available in ArcGIS were used to analyse the spatial variation of sand heights. Vegetation density and planting pattern and their interaction all significantly affected the aeolian sediment transport but vegetation density had the greatest impact. With increasing density of vegetation, wind erosion rate decreased significantly following quadratic function, and wind erosion still occurred around the artificial shrubs regardless of vegetation density and planting pattern. For wind erosion rate, erosion and deposition area, the uniform distribution pattern had little protective benefit at the three planting densities, whilst the combinations of the random distribution pattern with 600 plants ha⁻¹, two rows/one belt pattern with 1200 plants ha⁻¹, and one row/one belt pattern with 1650 plants ha⁻¹ had the best protective benefit in controlling the aeolian sediment transport.

重新植被是一种广泛使用的方法，可以最大限度地减少荒漠化土地上的风沙输送。最佳的植被密度和种植模式减少了重新植被的经济投资和对有限水资源的竞争。本研究旨在确定植被密度和种植模式在区域尺度上对风积沉积物输送的影响。使用代表梭梭的人造灌木进行了一系列风洞试验。这些测试设计为具有三种种植密度（即 600 株公顷^-1、1200 株公顷^-1和 1650 株公顷^-1) 和四种图案（均匀分布、随机分布、两排/一带和一排/一带图案）。ArcGIS 中可用的地统计插值方法用于分析沙子高度的空间变化。植被密度和种植模式及其相互作用都显着影响风沙输移，但植被密度的影响最大。随着植被密度的增加，风蚀率呈二次函数显着下降，无论植被密度和种植方式如何，人工灌木周围仍然存在风蚀。对于风蚀率、侵蚀沉积面积，均匀分布模式在三种种植密度下几乎没有保护效益，而随机分布模式与600株植物的组合公顷^-1、两行一带状1200株公顷^-1和一行一带状1650株公顷^-1对控制风沙输移的保护效果最好。
