为减轻土壤风蚀危害，在河北坝上地区农田起垄的方向宜采用与自然风向NW（西北风向，315°）成90°，即东北方向45°。

Therefore , the direction of field ridge in Heibei Bashang region is suitable with 90 ° to NW ( natural wind direction 315 °), that is the direction in NE ( 45 °) .

在土壤风蚀研究中，Bagnold建立的干沙子的起动风速与沙粒粒径关系的表达式已被广泛接受。

The widely accepted Bagnold type function to calculate threshold wind velocity or shear velocity was developed for dry sands .

由于直立残茬和植被覆盖的共同作用结果，风洞集沙仪收集的保护性耕作农田最大土壤风蚀量集中在距地表18～40cm的高度范围内。

As the result of the co-action of the erect stubble and vegetation cover , The position that the maximum soil wind erosion amount for conservation tillage farmland measured by sand sampler located in the height range of 18 ~ 40cm .
