以风洞实验研究了通过干扰气流而影响土壤风蚀的植被之影响作用。在研究中，将植被的影响作用视为其本身特征参数的函数。全部研究分为两部分：首先探讨了植物特征对粗糙度或零风速平面位移高度的影响。其次研究了植被覆盖度对土壤风蚀率的影响，得出如下结论：（１）位移高度与植被覆盖度之间存在幂函数关系；（２）位移高度与植被作用区面积之间的关系为线性函数关系；（３）对于行状排列的植物而言，位移高度与植物排列方向和风向之夹角的平方根成正比；（４）在覆盖度相同的条件下，均匀散布的植物对土壤风蚀的减弱作用较簇状大；（５）土壤风蚀率随植被覆盖度的减少呈指数增加。 Wind tunnel experiments were carried out to study the effects of disturbed airflow on the vegetation affected by wind erosion. In the study, the effect of vegetation was considered as a function of its own characteristic parameters. All the research is divided into two parts: Firstly, the effect of plant characteristics on roughness or zero-velocity plane displacement height is discussed. Secondly, the effect of vegetation coverage on the wind erosion rate was studied. The conclusions are as follows: (1) There exists a power function relationship between displacement height and vegetation coverage; (2) The relationship between displacement height and vegetation area is linear (3) The height of the displacement is proportional to the square root of the included angle between the direction of the plants and the direction of the wind for plants arranged in a row; (4) The uniformity of the wind erosion of the plants is reduced under the same coverage (5) Soil erosion rate increased exponentially with the decrease of vegetation coverage.
