扫蚀,是指植物杆枝在风力的作用下左右摆动或上下晃动摩擦地表而引起的侵蚀现象。扫蚀的作用力来自于风,因此,扫蚀是风蚀的一种。扫蚀现象一般发生于荒坡陡崖或田间地埂处。这些部位生长的荒草灌丛在常年风力的吹动下,根部已很松动,乱风时就象扫帚一样地扫摩地面,将土刮起,然后在风的作用下飞扬而去。 Erosion, refers to the plant poles in the wind under the effect of swinging around or shaking the surface caused by erosion. The force of sabotage comes from the wind, so sabotage is a type of wind erosion. Erosion phenomenon generally occurs in the slopes of cliffs or field ground Department. The weeds and shrubs growing in these areas, under constant wind blowing, have been loosely rooted. When the wind blows, they swept the ground like a broom, they scrape the soil and fly away under the action of the wind.
