Wind erosion is the main mechanism of soil desertification and soil desertification is growing more serious because of it. At the sme time, it is exacerbating the destruction of ecosystems and the ecological environment deterioration, resulting in a decline in biological productivity and land productivity in a significant recession, and leading to a serious economic loss. Soil erosion wind-tunnel experiments for a study of the physical mechanism of wind-erosion can provide experimental basis and tec...
