- Abstract:
-
The typical steppe in Xilingol League of Inner Mongolia was selected as studied area. The quantitative analysis on the effect of vegetation cover on wind erosion was carried out by means of wind tunnel simulation experiment, which aimed at discussing the characteristics of threshold wind velocity, sandstorm structure and rate of wind erosion under different vegetation coverage. The results show that the threshold wind velocity increases with the increase of vegetation coverage. Influenced by vegetation, sandstorm structure presents the leaping distribution. The sand transfer rate decreases with the increase of vegetation coverage in the lower layer, and the height layer of the maximum sand transfer rate increases. The relationship between the total sediment discharge and wind speed follows the power function under different vegetation coverage. The total sediment discharge decreases gradually with the increase of vegetation coverage under the same wind speed. The conclusion will provide the theoretical basis for development of the reasonable sand-fixation technology.
