An experimental study of the Zhao He grassland soil wind erosion characteristics on the northern foothills of Yin Shan Mountain

摘要

The soil erosion test was carried out for the Zhao He grassland on the northern foothills of Yin Shan Mountain by the use of a portable wind erosion tunnel developed by Inner Mongolia Agricultural University, the variation low of soil wind erosion rate with the different wind speed and different arrangement in pairs of different soil moisture content and different vegetation coverage was obtained and the data analysis indicates that the anti-wind erosion characteristics of ground surface is most satisfactory when the vegetation coverage is 40%, soil moisture content 9.3% and the height of vegetation 50cm. The result of this study may provide a certain reference date for the application of prevention and control technology of soil wind erosion and be of vital significance to the implementation of sustainable development of livestock husbandry.
