| Abstract: | The process of the dust storm formation and its danger were analyzed. The soil grains of sand source area of Inner Mongolia were investigated.Results showed that the dust mainly came from the degraded grass land\,flowing sands and uncovered cultivated slopes.The relations between the wind and dust movement and the soil grains were discussed,based on which,the key technical fundamentals were put forward,and the dust storm prevention techniques were probed.\ \ |
