| Abstract: | The frequent attacks of strong and extraordinarily strong dust devil in the northern China in recent years are closely related to the serious destruction of the vegetation in the region in recent decades, the increasing expansion of the desertification area, the increase of sand sources due to eco environmental deterioration, the warming up of climate and the weakening of the resisting capacity of our natural environment against dust devil. Measures for preventing and controlling dust devil are to improve the eco environment by increasing vegetation, establish a dust devil pre warning system and a dynamic monitoring & forecast system for dust dveil frequent areas, and enhance the enforcement of laws and administrative efforts so as to bring the eco environment construction of dust devil afflicted areas into the orbit of laws. |
