Sand storm is liable to occur in the arid, blustery, overgrazing and desertification area. So not having a enhanced solid can be a serious obstacle preventing human form reducing the frequency of it. Planting trees, enlarging the area of forest, and establishing the ecological barrier are the best way to strength the solid. Planting a number of trees that are appropriate for the local climate in the edge of city is a effective way to prevent sand storm invasion. In addition, the government should adopt some ways to improve people’s conscious of environmental protection.
The exact role of another ways concerning the prevention of sand storm is that the government provokes farmers to replace the crops on their farmland with trees or grassland, recovering the protection of natural ecological zone.
