| Abstract: | Using meteorological data of the most frequently sandstorm-occurring region in the east of Hexi Corridor in Gansu province, this paper analyzed in detail the time-space features, causes and damages of sandstorm weather. It is pointed out that the sandstorm weather is mainly resulted from strong wind combining the special sand-dust ground environment and drought climatic background, which has resulted in at least two hundred million Yuan economic loss, and more than 50 person's death. In order to prevent or lighten sandstorm weather's disaster effectively, the prevention and countermeasure are that setting up sandstorm's monitoring, forecasting and alarming system; making the most use of cloudy water resource to increase precipitation artificially; recovering ecological vegetation to control land's desertification and then lighten sandstorm's damages. |
