Abstract: The temporal characteristics of sandstorm in recent 50 years have been systemically analyzed based on the 1 436 times of sandstorm data observed by Minqin meteorological bureau in this period. According to mechanism of sandstorm-occurring and being linked with other meteorological factors in this area, the relationship between sandstorm and influencing factors has been primarily confirmed. Whether on the times or on the retaining interval of sandstorm-occurring, the general trend of sandstorm-occurring is decreasing, and sandstorms mostly focused on the period from March to April in a year. The research results would supply theoretic gist for controlling sand calamities and rehabilitating ecology of this region.

Key words: Minqin County, sandstorm, environmental characteristics
