Abstract:  Global warming has become a widespread concern society as a whole in recent years, and desert climate was worth to pay more attention under global warming. Climate change, including the temperature, precipitation, air humidity, wind speed and sunshine in Minqin during 1961-2009, was analyzed in the paper. The results showed that the increasing rate of annual average temperature in Minqin desert area was higher than the national average, especially in spring and winter, but lower than northeast and northwest of China. The variation of annual average temperature, annual precipitation, annual average air relative humidity, average wind speed and sunshine hours changed in different stages. The highest temperature fluctuation increased significantly, instability of desert climate was stronger. The annual average wind speed and air humidity decreased. There was positive correlation between air humidity and precipitation (P<0.05), and negative correlation between annual average wind speed and air relative humidity (P<0.01).

Key words: Desert climate, Global warming, Stage, Minqin
