Abstract: Employing the meteorological observation data from 1961 to 2010 of the meteorological station in Liangzhou District, Wuwei City, and using the mathematical statistics method, the climate change characteristics were analyzed systematically including the temperature, precipitation and sunshine hours in winter. The results showed that: the temperature in winter significantly increased, and the climate tendency rate was 0.617℃/10 a, which passed the significance level test of 99%; the precipitation in winter increased slightly, and the climate tendency rate was 0.107 mm/10 a; sunshine hours had a slight decrease tendency, and the climate tendency rate was -1.6721 h/10 a. The climate tendency coefficient of precipitation and sunshine hours did not pass the significance level test. Under the background of climate warming in winter, solar greenhouse would face multiple impacts, so a series of countermeasures were proposed to deal with climate change in winter, which would provide a scientific basis for high yield and bumper harvest.
