Abstract: The actual winter wheat yield data during 2003-2009 were investigated inhome based on household in three villages, and the method of linear sliding average was used to remove trend yield of winter wheat, then the climatic yield was calculated. The correlation between climatic yield and meteorological data adjacent to three villages was analyzed. The results showed that precipitation of seedingbefore winter, sunshine hours of fillingmilk stage, and average temperature of filling stage were key meteorological factors to influence winter wheat yield, which appeared as drought disaster during seedling stage, cloudy drizzly conditions during fillingmilk stage and high temperature during filling stage. The results could provide technical support for winter wheat production. 
