Abstract: The data of meteorological and the rice yield In Yanbian region from 1980 to 2011 was used in this paper, in order to analyze the regulation of the meteorological factors of accumulated temperature, rainfall and Sunshine hours and its influence on the meteorological yield of rice. By correlation analysis and partial correlation analysis, we found the meteorological of rice had a significant positive correlation with the rainfall and sunshine hours ,had not correlation with accumulated temperature, and the regression equation of the meteorological yield and accumulated temperature, rainfall and sunshine was got by the Multiple linear regression analysis. And the average accumulated temperature and sunshine hours were increased 6.7℃ and 3.8h annually, while rainfall was decreased 4mm per year. With the intensity of the phenomena of climate warming and rainfall reduction in Yanbian prefecture, the impact on drought and Rice yield will become heavy.
