Abstract: In this paper, the monthly data set of ground meteorological elements in China provided by the China Meteorological Administration is used to model and analyze the temperature data of China in 1951-2019. The trend of temperature change in china over the past 70 years is studied by scatter plots and linear regressions and the spatiotemporal characteristics of meteorological factors are analyzed by Empirical Ortho-gonal Function models, and the temperature change in china over the next 25 years is predicted by Grey Pre-diction and Time Series Model. The results show that under the background of global warming, the tempera-ture in China is on the rise in many latitudes, and will rise about 0.6-0.8 degrees Celsius in 25 years.
