Abstract: The paper aims to study the characteristics of temperature variation tendency in southeast Shanxi Province. The authors used linear trend estimation method, moving average method and mutation analysis to analyze the temperature variation characteristics in nearly 40 years in southeast Shanxi Province based on the data of 1971-2011 from 16 stations. The temporal analysis showed that the annual average temperature, the annual average maximum temperature, the annual average minimum temperature, the annual extreme maximum temperature and the annual extreme minimum temperature were all on the rise, the tendency rate of the above temperatures was 0.27℃/10 a, 0.29℃/10 a, 0.36℃/10 a, 0.18℃/10 a and 0.46℃/10 a, respectively, the mutation time was 1989. The spatial analysis showed that the warming range of the central and southeastern region was higher than that of the northern and northeastern region, and had an overall rising tendency.
