This paper used the moving average method, accumulated variance method, Morlet wavelet analysis, and Yamamoto method to analyze the mean maximum temperature and mean minimum temperature of Xilinhot from 1953 to 2009. The results are as following: the linear trend rates of mean maximum temperature and mean minimum temperature are 3.47℃/10 a and 6.26℃/10 a, existing a symmetric change clearly; annual range is weak decreasing trend and mean minimum temperature contributes most; The warming is becoming clear in 1990s; at the 57-year scales, the mean maximum temperature mainly exists 50 a and 30 a fluctuation, the mean minimum temperature mainly exists 50 a, 30 a and 18 a fluctuation; stage and mutagenicity both are not clear in the mean maximum temperature, but there are 3 stages and 1987 is the mutation year in terms of the mean minimum temperature.
