Exploring the law of temperature change can provide guidance for the development of agricultural production and rational utilization of climatic resources. Based on meteorological observation data of monthly air temperature in Angkang from1953 to 2016, the sliding average, Mann-Kendall mutation test and Morlet wavelet analysis were applied to analyze the variation characteristics of air temperature in Ankang in the latest 64 years. The results show that the annual average temperature, the spring temperature, the autumn temperature, the winter temperature, and the annual minimum temperature all showed an upward trend in the Ankang area in the latest 64 years, except that the summer temperature and annual extreme maximum temperature showed a slight downward trend. The greatest increase occurred in spring and winter, with the variability being 0.156°C/10a and 0.169°C/10a respectively. There are 23a and 31a cycles in the annual average temperature of the latest 64 years in Ankang, the extreme maximum temperature hanppened in the 31a cycle, and the extreme minimum temperature happened in the 6a, 13a and 30a cycle.
