【 摘 要 】

The trends of mean temperature, maximum temperature (Tmax) and minimum temperature (Tmin) data from Naiman National automatic meteorological station were analyzed on annual, seasonal and monthly scales over the 1970-2013 periods. Results indicated: (1) The average annual mean temperature, Tmax and Tmin in Naiman County was 7.1°C, 13.5°C and 1.6°C, respectively, and average annual mean temperature, Tmax and Tmin all increased, at a rate of of 0.29°C/10a, 0.24°C/10a and 0.28°C/10a, respectively, which were all higher than global nearly 50 years (0.13°C/10a); (2) The average annual mean temperature of spring, summer, autumn and winter was 8.3°C, 22.6°C, 7.7°C and -10.1°C, respectively; The increasing speed of mean temperature, Tmax and Tmin were all most obviously at spring, at a rate of 0.38°C/10a, 0.3°C/10a and 0.38°C/10a, respectively; (3) The highest and lowest mean temperature was obtained at July (23.9°C) and January (-12.3°C), respectively; The highest and lowest Tmax was obtained at July (23.9°C) and January (-5.9°C), and the highest and lowest Tmin was obtained at July (19.1°C) and Dec. (-14.3°C).
