| Abstract: | On the base of data of Tieling observatory station and select from them the target factors of tem?perature,using estimate of lined trend and Mann-Kendall cumulative departure method to analyze the chang?ing temperature trends from 1969 to 2013 of the city. The results show that:in the past 45 years,the aver?age temperature in spring,summer,autumn and winter in Tieling showed a significant warming trend,al?though the summer warming trend is not significant.
