Based on the observational data from meteorological stations of Yingkou region in recent sixty years, the characteristic analysis of trends, periodicity and mutation for the climatic elements such as annual and seasonal mean air temperature were performed, which was using the linear regression, wavelet transform, Mann-Kendall test and Rescaled Range analysis. The results indicated that air temperature was in an increasing trend in recent 60 years approximately in the study area, and the climatic tendency rate was 0.32℃/decade for annual average temperature, and 0.42℃/decade, 0.17℃/decade, 0.23℃/decade and 0.47℃/decade for the mean temperature of spring, summer, autumn and winter, respectively. The annual average temperature of Yingkou region had significant periods of deferent time scale, with quasi-2years, 4years, 6 to 7years and 16 years. The period of 4 years appeared after 1980s and the period of 16 years were exploded before 1970s. During 60 years approximately, there were significant warmer years of annual mean temperature in 1998 and 2007, whereas anomalous colder summer and anomalous warmer winter was in 1976 and 2007 respectively. By the abrupt change detecting with Mann-Kendall test, the results showed that the annual mean temperature had a sudden change in 1988. Moreover, it will maintain the original warming trend in the future, especially in the spring and winter.
