In this paper, the Rank Correlation methods (Mann-Kendall test, M-K test) were used to analyze and compare the temperature variation between coastal (Weihai, Chengshantou and Haiyang meteorological stations were chosen as a representative) and inland (Jinan, Yiyuan and Yanzhou were chosen as a representative) areas based on annual mean data of air temperature from 1959 to 2012 in the Shandong Peninsula. The results showed that the annual mean air temperature increased from 1974 to 2012 both in the coastal and inland area of the peninsular, and they were lower than global level. The change of coast temperature was higher than which of inland by 0.17℃. Further, M-K test analysis indicated that fluctuation range of the coast temperature was lower than that of the inland. In addition, our findings showed that different temporal series (scales) had obviously influence on check result, beta values changed irregular, and Z_c values increased with the temporal series increase, respectively.
