In this study,by using monthly mean temperatures derived from 17 uniformly distributed meteorological stations since foundation,the regional mean temperature anomalies were reconstructed after filling gaps on basis of linear regression method. Furthermore,the temperature variations,warming rates,periodicity,as well as time of abrupt change were as well analyzed by using statistical,power spectrum analysis,and Mann - Kendall testing methods. The relationship between temperature series of global,hemispheric,China and Henan were also studied. The results showed that:(1) The regional mean temperatures presented a significantly warming trend during the period 1951 - 2015. The linear trend for this period amounted to 0.18 0.06℃ per decade. The average amplitude of inter - annual variability were 0.46 0.07℃. All confidence ranges mentioned above were calculated at the 95% confidence level and were statistically significant.(2) On decadal time scale,the climate were relatively colder during the 1950s and 1980s. From 1960s onwards,regional temperature anomalies fluctuated remarkably around 0℃ till the end of the 1970s. However,annual temperatures increased dramatically since the 1990s. Significant periodicity of 2.3a and 3.8a were detected over the past 65 years,with abrupt temperature change occurred in 1994.(3) Comparisons of temperature changes of Henan with global,hemispheric and entire China indicated similar cold /warm periods. The warming rate,periodicity,as well as time points of abrupt change were consistent between different spatial scales,but the amplitude of fluctuations and inter - annual variations were larger in Henan regional temperature compared with the other three series.
