The mean annual temperature data from 1960 to 2012 of Chifeng station that had experienced two times of relocation and the reference stations (three climate observation stations located in the township that had not moved) were used to comparatively analyze the effect of relocation of Chifeng station on the temperature,and then the correction methods were explored. Analysis showed that two times of relocation and the urban heat island effect had made the Chifeng station's temperature difference with reference stations. The mean annual temperature of Chifeng station was significantly higher than reference stations for 53 years. There had five inflection points on Chifeng stationt's temperature anomaly evolution curve compared with reference stations; whereas there had two non-consecutive points just in the two time of relocation; the heat island intensity showed an upward trend over time,the weakest was 0. 26℃ on 1970s,the strongest was 0. 75℃ before the first relocation; heat island intensity was 0. 79℃,and was the strongest before the second relocation; That caused Chifeng station's decadal trends of temperature inconsistent,the climatic warming time and warming abrupt point inconsistent. By using the methods of eliminating Chifeng station's heat island effect and application reference station's temperature to correct the Chifeng station's temperature,we reconstructed temperature series before relocation of the station; using the diagnostic analysis method we tested the new temperature sequence,and the new temperature's climatic trend was consistent with the reference stations,and can be used for business application.
