Based on the data of annual mean temperature at Chifeng of Inner Mongolia and su rrounding 3 me teorological stations from 1959 to 2007, a contrast analysis is made concerning the influence of the heat island effect and move of Chifeng Station on temperatu re measurements. Results show that th e Chifeng Station has been affected by heat island effect, and annual mean temp e rature in Chifeng increased about 0.7℃ by heat island effect. The heat island i nt ensity was also increasing，and its warming rate was 0.29℃／10a． After st ation moving, the heat island effect disappeared, and the i ncreasing t emperature range in Chifeng becomes smaller, thus temperature changing trend see ms incont inuous,and the remarkable jump point of the abrupt climatic change is also chang ed.
