摘　　要：选取赤峰站和周围3个站1959—2007年年平均气温资料,分析了热岛效应和迁址对赤峰站温度的影响。结果认为,迁址前赤峰站受到了城市热岛效应的影响,热岛效应使得赤峰站平均温度上升了0.7℃。热岛效应强度呈增强的趋势,增温率为0.29℃/10年。迁址后热岛效应消失,升温幅度减小,使得温度变化趋势出现了不连续现象,同时导致了气候变暖突变点的变化。Based on the data of annual mean temperature at Chifeng of Inner Mongolia and surrounding 3 meteorological stations from 1959 to 2007,a contrast analysis is made concerning the influence of the heat island effect and move of Chifeng Station on temperature measurements.Results show that the Chifeng Station has been affected by heat island effect,and annual mean temperature in Chifeng increased about 0.7℃ by heat island effect.The heat island intensity was also increasing,and its warming rate was 0.29℃/10a.After station moving,the heat island effect disappeared,and the increasing temperature range in Chifeng becomes smaller,thus temperature changing trend seems incontinuous,and the remarkable jump point of the abrupt climatic change is also changed.
