摘　　要：根据安徽省81个气象台站的资料研究了其气温序列特点,并选取了其中46个台站,划分为城市站、乡村站、国家基本/基准站等类别,对1966～2005年期间平均、最高、最低气温的年、季变化进行了分析比较。结果表明:两个时段各类型台站3项气温的增温率、热岛增温率、热岛增温贡献率均表现为城市站最大,国家基本/基准站次之,乡村站最小。城市热岛对各类型台站年平均气温的贡献率在21.1%～37.8%之间浮动,国家基本/基准台站受其影响较大。城市站和国家基本/基准站的热岛增温率为秋季最大,春季和夏季次之,冬季最小;城市站和国家基本/基准站的热岛增温贡献率夏季最大,秋季次之,冬季和春季略小。因此,安徽省城市热岛效应对城市站和国家基本/基准站气温序列影响较为复杂并不容忽视。Using the data of 81 weather stations of Anhui Province, the characteristics of temperature series were analyzed. The selected 46 stations were classified into urban stations （US）, rural stations（RS）, and basic/reference stations （BS）. The seasonal and annual variations of mean, maximum, and minimum temperatures at the 46 stations were analyzed during 1966-2005. The results show that warming rate of temperature, warming rate of urban heat island （UHI）, and contributive rate of UHI at US, BS, and RS were the maximum, the second, and the minimum, respectively. The contribution rates of UHI effect on annual mean temperature fluctuated from 21＇1% to 37.8%. With the UHI effect on the seasonal warming, the maximum warming rates of UHI at US and BS occurred in autumn, followed by spring and summer, and the minimum occurred in winter; the maximum contributive rates of UHI at US and BS occurred in summer, followed by autumn, and in winter and spring they were a little smaller. It is suggested that the impacts of the variation of UHI intensity on temperature series are complicated and cannot be ignored in Anhui Province.
