摘要： 为了充分考虑县级城市热岛效应对台站气温序列资料的影响，选取位于淮河中游的不发达县级城镇的台站进行分析，将霍邱国家一般气象站、寿县国家基准气候站（参照站）作为研究对象，基于1965—2010年的平均气温观测资料，采用线性拟合、累积距平等方法，分析了城市热岛效应对霍邱站平均气温序列的影响。结果表明，霍邱站气温资料从1994年开始明显受城市化进程影响。霍邱站1995—2010年热岛效应值介于0.30℃~0.97℃之间；热岛效应强度随年代的推后而呈增强的趋势，并呈现出季节性变化：春季最强盛，秋季次之，冬夏2季最弱。因此，城市热岛效应对淮河中游的县级城市气温序列的影响不容小视。

Abstract: In order to fully consider the influence of urban heat island effect on mean temperature series, the stations which located on the middle reaches of Huaihe River were selected. Huoqiu national meteological observing station and Shouxian national reference climatological stations (reference station ) were choosed as a case study.Based on the average temperature data from 1965 to 2010, the effects of urban heat island on average temperature series of Huoqiu station were analyzed by using linear regression, the cumulative distance equal method. The results showed that the average temperature series of Huoqiu station was obviously affected by urbanization of county-level city since 1994. During 1995-2010, the intensity of urban heat island was 0.30℃-0.97℃. The trend of heat island intensity increased with the lapse of time. The intensity of heat island also presented seasonal variation: the maximum value occurred in spring, followed by autumn, and the minimum occurred in winter and summer. This study suggested that the effects of urban heat island on temperature series should not be ignored in county-level city of the middle reaches of Huaihe River.
