基于海岛站与附近城市站1972—2012年气温数据，采用线性倾向估计和最小二乘法，研究年际与季节气温变化趋势，分析城市化对气温变化的影响．结果表明：城市站和海岛站年平均气温变化趋势分别为0.29和0.2℃·（10 a ）－1，表明城市化加速了年平均气温升高；年均最低气温、最高气温增温趋势均为城市站大于海岛站，且平均最低气温增温趋势高于最高气温，呈现明显的非对称性；季节变化中，秋季和冬季的增温趋势较大．城市化效应对平均最低气温的影响较对平均最高气温影响显著．
Impact of urbanization on ai r temperatures variation trends based on island stations
Based on temperature data from 1972 to 2012 from island stations and adjacent urban stations ,the variation trends of annual and seasonal air temperature were analyzed by using linear‐trend estimate and the least square methods ,and also analyzed the impact of urbanization on temperature changes . T he results indicated that the annual mean temperature has increased by 0.29 and 0.2 ℃ · (10 a ) -1 at the island and urban stations respectively and urbanization has accelerated the rising of annual average temperature .The trends of annual mean minimum and annual mean maximum air temperatures were more obvious at the urban stations than at the island stations .The warming trends showed that mean minimum temperature was greater than the maximum temperature ,which showed asymmetrical characteristics . In addition , the seasonal temperatures showed increasing trends in winter and autumn were higher than in the summer .The urbanization effect on the mean minimum temperature was more significant than mean maximum temperatures .
