摘　　要：文章利用南京市2017—2022年气象温度数据资料,通过合理选取市区3个自动气象站点和郊区6个自动气象站点,对南京市近年来城市热岛效应进行研究分析。结果表明:南京市城市热岛效应有明显的季节变化和日变化特征,6年间热岛效应呈现先减弱后增强的趋势;整体热岛强度在0.98℃,夏半年明显大于冬半年,夏季热岛强度最大,为1.06℃,冬季最小,为0.86℃;日变化中,20:00热岛最强,为1.55℃,02:00热岛强度为1.52℃,14:00热岛强度最低为0.18℃。The article uses meteorological temperature data from 2017 to 2022 in Nanjing to study and analyze the urban heat island effect in recent years by selecting three automatic meteorological stations in the urban area and six automatic meteorological stations in the suburbs.The results indicate that the urban heat island effect in Nanjing has significant seasonal and daily variations,with a trend of first weakening and then strengthening over the past six years.The overall heat island intensity is 0.98℃,significantly higher in summer than in winter.The heat island intensity is highest in summer at 1.06℃and lowest in winter at 0.86℃.During daily changes,the strongest heat island intensity is at 1.55℃at 20:00,1.52℃at 02:00,and 0.18℃at 14:00.
