摘要: 以常州市区为研究区域,运用“单窗算法”对TM卫星第6波段进行解译,得到卫星过境时常州市区的地表温度(LST)分布图。结果表明:2006年9月18日卫星过境时常州市城区地表平均温度的热岛强度为3.81 K;常州热岛效应的空间分布特征为“一个片区结合多个组团”,与城市的发展格局基本一致,表明城市化引起的土地利用/土地覆盖变化是形成热岛效应的主要原因;城市工业用地的地表平均温度极显著高于城区,表明工业生产消耗大量能源而产生的人为热对常州市热岛效应的形成以及热岛强度的增强具有显著影响。

Abstract: To study the heat island effect in urban area of Changzhou City, a land surface temperature (LST) image was established by using mono-window algorithm to interpret the 6th band of Landsat TM. On September 18th 2006, the day the Landsat TM passed through Changzhou, the heat island intensity of the mean LST in Changzhou urban area was 3.81 K. The spatial distribution pattern of heat island effect in Changzhou could be described as a one piece area in addition to several decentralized associated groups, being consistent with the current urban development pattern, which suggested that the land use/cover change and anthropogenic heat emission induced by urbanization would be considered responsible for the formation of heat island effect. The mean LST of industrial land was significantly higher than that of non-industrial land, which indicated that the anthropogenic heat produced by industrial production had evident effects on the formation of heat island effect and the increase of heat island intensity.
