摘 要: 城市化使得城市数量和规模不断增加,其中城市内部温度显著高于周边郊区的热岛效应是城市气候的典型特征之一。南京市江宁区正处于工业化与城市化快速发展的时期,近年来城市扩张速度较快,城市热岛效应明显。应用两个时相的Landsat TM 和ETM+数据,对江宁区进行城市扩张和城市热岛提取,并对两者关系进行分析。结果表明:不同地物覆盖对地表温度的影响一样,植被与地表温度呈负相关,城市化使得热岛效应进一步加剧。
关 键 词: 摄影测量与遥感技术;城市扩张;城市热岛;亮温

Abstract: Urbanization make the increasing number and scale of city. Urban heat island effect is the internal temperature was significantly higher than the surrounding suburbs, which is the typical characteristic of city climate. Jiangning district of Nanjing is in a rapid industrialization and urbanization development period, the fast urban expansion in recent years, urban heat island effect significantly. In this paper, the Jiangning district for urban expansion and urban heat island extraction and analysis of their relationship by two temporal Landsat TM and ETM + data. The results show that the different features coverage of the impact of the same surface temperature, vegetation and the temperature was negatively correlated, urban heat island effect of making further intensified.
Key words: photogrammetry and remote sensing; urban expansion; urban heat island; brightness temperature
