Abstract :
Urban heat island (UHI) effect is one of features in the modern city. The land surface temperature of study area was retrieved from ETM+ data via generalized single-channel algorithm, and two urban corridor structures-the greenbelt system and water system were extracted by the GIS to investigate their relationship with Nanjing UHI. The results showed that the two corridor structures both have an obvious effect on Nanjing UHI in the summer. The cooling effect of the greenbelt system is more obvious than that of the water system. Moreover, the impacting range of the two corridor structures is limited and usually not exceeding 240 meters from the water system and 300 meters from green system.
