Abstract:15 Landsat-8 OLI/TIRS and Landsat-5 TM images from 1995 to 2019 were used to retrieve the land surface temperature in Guangzhou by atmospheric correction and mono-window algorithm. According to the spatiotemporal analysis of the results, from 1995 to 2019, the area of Guangzhou's heat island began to be in a stable stage, then it showed a rapid growth trend from 2001 to 2014, and then decreased at a slow rate after 2014. The results show that the areas where the heat island effect has been alleviated are old urban areas, and the reasons for the change may be related to the relocation of industrial areas and the improvement of greening. The spatial distribution pattern of heat islands was agglomerated from the center, gradually spreading to the north-south direction and the east direction, and then evolved into a strip-shaped dominant, multi-center spatial distribution characteristic. Its changing trend was basically consistent with the urban development mode.
Keywords:heat island  temperature retrieval  Guangzhou  Landsat
