摘要:
In this paper, according to atmospheric observation data, atmospheric correction was firstly done by MODTRAN software to thermal-infrared images of Landsat-TM in 1997 and 2004 in Beijing. Then on the basis of atmospheric correction, a single-window algorithm was used to retrieve the land surface temperature (LST) of urban district and its surrounding area with the help of RS and GIS technology. The results showed that there was a clear urban heat island (UHI) in Beijing, and the LST of urban center was higher than that of suburb area. In addition, there was a clear intensification trend of UHI and the factitious impacts produced a more contribution to UHI in Beijing with the quick expansion of urban area and urban population.
