Abstract:
Land surface temperature of Beijing city was retrieved based on the TM imagery data acquired on May 6th 2005 with the generalized single-channel algorithm. The characteristics of the thermal environment and the distribution of the urban heat island of Beijing city were addressed. The relationships between topographic fac- tors, various land cover types and the land surface temperature were analyzed using GIS spatial analysis tools. The results show that the urban heat island area of Beijing city is strip-shaped and ring-shaped. Lower elevation and smaller slope are favorable to form the urban heat island, and the various land cover types have dramatically different thermal properties.
