A Study Oil Thermal Environment of Urban Group in Yangtze River Delta
Changes in the urban thermal environment of the Yangtze River Delta are studied based on the two scenes of MODIS land surface temperamre(LST)data from October 8th to 15th in 2001 and 2005,and the time-space patterns of thermal landscape are quantitatively analyzed using knowledge of landscape ecology in conjunction with the GIS technique.Finally the research indicates that there was a group of urban heat islands composed of Shanghai,Suzhou,Wuxi and Changzhou in the delta in the past five years.The UHIs have been under control effectively in some cities of the Yangtze River Delta due to rational city programming and protecting environment.
