    • Abstract
  • The thermal infrared data of landsat thematic mapper imagery is used to study the time and space distribution of the heat island of Wuhan between 1988 to 2002.Remote sensing methods and BP neural network are combined to dynamically simulate the land surface temperature of Hankou when the land surface structure of the city changed;the change of the heat-island when the vegetation increase of the city,is analyzed emphatically.The result indicates that,from 1988 to 2002,the urban heat island effect has noticeably increased.The increasing green area can decrease the scope and the intensity of local urban heat island.The larger the area of vegetation is,the wider relaxation of the urban heat-island effect is,and the stronger its relaxation power is.
