Urban Heat Island Effect Study and Pridiction Analysis Based on Landsat TM Data

Recently,along with the fast-developing urban construction,the urban heat effect(UHI) has caught great attention.Using the Landsat TM images which were obtained on 1999,2005 and 2009,the evolution of the urban heat island distribution in Dongying city are analyzed and future tendency of urban heat island are predicted,following the Markov Model in this paper.The result showed that the UHI in Dongying city was obvious and existed steadily,the centers of UHI present to the Xicheng district,Dongcheng district,which are all the densely inhabited district and industrial park gathering,vegetation and water have reduced the role of heat island effect with the developing of urban expanding,the distributing of heat island become wide,besides the distributing show a small and wide.With the urban pay more attention to environmental governace and urban greening,the trend of Dongying heat island effect has weakened in the next decade,but the speed is slow.
