Abstract

Using Landsat ETM + data of Hefei City in July 11th,2002,after the radiometric calibration,atmospheric and emissive correction,inversion of land surface temperature according to mono-window-algorithm,the land classification was carried out.The heat island effect of Hefei City was studied,and the relationship between temperature and land surface parameter was analyzed,and the influence of the urban heat island of city river was discussed.Results showed that the vegetation index to explain the extent of temperature was the best,and the water body had some alleviation effects on urban heat environment.
