Abstract

With the rapid development of urbanization,urban heat island has a trend of enlargement.Based on GIS data and Landsat-7 ETM+ images,the thermal infrared and multi-spectral remote sensing data have been delt with and translated.,then the relationship between land use pattern and heat island effect has been analyzed.The results indicate that the heat island can change depanding on concertration of urban space.The style of land use/land cover is the main factor.The intensity of heat island from high to low is industrial area,city center(business district),residential area and suburban area.
