Abstract

With the rapid urbanization, problems caused by heat-island effect have become more and more serious. It is necessary to make rapid and effective monitoring of the distribution of heat islands in cities. In this paper, the Landsat7 ETM+ image of Nanjing was investigated as an example. A correlation model was built between ground temperature and image brightness of TM6, and in this way， the distribution of temperatures in Nanjing was obtained. The urban vegetation can be classified into forest, interspersed tree and herbaceous plant based on the NDVI value. At the same time, the other ground objects can be classified by supervised classification. In addition, the authors probed into the correlation coefficient between the ground covers and the temperature distribution from the angle of fragmentation degree. It can be concluded that different fragmentation degrees of urban greening exert different effects on the temperature of ground surface.
