Abstract
In this paper, three towns of Wuhan are used as the research object, and Landsat TM in 09/2009 is use d as the main remote sensing data sources. Based on the land surface temperature interpretation after the processin g of image correction, the urban construction index NDBI and normalized difference vegetation index NDVI were calculated in the study area, meanwhile, the surface emissivity was counted by NDVI index and the single window algorithm was used to calculate the surface temperature in the summer of 2009 LST in the study region. The resea rch results show that the urban heat island in the summer of Wuhan consisted of three heat islands in Wuchang,Ha nkou and Hanyang city area, and there existed some more serious "island to island" of heat effect in the border ar ea of three towns, while it was more focus on the commercial center of Hankou. Further research on the relations hip of LST, NDVI and NDBI in the vegetation area and construction area showed that, there was a bigger differen ce in different land cover types of LST and NDVI, NDBI index: Correlation study shows there was a in positive correlation between city LST and NDBI index, and correlation coefficient of construction land>vegetation>water bod y.There was a negative correlation between city LST and NDVI index with the correlation coefficient of urban lan d>vegetation, while LST of water body existed positive correlation with NDVI index.关键词
