By the study of the relationship between vegetation and spatial characteristics of UHI, the mainly spatial characteristics of UHI has been analyzed and it was:(1) The terrain of the suburbs is higher than the urban region, the gradient of the terrain height is small, and this geomorphological featrue is conducive to assemble of the heat, the UHI phenomenon of Changsha is obvious especially in the summer night;(2) The UHI distribution is similar to the outline of the urban construction. The LST of urban is 3-5℃ higher than the flat low areas close around the city, and 6-8℃ higher than further areas.
