ABSTRACT
With Landsat 8 OLI_TIRS as the remote sensing data source, the ground surface temperature of Changsha was inverted. The information of green space within the third ring-road of Changsha extracted based on the remote sensing data source was combined with the inversion data of the ground surface temperature and the correlation between the landscape pattern indexes and ground surface temperature of the selected green space was analyzed. The research found by increasing the percentage of landscape and the length of the boundary of green space within the third ring-road of Changsha, the cold island effect of green space can be enhanced. Few large green patches have a better cooling effect than a lot of small green patches with an equal total area. The aggregated layout of green spaces in a fixed scope within the third ring-road of Changsha has a better cooling effect than the scattered layout.
