Abstract: Based on the QuickBird, Landsat/TM images, and GIS spatial analysis techniques, the urban land use information, land surface temperature (LST), and normalized difference vegetation index (NDVI) in Shenyang City were obtained, and the differences of and spatial relationships between the LST and NDVI for different urban land use types in the City were quantitatively analyzed. There was an obvious reverse variation trend between the LST and NDVI, and the mean LST and NDVI values differed significantly with land use type. Multiple comparisons showed that the mean LST and NDVI values of pairs of each land use type also had significant differences, and the correlation between LST and NDVI was significantly affected by the scale of spatial resolution, being increased first, decreased then, and increased again with increasing spatial scale. This study could provide scientific basis for mitigating urban heat island effect in urban planning and urban green space system planning.
