Amidst the rapid global urbanization and economic integration, coastal cities have undergone significant changes in urban spatial patterns. These further worsened complex thermal environment, making it crucial to study interaction between human-driven development natural climate systems. To address insufficient quantification of marine elements planning subtropical zones, this takes Xiamen, a typical deep-water port city, as an example construct analysis framework integrating boundary layer parameters. This research employs interpolation simulation, atmospheric correction, other techniques simulate inversion land use Landsat 8 data, deriving morphological Land Surface Temperature (LST) data. data were then assigned 500 m grids for analysis. A bivariate auto-correlation model was applied examine relationship carbon emission LST. The area categorized based on influence factors, relationships LST analyzed using multiscale geographically weighted regression model. Three Xiamen-specific discoveries emerged: (1) exerts mitigation effect with average range 7.94 km; (2) morphology environment exhibits notable heterogeneity across different regions; (3) mitigate environments, connected green corridors should be established southern areas outer districts regions significantly influenced by ocean. In less influence, complexity introduced disrupting relatively intact blue–green spaces, while unaffected ocean focus increasing spaces reducing impervious surfaces water bodies. findings directly inform Xiamen’s 2035 Master Plan combating heat island effects special providing transferable metrics similar maritime cities.
