Relationship between urban spatial form and seasonal land surface temperature under different grid scales

·Land surface temperature (LST) was similar in spring and autumn and was significantly lower in winter.·Urban spatial form (USF) indicators influence seasonal LST, and their correlation is significantly lower in autumn.·The three most important USF indicators for LST in spring and winter were SHDI, NL, and BMH, and their importance changed according to different scales.·By controlling urban building morphology of USF could effectively improve the urban thermal environment.
