Investigating the urban heat island (UHI) effect across different seasons can reveal impact of seasonal temperature changes on environment, improve living standard, and develop feasible measures to mitigate UHI effects. In study, land surface (LST) summer winter was quantitatively retrieved in a megacity (Shenzhen city) during 2013-2023. Through standard deviation ellipse, profile analysis GeoDetector model, this study systematically analyzed spatial-temporal evolution characteristics driving factors thermal environment winter. The results showed that LST initially decreased then increased from 2013 2023, while consistently increased. During area decreased, whereas green land, wetland, natural open water were lower than cropland, unvegetated artificial surface, demonstrating vegetation had mitigating UHI. Land cover type interactions with normalized difference built-up index (summer) PM2.5 (winter) have most significant influence This could provide scientific references for rational planning sustainable development.
