Urban water bodies play a critical role in regulating urban climate, mitigating the heat island effect, and enhancing ecological environments. This study focuses on five typical cities Zhejiang Province, systematically analyzing cooling effects of bodies. Specifically, divides buffer zones into basic analytical units based road network performs land surface temperature inversion use classification using Google Earth Engine platform. Six representative morphology indicators are selected, contributions these to evaluated Gradient Boosting Decision Tree regression model. Additionally, optimization strategies for different proposed. The results show following: (1) Water central areas generally exhibit significant effects, with average reduction exceeding 5.13 °C compared built-up all cities. (2) is higher than that areas, difference at least 0.63 °C. (3) In Huzhou Jiaxing, high-temperature low-temperature relatively concentrated, while Jinhua, Quzhou, Shaoxing, more interspersed distribution observed, reflecting spatial heterogeneity. (4) Among body indicators, edge density, proportion landscape area occupied by patches, largest patch index water, shape exert larger impact effects. These findings provide scientific guidance optimizing layout improving thermal
