Abstract：Taking Wuhan, a water network city, as an example, this study aims to discuss the role of climate regulation influence between cities and water bodies, and to find ecological spatial regulation strategies to cope with high-intensity urban development and improve the urban climate environment. In this paper, a high-resolution urban canopy model (NUDAPT) is constructed in a mesoscale meteorological model (WRF) to simulate and analyse the microclimatic regulating effect of water bodies in different seasons. It finds that water bodies have a significant cooling effect on urban areas in summer, with an average daytime cooling of 0.5℃. In autumn, the water bodies increase the surface temperature before sunrise by 0.6℃, which can effectively mitigate the radiation inversion phenomenon. At night in winter the water bodies raise the wind speed in the main urban area by 0.2 m/s, which can help evacuate urban air pollutants and reduce the haze phenomenon. Besides, it finds that increased building density enhances convective heat exchange between water bodies and high altitudes, while increased urban volume ratio weakens the cooling effect of water bodies.
