Abstract In arid regions with limited water resources, numerous reservoirs have been built to support economic and social development. However, how the construction of interacts surrounding ecosystem affect temperature remains unclear. Spanning 2018 2022 in Shiyang River Basin, we collected surface precipitation, as well stem soil samples. Using isotopic methods, quantified evaporation oasis reservoir‐riparian forest system affects local climate. Our findings show that latent heat released by evapotranspiration from reservoir riparian reduces daily maximum range 7°C 6°C respectively, compared downstream areas sparse vegetation around artificial lakes. Additionally, it enhances moisture recycling, increasing precipitation. This study reveals regional cooling effect due interactions between bodies, atmosphere, vegetation. We propose establishing systems can positively impact climate regulation serve an effective strategy for adapting global warming.
