As global warming escalates, high-intensity heat waves are increasingly common, raising concerns about their impact on environmental systems and public health. This article focuses on Turpan City, known for having the highest summer temperatures in China, emphasizing its largest transportation hub, Turpan North Station. The study employs field research and data measurement to analyze the local summer climate conditions. Additionally, simulation methods were utilized to assess the spatial and temporal changes in the area’s thermal environment. The research also evaluates six design scenes featuring various configurations of blue-green infrastructure, using the Universal Thermal Climate Index (UTCI) for evaluation. The results show that the average radiation temperature (Tmrt) becomes the primary factor influencing the UTCI. The incorporation of tall trees in varying proportions leads to a substantial reduction in Tmrt, with the greatest decrease amounting to 6.79°C. Furthermore, through the strategic allocation of urban blue-green infrastructure, the UTCI values are decreased by 1.33°C relative to the actual situation and by 1.73°C when compared to simulations lacking blue-green infrastructure. Moreover, the duration of "extreme heat stress" is reduced by a duration of 2 hours. This study also suggests targeted optimization and improvement strategies based on the characteristics of various functional zones surrounding transportation stations. Overall, it provides a robust theo...
