摘要

As global warming leads to more frequent extreme weather events, high temperatures significantly impact the comfort of transportation facilities such as high-speed railway stations. This study aimed to explore effective landscape design strategies to reduce summer temperatures in traffic plazas and to evaluate the interaction between greenery layouts and near-surface microclimates. Using the Chongqing East Railway Station as a case study, three typical spaces were selected, and ENVI-met simulations were conducted to analyze the impact of different landscape layouts and green coverage rates on thermal comfort. The results indicated that the new landscape configuration effectively reduces extreme summer temperatures, with reductions of approximately 0.41 ℃ and 0.39 ℃ in maximum and minimum air temperatures, respectively. The simulation results of this study not only validated the effectiveness of the design strategies discussed in this study in addressing extreme summer climatic conditions but also provided important design foundations for enhancing the thermal comfort of urban transportation plazas and their adaptability to climate change. These findings further underscore the potential value of applying these strategies in urban planning and design.
