Effects of Open Space Characteristics on Microclimate in Railway Station Areas in Hot Summer and Cold Winter Regions: Case Studies of Chengdu East Railway Station and Chengdu South Railway Station
Abstract：As an urban gateway and climate-sensitive area, railway passenger station areas have gradually transitioned from the urban periphery to the urban core with urban development, bringing increasing negative impacts to the city. This study examines the spatial and microclimatic characteristics of two distinct station areas: a large-scale, low-density Chengdu East Railway Station area and a small-scale, high-density Chengdu South Railway Station area. The analysis delves into the relationship between the spatial form of these areas and their microclimatic variables. The results show that the microclimate changes in open space are more obvious in winter than in summer. The distance from the vertical line to the stock channel has a significant effect on the microclimate variables within the station areas, with larger the stock channel areas exhibiting stronger effects. In summer, the correlation between green space area and the quantity is stronger in the East Station than in the South Station. At the same time, street ratio, orientation, and SVF have no significant effect on the microclimate of the East Station, but are key drivers of the microclimate change of the South station. Based on these findings, the study identifies and analyzes the organizational characteristics of spatial elements that contribute to better microclimatic performance. These insights provided inspiration for the future development and planning of climate-adaptive station areas in hot summer and cold winter regions.
