<p>Urban parks serve as essential public outdoor spaces, where diverse landscape elements create different landscape spaces, each exerting unique regulatory effects on residents’ thermal comfort. Particularly in severe cold regions, transitional seasons present significant thermal comfort challenges. This study focuses on South Lake Park in Changchun, a city in cold regions, to investigate the relationship between green visibility, microclimate factors, and thermal comfort across different landscape spaces. Field surveys, microclimate measurements, and questionnaires were conducted to analyze the effects of the Sky View Factor (SVF) and Green View Index (GVI) on thermal comfort. The results reveal that the thermal comfort threshold during transitional seasons in Changchun ranges from 16.01&#xa0;°C to 22.68&#xa0;°C, with a neutral temperature of 19.34&#xa0;°C. In square space, SVF and GVI positively influence Physiological Equivalent Temperature (PET), while in waterfront space and sparsely forest space, SVF has a positive effect and GVI has a negative effect on PET. In densely forest space, both SVF and GVI negatively impact PET. The study proposes optimization strategies based on these findings, emphasizing the need for targeted SVF and GVI designs in different landscape spaces to enhance thermal comfort and provide valuable insights for urban planning.</p>

摘要

Urban parks serve as essential public outdoor spaces, where diverse landscape elements create different landscape spaces, each exerting unique regulatory effects on residents’ thermal comfort. Particularly in severe cold regions, transitional seasons present significant thermal comfort challenges. This study focuses on South Lake Park in Changchun, a city in cold regions, to investigate the relationship between green visibility, microclimate factors, and thermal comfort across different landscape spaces. Field surveys, microclimate measurements, and questionnaires were conducted to analyze the effects of the Sky View Factor (SVF) and Green View Index (GVI) on thermal comfort. The results reveal that the thermal comfort threshold during transitional seasons in Changchun ranges from 16.01 °C to 22.68 °C, with a neutral temperature of 19.34 °C. In square space, SVF and GVI positively influence Physiological Equivalent Temperature (PET), while in waterfront space and sparsely forest space, SVF has a positive effect and GVI has a negative effect on PET. In densely forest space, both SVF and GVI negatively impact PET. The study proposes optimization strategies based on these findings, emphasizing the need for targeted SVF and GVI designs in different landscape spaces to enhance thermal comfort and provide valuable insights for urban planning.
