摘要
This study examines the impact of different types and processes of urban renewal on the urban heat island (UHI) effect. The research categorizes renewal projects based on changes in buildings, underlying surfaces, and functions. Using the Spearman correlation coefficient and LOWESS method, the study analyzes the relationships between cooling effects and impact factors. The results reveal that transforming industrial areas into commercial or residential zones and transitioning from compact mid-rise to open high-rise structures have significant cooling effects. However, the renewal implementation of the latter transformation can exacerbate the local UHI, suggesting the need for optimizing the timeline of such projects. Increasing vegetation cover plays a crucial role in mitigating the UHI, while higher floor area ratios and building volumes do not necessarily intensify the UHI. To improve the urban ecosystem, urban renewal planning should prioritize the creation of blue and green spaces, incorporation of natural infrastructure, and reduction of impervious surfaces. These findings have implications for urban renewal policies, selection of preferred renewal types, and insights into the renewal process.
