摘要:
在气候变化与城市更新转向存量提质的背景下，老旧住区等高密度建成区热暴露问题日益突出，已成为影响居民热舒适感知、健康福祉和人居环境品质的重要因素。城市绿地作为重要生态基础设施，其供给与热暴露之间的空间错配不仅制约热调节服务的有效发挥，而且影响其向居民热舒适感知与健康收益的转化过程，相关作用路径有待进一步厘清。为此，以扬州市为例，整合遥感数据、GIS空间分析和居民问卷调查，识别中心城区绿地供给与热暴露空间错配的重点片区，并进一步分析绿地环境感知、使用行为与居民热舒适感知及健康响应之间的关系。研究结果表明：（1）扬州市中心城区存在典型的“热暴露高—绿地供给弱”空间错配格局，广陵区、江都区等老旧居住区热暴露水平较高而绿地降温能力不足，是城市更新中亟须关注的高温风险治理重点区域；（2）绿地环境感知对居民心理健康具有显著作用，其中景观美感和绿色基础设施质量通过使用意愿发挥中介作用，绿色基础设施质量的路径系数达到0.30（P<0.01）；（3）不同性别与年龄群体在“环境感知—使用行为—健康响应”路径上的作用强度存在显著差异，表明城市绿地热调节服务的居民响应具有明显群体分化特征。可见，城市更新背景下的绿地调控优化应兼顾空间错配识别与居民需求响应，推动绿地配置由一般性增绿转向面向高温风险治理、人居环境修复和健康福祉提升的精准调控。研究结果可为扬州市老旧住区更新中的高温风险治理、绿地系统微更新和气候适应型空间治理提供实证依据，也可为同类城市推进精细化人居环境治理提供参考。
Abstract:
Against the background of climate change and the shift of urban renewal toward the quality improvement of existing built-up areas, heat exposure in high-density built environments such as old residential communities has become increasingly prominent. It has become an important factor affecting residents’ thermal comfort perception, health and well-being, and the quality of human settlements. As important ecological infrastructure, urban green spaces provide thermal regulation services. However, the spatial mismatch between green space supply and heat exposure not only constrains the effectiveness of these services, but also affects their transformation into residents’ thermal comfort perception and health benefits. The related pathways still need further clarification. Taking Yangzhou City as a case study, this paper integrates remote sensing data, GIS-based spatial analysis, and resident questionnaire survey data to identify key areas of spatial mismatch between green space supply and heat exposure in the central urban area. It further examines the relationships among green space environmental perception, usage behavior, residents’ thermal comfort perception, and health responses. The results are as follows. Firstly, a typical spatial mismatch pattern of "high heat exposure-weak green space supply" exists in the central urban area of Yangzhou City. Old residential communities in Guangling District and Jiangdu District show relatively high heat exposure and insufficient cooling capacity of green spaces, making them priority areas for heat risk governance in urban renewal. Secondly, green space environmental perception has a significant effect on residents’ psychological health. Landscape aesthetics and green infrastructure quality play a mediating role through usage intention, and the path coefficient of green infrastructure quality reaches 0.30 (P<0.01). Finally, significant differences are observed among gender and age groups in the "environmental perception-usage behavior-health response" pathway, indicating that residents’ responses to the thermal regulation services of urban green spaces are clearly differentiated across groups. These findings suggest that green space regulation and optimization in the context of urban renewal should consider both spatial mismatch identification and residents’ demand responses. Green space allocation should shift from general greening toward targeted regulation for heat risk governance, human settlement restoration, and health and well-being improvement. The results provide empirical evidence for heat risk governance, green space micro-renewal, and climate-adaptive spatial governance in old residential community renewal in Yangzhou City. They also offer a reference for similar cities to promote refined human settlement governance.
