城市绿色空间可以通过生态系统服务调节功能有效缓解城市热岛效应,降低高温健康胁迫风险.城市中心城区特别是老城区建成环境具有高度异质性,复杂建成环境中绿色空间的降温效应,特别是混合用地模式中绿色空间的降温强度、阈值、形状等还需进-步明晰.在厘清城市热环境影响因素和绿色空间降温机制基础上,构建了"冷热岛分析提取-混合用地模式聚类识别-混合用地模式热效应分析-典型绿色空间降温效应分析"的研究框架.针对当前城市绿地指标失实、结构失衡、功能失调等现实问题,选择济南市老城区典型片区进行实证研究,重点分析了中层建筑混合用地模式中绿色空间的降温强度、降温面积阈值、形状及植被覆盖度等,总结了具有高降温效能的绿色空间模式,为促进城市健康人居环境发展提供借鉴.
Cooling Effect of Green Space in Typical Areas of Old Urban Area in Jinan Based on Identification of Hybrid Land-use Patterns
Urban green space can effectively mitigate the urban heat island effect and reduce the risk of high-temperature health stress through ecosystem service regulation.The built environment in urban centers,especially in old urban areas is highly heterogeneous,and the cooling effect of green space in complex built environments,especially in mixed land-use patterns,needs to be further clarified in terms of the cooling intensity,the threshold and the shape.On the basis of clarifying the influencing factors of urban thermal environment and the cooling mechanism of green space,the research framework of"heat and cold island analysis and extraction-identification and clustering of mixed land use pattern-analysis of the thermal effect of mixed land-use pattern-analysis of the cooling effect of typical green space"is constructed.Aiming at the current urban green space index misrepresentation,structural imbalance,dysfunction and other realistic problems,a typical area in the old city of Jinan was chosen for empirical study,focusing on the analysis of the cooling intensity of green space in the mixed land-use pattern of mid-rise buildings,the threshold,the shape and the vegetation coverage of the cooling area and summarizing the green space pattern with high cooling efficiency,which provides a reference for promoting the healthy urban living environment.
