城市建成环境气候韧性的空间测度

Spatial Quantification of Urban Climate Resilience

如何增强城市建成环境对极端气候事件的韧性,已成为城市规划与管治的关注焦点。基于该背景,本研究以极端气候事件为例,基于多源数据,探究城市建成环境气候韧性的空间测度方法并将其用于极端高温事件。研究发现,建成环境密度并非气候韧性的决定性因素,低效绿化亦可导致建成环境对极端高温的韧性较低。研究成果对进一步量化城市建成环境气候韧性的空间分异与归因,以及拓展气候变化背景下的城乡规划理论具备重要意义。

Enhancing the resilience of the urban built environment to extreme climate events at the urban scale has become the focus of urban planning and governance.Using extreme heat events as an example,this paper explores the spatial quantification method for the climate resilience of the urban built environment based on multi-source data.We find that building density is not a determining factor of climate resilience,and that inefficient greening also leads to lower heat resilience of the built environment.The research findings are important for further analysing the spatial differentiation of the climate resilience of the urban built environment and improving the urban and rural planning theory in the context of climate change.
