Construction of urban ventilation corridor scheme from the perspective of heat risk
摘要
Abstract
The rapid urbanization since the 21st century has brought about many climate and environmental problems.As an effective mitigation means,the rational construction of urban ventilation corridor has attracted deep attention.From the perspective of urban heat risk,this paper connects the function space,compensation space and potential corridor space of Wuhan urban development area based on the circuit model,and constructs the urban ventilation corridor scheme under the scale of urban development area.The conclusions are as follows:the heat exposure index in Wuhan urban development area shows an increasing trend from 2013 to 2023,while the spatial distribution of heat adaptation index and heat sensitivity index present a central high and low peripheral structure.The areas with high and relatively high heat risk in Wuhan urban development area are mainly distributed in the western and northeast areas,and Jianghan District,Qiaokou District,Qingshan District,Jiangan District need to be focused on.The ventilation potential in the urban development area of Wuhan is distributed in a circle type,decreasing successively from the core area of the second ring road.Six urban ventilation corridors are planned for the urban development area of Wuhan city,four of which conform to the southwest wind direction and two conform to the southeast wind direction.Compared with the previous construction path,the ventilation corridor construction method proposed in this paper has a more comprehensive perspective and more targeted technical characteristics.The research results expand the theoretical framework of the research on urban ventilation corridors,and can provide scientific guidance for the planning of ventilation corridors in Wuhan and the cities experiencing similar high heat risks.关键词
