岭南高密度城市高温适应规划设计策略:局地气候分区框架的应用

Heat Adaptive Urban Planning and Design Strategies for High-density Cities in Southern China:The Application of Local Climate Zone Framework

如何通过气候适应性规划设计缓解城市夏季高温状况,构建健康城市,对于我国推进生态文明建设、实现高质量发展至关重要。以岭南高密度城市—广州为例,基于局地气候分区框架分析城市建设形态与土地覆盖特征,构建局地气候分区城市形态分析地图与局地气候分区分类地图,识别城市高温风险热点区域;基于局地气候分区分类地图的高温风险评估结果,选取高温风险街区—文德路街区作为研究对象,从“绿—荫—透—水”4个方面提出岭南高密度城市街区高温适应规划设计策略,并进一步探讨将高温适应规划设计融入国土空间规划体系的路径,以期为我国气候适应规划设计与健康城市建设提供思路与方法参考。

Climate adaptive urban planning and design is critical to ecological,healthy,and high quality urban development.With Guangzhou,a high-density city in southern China,as an example,the urban morphology and land surface conditions based on Local Climate Zone(LCZ)are analyzed,and LCZ urban form analysis map and classification map to identify urban heat areas are established,and a high heat risk area—Wende block is taken as research example,heat adaptive planning strategies from four aspects:greenery,shading,ventilation,and water are proposed.Further,the path of integrating heat adaptive planning with territorial space planning system is discussed,and a reference for climate adaptive planning and healthy urban development is provided.
