摘要
倡导并践行绿色、低碳、健康的可持续城市设计理念是实现“碳达峰、碳中和”国家战略和缓解全球气候压力的重要举措。本文将分形几何理论融入微热环境下街区形态研究,创建面向复杂街区空间形态研究的非线性分形几何模型,拓展了城市复杂街区空间形态研究的理论视野与内涵。通过对微热环境下街区空间形态理论构建和测度方法解析研究,确定并阐释分形解析空间结构的关键指标概念,进而选择南京新街口街区作为典型样本,运用形态测度和微热环境的模拟方法,探索整体指标和单一指标对街区微热环境的影响规律与作用机制,以科学方法探索缓解城市热岛效应,提升城区气候舒适性的途径,对当代绿色、低碳、健康的可持续性城市设计及街区规划提供设计参考和评估指导。
Promoting and practicing green,low-carbon and healthy sustainable urban design is an important step towards achieving the national strategy of“carbon peaking and carbon neutrality”and alleviating global climate pressure.In this paper,the fractal geometry theory was integrated into the study of block form under microthermal environment,to create a nonlinear fractal geometric model for the study of complex block form,which expanded the theoretical vision and connotation of research on the spatial form of urban complex blocks.Through the theoretical construction and measurement of the spatial form of blocks under microthermal environment,key indicators for the fractal analysis of spatial structure were identified and explained.Then,the study selected the Xinjiekou block in Nanjing as a typical sample and delved into the laws and mechanisms of all indicators and single indicators on the microthermal environment of the block with the morphological measurement and simulation methods of the microthermal environment to explore a scientific approach to mitigate the urban heat island effect and enhance the climate comfort of urban areas.The study can provide design reference and assessment guidance for green,lowcarbon and healthy sustainable urban design and block planning.
