摘要
随着城市可持续发展及城市品质提升的关注,旨在缓解城市热岛效应的通风廊道构建成为研究热点。结合城市气候知识、地理信息技术及城市空间模型,以衡阳县为例,在城市通风路径研究的基础上,探索基于城市道路气流特征及绿地空间布局优化的城市广义通风廊道构建的基本思路,并依托FLUENT数字模拟平台,多尺度评估分析通风廊道设计方案,反馈于广义通风廊道的规划设计,提出相应的空间规划策略和管控措施,为城市广义通风廊道研究提供思路。
With the concern of urban sustainable development and urban quality improvement,the construction of ventilation corridors to alleviate the urban heat island effect has become a research hotspot.Combined with urban climate knowledge,geographic information technology and urban space model,taking Hengyang county as an example,on the basis of urban ventilation path research,the objective of this paper is to explorethe basic ideas of constructing urban generalized ventilation corridor based on urban road airflow characteristics and green space layout optimization.Relying on the FLUENT digital simulation platform,this paper carried out multi-scale evaluation and analysis of ventilation corridor design scheme,which feeds back to the planning and design of generalized ventilation corridor,and proposed corresponding spatial planning strategies and control measures to provide ideas for the research of urban generalized ventilation corridor.
