摘要
全球气候变暖与城镇化快速发展的综合影响导致了岭南地区夏季升温形势严峻。岭南历史文化街区由于新旧混合的建设现状,密集的建设环境,面临通风不畅、热岛效应严峻的气候环境问题,加强通风是缓解街区夏季高温状况的有效途径。本文选取广州文德路街区作为研究对象,利用流体动力学软件分析街区风环境现状,识别街区通风问题区域,从建筑、街道以及绿地空间三方面提出通风设计策略,并用流体动力学模拟比较改造前后核心空间节点的通风状况,验证通风设计策略的可行性,为岭南历史文化街区保护与更新的气候适应性设计提供参考。
The combined effects of global warming and rapid urbanization have led to a severe summer temperature rise in Lingnan.Due to the current situation of mixed old and new construction and dense construction environment,historical and cultural blocks in Lingnan are facing climate and environmental problems such as poor ventilation and severe heat island effect.Strengthening ventilation is an effective way to alleviate the high temperature in summer.This paper selects the Wende Road block in Guangzhou as the research object,uses fluid dynamics software to analyze the current situation of the wind environment in the block,identifies areas with ventilation problems in the block,proposes ventilation design strategies from the three aspects of buildings,streets,and green spaces,and uses fluid dynamics simulation to compare before and after renovation The ventilation status of the core space nodes verifies the feasibility of the ventilation design strategy and provides a reference for the climate-adaptive design of the protection and renewal of historical and cultural blocks in Lingnan.
