【摘要】 针对现今居住环境空气质量日益下降及呼吸道传染病流行的状况,本研究主要采取CFD模拟的方法,运用空气龄作为评价指标,研究居住区内常见绿地的布局形式对空气质量的影响。研究发现,开敞边界比四周围合型中心绿地的空气龄低,尤其是对角型布置易形成风廊,有利于空气流通;宅间绿地空气龄状况受建筑影响较大,绿化布局避免和建筑形成包围结构,可结合入户道路种植创造风廊,降低空气龄。更多还原

【Abstract】 Given the declining air quality of the living environment and the prevalence of respiratory infectious diseases,this study mainly adopts CFD simulation method and uses air age as evaluation index to study the impact of different layout forms of green space on space wind environment in the residential area.The results show that the lower the wind speed is,the pollutants are easy to deposit,and the number of air age is larger.The air age of the central green space with open boundary is lower than that of the surrounding central green area,especially the diagonal layout type,which is easy to form a wind corridor for air circulation.The air age of the green space between houses is greatly affected by the buildings,and the surrounding structure should not enclose the greening.The greening can be added into residence entrance planting,creating a wind corridor and reducing air age.更多还原
