建筑与绿地结合的居住区灰霾污染改善策略

The Residential District Planning and Design Optimization under Gray Haze Weather Conditions

普遍而严重的灰霾对我国城市居民的身心健康造成了巨大影响,并呈加重之趋势。居住区是市民主要居住与生活的场所,其灰霾污染主要来源之一是机动车尾气。该文介绍了灰霾天气条件下居住区灰霾污染的主要来源、形成与扩散机制。指出灰霾在城市较小尺度上普遍存在着分布不均匀现象。利用这种灰霾分布的不均匀现象,从建筑与绿地结合的角度进行居住区总体布局、细部设计等改善环境的若干策略,并在污染源的控制与引导,开放空间设计与绿地结合,绿地的规模化与整体化以及居住区地下车库机动车尾气有组织排放等方面结合实例进行了分析。

With the urbanization process, China＇s gray haze pollution is more and more serious, caused the living healthy declining, this trend will not change in the near future. The residential area is the main place of living and the life, the motor vehicle exhaust in residential areas caused air pollution. This paper introduces the grey haze pollution, the major source of dust haze of the proliferation of channels, etc. It points out that the grey haze in a small area of the city is generally not uniform distribution of the phenomenon. Using this uneven distribution phenomenon, analyzing the residential district planning and design, the building layout and the green design and integrate the pollution control in residential area, open space and green space combination, the motor vehicte parking and road and gray haze control combination, it is possible to find new residential area planning and design method, so as to reduce the gray haze of the residential area.
