【摘要】：街道空间作为城市重要的公共空间,街道中的空气质量对行人的健康有明显的影响。研究表明街道空间形态是街道空气质量的至关重要的影响要素。但是街道峡谷的空气质量研究模型主要还是基于早期欧洲的古典街道,这与经历过现代主义的街道空间形态相去甚远。因此,对当今城市的街道空间进行总结与分类,并展开其与空气质量的关系的研究至关重要。本文基于以上的研究背景,尝试对南京城市街道空间与空气质量的相关关系进行讨论与研究,为将来的城市设计做出一些参考与建议。在街道空气质量研究中,本文选取空气龄作为评价标准,基于空气龄对街道空间形态进行分析与总结。首先,本文在梳理了南京整体的街道特征基础上,通过实验模拟与验证,在CFD平台下建立起可以表征南京城市街道的标准模型。在此基础上,将街道空间分为居住建筑街道与公共建筑街道两大类进行总结与模拟。对于居住建筑街道,对其沿街建筑类型进行总结与分类,并以此为基础设置模型进行模拟,讨论街道空间与空气质量的关系。对于公共建筑街道,对单个空间的进行总结,在此基础上建立实验模型,以此来讨论街道空间形态对附近街道的通风的影响。最后选取5条真实的街道进行模拟验证,初步对街道空间特征与街道整体的空气龄的关系做出总结,基于空气龄提出相应的街道空间设计策略。同时,对今后基于微气候的街道空间形态研究提出展望与建议。
[Abstract]:Street space as an important public space in the city, the air quality in the street has a significant impact on the health of pedestrians. The research shows that street space form is the most important influence factor of street air quality. But the air quality model of street canyons is mainly based on the classical streets of early Europe, which is far from the street space form that has experienced modernism. Therefore, it is very important to summarize and classify the street space and study the relationship between street space and air quality. Based on the above research background, this paper attempts to discuss and study the relationship between urban street space and air quality in Nanjing, and make some references and suggestions for future urban design. In the study of street air quality, this paper selects air age as the evaluation standard, and analyzes and summarizes the street space form based on air age. First of all, on the basis of combing the whole street characteristics of Nanjing, through the experimental simulation and verification, the standard model which can represent Nanjing city street is established under the CFD platform. On this basis, the street space is divided into residential building street and public building street for summary and simulation. For residential building streets, the types of buildings along the street are summarized and classified, and based on these models, the relationship between street space and air quality is discussed. Based on the summary of a single space for public building streets, an experimental model is established to discuss the influence of street space form on the ventilation of nearby streets. Finally, five real streets are selected for simulation and verification, and the relationship between street space characteristics and the overall air age of the street is summarized, and the corresponding street space design strategy is put forward based on the air age. At the same time, the future research on street spatial morphology based on microclimate is proposed.
