气味景观 街道空间品质的一个维度

Urban Smellscape A Dimension of Street Space Quality

街道空间是人们对城市空间进行感知的最基础的内容,城市气味又是衡量街道空间品质的重要方面。尽管如此,由于气味难以被测度与量化分析等原因,城市气味景观至今尚未引起城市研究界的足够关注。文章试将城市气味追踪实验与社交媒体数据相结合,对北京旧城气味进行类别划分,分析旧城范围内的城市气味景观,绘制旧城街道气味地图,并通过社交数据及其语义分析初步检验气味景观地图的可靠性。在此基础上,以后海片区为重点,分析微观层面的城市气味层次以及气味对片区发展的影响。最后,结合研究成果,讨论城市气味景观研究在城市规划与设计中应用的可能性。

Street space is the most fundamental aspect of human＇s perception of urban space. Urban smellscape is also one of the most important measurements of street quality. Nevertheless, most urban studies have overlooked smellscape for several reasons, one of which is that smell is difficult to record and analyze. This paper explores the possibility of combining smellwalking with social media data analysis for classifying city scents and mapping the smellscape of Beijing old city which is later verified with semantic analysis of social media data. Besides, Houhai area is selected as a case study area to show different layers of smells in a small scale and the influence of scents has on places. Eventually, this paper discusses the possibility of employing smellscape in urban planning and design.
