Abstract: This article takes the spatial vitality of Huaihe Road Commercial Block in Hefei city as the research object and defines two evaluation dimensions, including external characteristic elements and constituent elements of spatial vitality. The external characteristic elements are reflected by the data of heat maps. As for the constituent elements, this article presents the corresponding influencing factor indicators in the aspects of the road network configuration, functional commercial form and spatial quality of the commercial block. In addition, it conducts a quantitative study on the multi-source data of the influencing factor indicators relating to the spatial vitality of this commercial block by means of heat maps, block POI, street view images and urban space. In the process of this quantitative study, some tools, such as the ArcGIS platform, space syntax Depthmap modeling and street view semantic analysis, are employed. A quantitative study is further carried out using the correlation analysis method to analyze the relationship between the external characteristic elements and internal constituent elements of spatial vitality of commercial blocks and explore the effects of different factors on the spatial vitality of commercial blocks when these factors are interacting with each other.
