摘要: 以山东省青岛市历史文化街区为例，借助多源数据，利用ArcGIS中核密度分析、自然间断法等对街区空间活力及其影响因素进行量化，并利用SPSS平台将两者进行相关性分析，探究开发强度、交通可达性、功能多样性和历史资源聚集度4个指标对空间活力的影响。研究发现，历史文化街区空间活力在时间上呈现工作日大于休息日、在空间上呈现西高东低的特点。在相关性方面，开发强度和功能多样性对空间活力的影响更显著，其次是交通可达性中的路网密度因子和历史资源聚集度，而站点覆盖率因子的相关性较弱。结合相关性分析结果和街区特点，提出公共空间营造、交通组织优化、功能定位明确、历史遗产资源活化等街区更新策略，为历史文化街区空间活力提升提供科学引导。
Abstract: Taking the Historical and Cultural District of Qingdao as an example, with the help of multi-source data, this paper quantifiesthe spatial vitality and its influencing factors by using the kernel density analysis and natural discontinuity method in ArcGIS,and analyzes the correlation by using the SPSS platform. The paper explores the impacts of development intensity, traffic accessibility, functional diversity and historical resource aggregation on spatial vitality. The study finds that the spatial vitality of historical and cultural blocks is greater on workdays than on weekends, and spatially higher in the west of the city than in the east. In terms of correlation, the impacts of development intensity and functional diversity on spatial vitality are more significant, followed by the road network density and historical resource aggregation degree, while station coverage is less correlated. Combined with the results of correlation analysis and the characteristics of blocks, this paper puts forward several block renewal strategies, such as public space construction, traffic organization optimization, clear functional positioning, and activation of historical heritage resources, so as to provide scientific guidance for the promotion of spatial vitality of historical and cultural blocks.
