摘　　要：本文以南宁历史城区为研究对象,通过基于多源数据的定量测度方法,描述活力时空变化特征,筛选活力影响因素指标,并构建时空地理加权回归模型,从时间和空间两个维度讨论指标对历史城区活力的影响。回归模型结果显示:街道环境、功能业态和交通可达性对历史城区活力的影响有时空异质性。可步行性、餐饮、文化休闲和生活住宿密度与历史城区活力呈正相关。餐饮、生活住宿、购物、医疗保健密度和距公交站点距离对工作日的活力影响程度更为显著,而在周末,可步行性、天空视率、绿视率和行政办公密度对活力的影响程度更强。最后提出了提升历史城区活力的规划设计启示。Focusing on the historical urban area of Nanning,this study employs a quantitative measurement method based on multi-source data to depict the spatiotemporal characteristics of vitality and to select indicative factors influencing this vitality.A geographically and temporally weighted regression model is constructed to analyze the impacts of these indicators from temporal and spatial di-mensions.The model reveals that the street environment,functional land use,and accessibility significantly influence the historical urban area’s vitality,exhibiting spatio-tem-poral heterogeneity.Factors such as walkability,catering,cultural leisure,and residential amenity density positively correlate with urban vitality.During weekdays,catering,res-idential amenity,shopping,healthcare density,and proxim-ity to public transportation have a more pronounced impact on vitality,while on weekends,the influence of walkability,sky visibility rate,green view ratio,and administrative office density intensifies.The study concludes by proposing plan-ning and design recommendations for enhancing the vitality of historical urban area.
