Digital Analysis and Design for Historical and Cultural Districts from the Perspective of Spatiotemporal Vitality: Using Hangzhou Qiaoxi District as the Case

Abstract

The protection and renewal of historical and cultural districts are receiving increasing attention. Nevertheless, many districts experience substantial gaps in vitality between day and night, while existing research rarely considers vitality assessment across multiple temporal dimensions. In response, this study proposes a digital analysis and design method for historical and cultural districts from the perspective of spatiotemporal vitality. Key evaluation dimensions are extracted by integrating classic theories of urban design and spatial vitality, then quantitatively analyzed to identify areas with insufficient vitality and support targeted strategies and design. Multi-source data make it possible to assess the continuation of spatiotemporal vitality and the enhancement of spatial richness. The study explores relationships among spatial vitality, functional characteristics, and spatial perception under spatiotemporal dynamics. It establishes a method for evaluating design effectiveness and provides embedded support from baseline analysis through design intervention and post-design evaluation.
