城市街道多维活力分析模型研究:以广州恩宁路片区为例

A Multidimensional Vitality Analysis Model for Urban Streets:The Case of Enning Road Neighbourhood

在存量规划及公共空间品质日益提升的背景下,历史街区中的各类街道亟需提升活力,目前借助多源大数据量化街道活力并指导设计策略成为学界研究重点。本文梳理利用活力分析模型驱动历史街区街道设计的研究,整合优化其活力测度和活力影响因素指标,从多种活力特征角度构建分析模型。相较现有历史街区语境下各异的活力研究,本分析模型的框架具有通用性和迁移性——适用于不同类型和功能的历史街道且兼顾街道自身形态要素或活力现象的独特性。针对现有模型的活力影响因素对详细设计支撑度不足的问题,综合提出街道活力与影响因素的多对多关系模型,通过相关性分析得出影响因子,导向详细的城市设计要素,在更新策略导出上提供与传统研究方法不同的、动态的研究视角。

Against the backdrop of improving stock planning and public space quality,there is an urgent need to enhance the vitality of various types of streets in historic districts.Currently,leveraging multi-source big data to quantify street vitality and guide design strategies has become a focal point in academic research.This paper reviews research using vitality analysis models to promote street design in historic districts,integrates and optimises vitality measurements and influencing factor indicators,and constructs analytical models from the perspectives of various vitality characteristics.Compared to the diverse vitality studies in existing historic district contexts,the framework of this analysis model exhibits universality and transferability±applicable to different types and functions of historic streets while considering the uniqueness of street morphology elements or vitality phenomena.Addressing the problem of insufficient support for detailed design in existing models,a comprehensive many-to-many relationship model of street vitality and influencing factors is proposed to identify the influencing factors through correlation analysis and guide the detailed urban design elements.This offers a dynamic research perspective distinct from traditional methods for formulating renewal strategies.
