街道公共空间安全视角下城市更新研究

Research on Urban Renewal from the Perspective of Street Public Space Security

街道公共空间是城市重要的组成部分,也是人类行为发生的重要场所。本文以街道公共空间为切入点,从社会安全需求、犯罪机会风险视角出发,选取北京市丰台区方庄为研究对象,探讨公共空间设计与安全感知的关系。利用ArcGIS、Depthmap等方法对街道公共空间进行研究分析,通过李克特量表及SPSS等方法进行心理安全感知调查,确定空间位置属性、形态属性、氛围属性等相关指标对宏观、微观街道空间安全的影响。本研究提出激活街道降低客观犯罪机会风险、促进公众参与提升主观心理安全感知的双向动态促进机制,为安全视角下街道公共空间更新设计提供了参考。

Street public space is an important part of the city,but also an important place for human behavior.This paper takes street public space as the entry point,from the per-spective of social security needs and crime opportunities and risks,and selects Fangzhuang,Fengtai District,Beijing,as the research object to discuss the relationship between public space design and security perception.ArcGIS,Depth map and other methods were used to study and analyze the street public space,and Richter Scale and SPSS were used to investigate the psychological security perception,so as to determine the impact of spatial location attributes,morphological attributes,atmosphere attributes and other related indicators on macro and micro street space secu-rity.This study proposes a bidirectional dynamic promotion mechanism to activate streets to reduce the opportunity and risk of objective crime and promote public participation to enhance subjective psychological security perception,which provides a reference for the update design of street public space from the perspective of security.
