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