Abstract

Abstract:

To improve the city's resilience in responding to public safety risks, an integrated theoretical model of "spatial resilience" for urban public safety was proposed, and an urban public safety resilience evaluation index system was developed from the perspective of residents' perceptions. The entropy weight method was used to evaluate the public safety resilience level for Nanjing comprehensively. The results indicated that the overall score of Nanjing's public safety resilience was 6.851 5, and there was a structural imbalance in the resilience construction for the ternary space. Furthermore, social space safety resilience was the highest, followed by information space safety resilience, and physical space safety resilience was the lowest. The unbalanced development of urban public safety space resilience can be attributed to several factors including the lack of overall public safety resilience governance, insufficient investment in infrastructure and equipment maintenance, an imperfect social environmental risk monitoring system, and weak information security awareness and literacy among residents. Specific measures can be taken from the aspects of humanistic concepts, clear strategies, systematic thinking, and diversified cooperation.

Key words: urban public safety, risk perception, ternary space, spatial toughness integration, resilience assessment, index system
