Abstract

Urban public emergencies now break out frequently, causing heavy losses and threatening urban sustainability at the same time. To help better curb public emergencies, minimize their damage to cities, and maintain the sustainable operation of the city, this paper takes the urban public emergency as the research object, discussing the formation mechanism of urban public emergencies and putting forward feasible countermeasures. First, we propose the concept of risk propagation chain and construct an urban socio-technical system risk propagation chain model by introducing the Tropos Goal-Risk framework. The risk propagation chain formation mechanism and the emergency formation mechanism are researched by using this model to analyze the specific conditions and paths of risk propagation. Then the targeted countermeasures are put forward to prevent and manage emergencies, advancing the goal of sustainable development. Finally, a case is used to verify the theory and model. This study not only provides a theoretical framework for the formation of urban public emergencies but also provides a practical method for modeling public emergencies and dealing with urban sustainability problems.
