Urban public safety evaluation method based on risk and capability

Abstract

The invention discloses an urban public safety evaluation method based on risk and capability, which divides urban public safety evaluation into four stages of existing risk evaluation, residual risk evaluation, emergency capability evaluation and urban public safety evaluation. The method considers the inhibition effect of the capability on the risk and the comprehensive influence effect of the capability and the risk on the urban public safety, carries out the existing risk evaluation, screens major risk event scenes, evaluates the residual risk in combination with the prevention and control capability, analyzes the scene task, evaluates the emergency capability, and carries out the safety evaluation based on the staggered influence of the risk and the capability. And comprehensively evaluating the urban public safety level. According to the embodiment of the invention, different management perspectives and different evaluation perspectives of the urban public safety are effectively fused, the inhibition effect of the capability on the risk and the comprehensive influence effect of the risk and the capability on the urban public safety are reflected, and systematic analysis and comprehensive evaluation of the urban public safety can be realized.

Description

technical field [0001] The invention relates to the field of urban public security assessment, in particular to a method for evaluating urban public security based on risk and capability. Background technique [0002] As urbanization continues and more people will live in urban areas, managing urban areas has become one of the most important development challenges of the 21st century. As the scope of interaction between human society and the natural world gradually expands and the degree of interaction deepens, the barriers between traditional natural disasters, technological disasters, social security, and public health in the field of public security are being broken down. The concept of "big security" is gradually established. In this context, it is particularly important to comprehensively evaluate the degree of urban public security to improve the security resilience of the city and promote the sustainable development of the city. [0003] The field of urban public se...

Problems solved by technology

However, at present, there are few research results that can provide a comprehensive and systematic analysis idea of ​​"all disasters, the whole process, and all directions"; the comprehensive evaluation method based on the index system is usually based on the analytic hierarchy process, fuzzy comprehensive evaluation method, and weighted calculation method , although it is simple and easy to implement, it cannot deeply consider the evolution mechanism of disaster risk, which may easily lead to the neglect of major disaster risks; existing studies have considered disaster link effects and established mathematical models to evaluate urban disaster risks, but the types of disasters involved in cities There are many, large number of hazard sources, and it cannot be well promoted and used in practice due to the difficulty of data collection

[0004] Chinese invention patent "A comprehensive risk assessment method for social public security in urban communities (CN111798112A)", discretize the evaluation area space and establish an information set, and evaluate social security incidents and times from three dimensions of possibility, severity, and coupling However, the plan lacks the consideration and analysis of various disasters such as urban natural disasters and accident disasters, and also lacks the reflection of the weakening and restraining effect of urban emergency response capabilities and prevention and control capabilities on urban risks, making it difficult to comprehensively evaluate urban public safety. degree
