Safe city evaluation system and method

Abstract

The invention provides a safe city evaluation system and method, and belongs to the field of safe cities and city safety level evaluation. The system comprises an index system establishment unit, an urban operation system data acquisition unit, a risk prevention capability data acquisition unit, a weight acquisition unit and a data processing unit. The index system establishing unit establishes an index system of a city to be evaluated; the city operation system data acquisition unit is used for acquiring data related to a city operation system of a city to be evaluated; the risk prevention capability data acquisition unit is used for acquiring data related to the risk prevention capability of a city to be evaluated; the weight acquisition unit is used for acquiring a weight; and the data processing unit is used for obtaining the comprehensive score of the city to be evaluated and obtaining the security level of the city to be evaluated according to the comprehensive score. According to the method, safe city evaluation is carried out, the safety level corresponding to the to-be-evaluated city can be obtained finally, and scientific decision reference is provided for safe city construction.

Description

technical field [0001] The invention belongs to the field of safe city and city safety level evaluation, and in particular relates to a safe city evaluation system and method. Background technique [0002] The continuation of human civilization is inseparable from the development and construction of cities, and safety is the core point of urban construction. In recent years, with the acceleration of urbanization in our country, various emergencies have occurred continuously, which not only caused huge economic losses, but also posed a huge threat to the lives of residents. Therefore, it is particularly important to make a reasonable evaluation of urban security to better provide scientific decision-making support for safe city construction and urban security. [0003] The current safe city evaluation methods mostly select indicators from the perspective of the three major urban operating systems: economic system, environmental system, and social system, or the four types of...

[0003] The current safe city evaluation methods mostly select indicators from the perspective of the three major urban operating systems: economic system, environmental system, and social system, or the four types of urban emergencies such as natural disasters, accident disasters, public health events, and social security events. evaluation, seldom considers from the perspective of "risk" and also seldom evaluates the city's disaster resistance ability. Even the few evaluation methods that consider the disaster resistance ability mostly select quantitative indicators similar to the urban operating system or urban emergencies. However, although these indicators can indirectly reflect the city's disaster resilience, they cannot systematically and targetedly provide decision-making reference for improving the city's disaster resilience. In addition, "risk" as the cause of various urban emergencies is lacking. Consideration will also affect the reliability of safe city evaluation
