The Research Of Urban Safety Evaluation System Construction

With the urbanization of our society speed up, Cities do not only face the opportunities for development, But also there are increasingly complex social structure and profound changes in the external environment. Currently, We are faced with city security threats,and it becomes complex and acute day after day. Overall city security issues has seriously affected the healthy development of cities, modern city life changes because of safety.The research is based on urban security concepts and city safety evaluation category explore urban safety evaluation system of the relationship between the various factors,aimed at the theoretical analysis and practical inspection level safety evaluation of city of theory and study,research on how to construct the city safety evaluation system. Content mainly focus on urban security concepts, urban safety evaluation system construction, urban safety evaluation index of quantitative algorithm, city of safety evaluation system simulating experiment, city of safety evaluation for practical inspection and so on. The main research contents:First,According to the city ,urban disaster,urban sociology relevant knowledge, Comprehensive analysis of the concept of urban security should include the natural disasters, social emergencies and other has valid resist ability , And in environmental, social and personal health dynamic equilibrium and maintain a coordinated development, Can provide good order, city residents living space and personal comfort three meanings.Second,Using safety related theory establish a city security evaluation system model, This model including urban disasters, social security, city fire, living guarantee, budgetary revenues and expenditures, ecological environment, emergency rescue and medical and health, safety management nine factors. Elements of the selected combining safety evaluation system is the basic theory, and considered of contemporary urban safety concept.Third, Use statistical methods to urban safety evaluation index quantitative algorithms To identify various elements and index factors weights.Forth,according to urban safety evaluation system ,Just nanjing, hangzhou, ningbo city safety evaluation adaptability inspection.
