Research On Emergency Management Evaluation Of Earthquake Safety Community Based On Matter Element Extension Method

Earthquake as sudden and unpredictability of major natural disasters throughout the world,of the most deadly of personal casualty and property loss caused by the earthquake,China is located in the Asia and Europe and the Pacific plate boundary,with the development of national economy and the speeding up of urbanization,the traditional single construction engineering seismic disaster mitigation measures has been far from effective prevention and control potential earthquake disaster risk’s impact on national development.Taking the earthquake safe community as the earthquake disaster reduction unit,and comprehensively considering the impact of engineering structure,management and operation on the emergency response of the community,the emergency management evaluation system of the earthquake safe community is built scientifically to achieve the systematic and scientific disaster prevention goal.Based on the exploration of the emergency management problems of earthquake safe communities,this paper analyzes the concept and development trend of community disaster prevention construction at home and abroad,summarizes relevant theories of earthquake safe community construction and safety emergency response in China,and clarifies the important role of emergency management of earthquake safe communities in disaster prevention management system.According to the characteristics of earthquake safe communities and the occurrence mechanism of emergencies,the indexes are extracted according to the influencing factors involved in earthquake safe communities’ emergency preparedness before,emergency response during and emergency recovery after disasters.In addition,the evaluation index system of emergency management in earthquake safe communities is established hierarchically,and the target layer,criterion layer and index layer of the evaluation system are set up.The combined weight method and matter-element extension mathematics theory are innovatively applied to the construction of emergency management evaluation system of earthquake safe communities.Through the existing relevant research,expert opinions and practical investigation,the index evaluation standard is established,the index weight is determined by the combination optimization method,the evaluation process of emergency management is designed,and the evaluation result of disaster emergency management is obtained by the comprehensive evaluation model.Finally,by selecting the case of the demonstration community of earthquake safety in China,the data collection and analysis of the post-earthquake community emergency indicators are carried out,and the current situation of community emergency management is evaluated and analyzed by using the established evaluation system to obtain the evaluation level of the earthquake safety community.The applicability and correctness of the evaluation system are verified by the degree of the evaluation results in accordance with the actual situation of the community,which provides valuable reference for the construction and management of safe and intelligent communities.
