Research On Earthquake Disaster Prevention And Mitigation Management In City

As a country with frequent earthquake, our country suffered a serious of earthquake disasters from ancient times to the present, which caused a great loss to people’s lives and property. In the process, we have been exploring to reduce the loss caused by disasters. With the acceleration of urbanization progress nowadays, in the event of earthquake disasters, the loss is estimated. So the study of the ability for city earthquake disaster reduction management is not only the necessary premise of our current protection against earthquake disasters, but also an important guarantee for the work of earthquake disaster relief.Firstly, the author introduced the earthquake disaster influence on different aspects of the cities in our country. In order to make it more complete of the earthquake disaster prevention and mitigation system, he found out the scholars study omissions, and put forward in this paper through literature reviewing.Through analyzing the principle and characteristics of earthquake disasters, he explores the basic theory of protecting against and mitigating earthquake disasters. in order to make us more fully in the running of the city of earthquake disasters, through literature at home and abroad city earthquake disaster reduction management ability contrast, combined with the domestic two typical seismic hazard analysis, finally through the selection of index, constructed the mitigation of earthquake disasters management capability evaluation index system. Including local government management system, professional rescue teams mitigation of earthquake disasters mitigation of earthquake disasters management system, social basic construction unit of earthquake disasters for reducing seismic disaster management system management system, professional volunteers, community management system level indexes such as mitigation of earthquake disasters and the corresponding 17 secondary indexes.Second expert scoring method is used to draw two judgment matrix, calculated using analytic hierarchy process (AHP) level weights of indicators and secondary indicators. Calculate the key indicators and the corresponding specific weights are children, and through the consistency check, eventually to rank weights and determine its importance.Through the study of the empirical analysis of xi’an finally, adopt the method of questionnaire on xi’an citizens for data statistics, and the fuzzy evaluation test analysis and calculation. Results with the analytic hierarchy process (AHP) to draw weight comprehensive comparison. According to the important degree of urban earthquake disaster reduction management order, it can be seen that xi’an earthquake disaster reduction management system of local government and community management system in two aspects of mitigation of earthquake disasters of weight is higher, but is generally the fuzzy comprehensive evaluation, so let’s focus on strengthening the construction of this system. And the other indicators to constantly improve, and then the corresponding secondary index, the contrast results still levels not neat, it represents the xi’an there are varying degrees of protecting against and mitigating earthquake disasters management loopholes, the relevant departments can be targeted for improvement, at the same time this research method can also be used to evaluate other city earthquake disaster reduction management ability and so on.
