The Research On Rish Assessment Method Of Shenzhen Based On The City Emergency Management

Today, with the accelerating urbanization process, the population has beengrowing very fast in the city, and villages and towns around the city are alsoincorporated into the development plan of the core city. However, on the premisethat the city management system haven't matured, the excessive concentration of thepopulation will result in the occurrence of disaster risk in urban areas, and causingmass casualties, economic losses and social negative impacts. China is in a period ofsocial transition, a variety of human and non-human disasters are common, and theyhave brought unfavorable influence to the people's production activity and life.Sometimes disasters can't be avoided, but in many cases, the occurrence and impactof disasters are predictable, controllable. As the core of disaster beforehand defense,disaster risk assessment has gradually become the focus of world attention.In this research, some analysis and confrontation of the evaluation methods ofthe comprehensive disaster risk have been done, and on the basis of the matureresearch in western countries, we use some effective factors related to the referenceadopted by thinking and knowledge of disaster risk assessment model. At last, wefinally proposed suitable disaster risk assessment model with considering the entiresituation of the local region, and aim to improve the disaster risk managementmethod by providing concrete method and means.This paper focus on finding out the core link in the city emergencymanagement for disaster risk assessment, and have designed a four-step possess:risk assessment preparation, risk identification, risk analysis, risk assessment. Theyare the core framework in the city emergency management; we also analyzed thekey role each step played in the city emergency management and the resultingeffects.The full studies have used the following methods: the data collection method,experience summary, case study, comprehensive analysis, literature research, andcomparative research and analysis methods. They all were used to study the cityemergency management framework, management mechanism and mode of operation,and derive disaster risk assessment model, so in final, we established an emergencysituation mechanism for China's local assessment, monitoring, early warning,emergency preparedness and disposal management methods and processes.With the risk assessment experience gain in the China-German project onemergency item carried out in Baoan District, Shenzhen, the use of multi-angle,multi-paradigm approach, discussed elements of the city emergency managementand the disaster risk assessment. At the last part of this research, we use two cases of Baoan District as a sample risk assessment model, summed up that the focus of thecurrent city emergency work needs much more attention, and provide effectivereference for China to carry out disaster risk assessment study.
