Research On The Monitoring System And Tracking Assessment Used In The Major Emergency Risk

In the "golden period" of economic and social development, our country sufferedall kinds of major emergencies. These incidents not only have bought huge losses topeople’s lives and property, but also affected the sustainable economic and socialdevelopment. That effectively preventing to major emergency, and reducing the riskof possible loss in maximum, even putting the risk to the bud, is placing in front of thegovernment. The scientific prevention of major emergencies risk is based on systemmonitoring and tracking assessment. By monitoring and tracking system for the riskassessment of major emergencies, people can acquire, and analysis of risk factors ofmajor emergencies data information, to find the inherent law of the evolution of risk,and grasp the trend of risk, loss and its influence on the risk of possible scope, whichhave solid foundation for prevention to major emergencies. In major emergency risk,therefore, the system monitoring and tracking evaluation research has a strongpractical significance.The paper researches on the system monitoring and tracking assessment of majoremergencies. Firstly, it expounds the connotation of risk of significant events andtypes, and discussed the risk identification of major emergencies. Secondly, this paperdiscusses the system for monitoring the risk of major emergencies. Theimplementation of risk system of major emergencies monitoring must followrepresentative, accuracy, timeliness and other basic principles, differentiate the basicelements of the disaster-causing factors, disaster object, disaster environment, graspthe key means of video monitoring, sensor monitoring, spectrum monitoring. Thirdly,it implies the tracking assessment of the risk of major emergencies. The evaluation ofemergency must be based on the similarity principle, correlation and statistical system,the rational risk assessment index system, GIS, simulation, risk probability model,followed by hazard identification, hazard characterization, exposure assessment, riskdescription of the risk assessment process, and risk assessment results of grading.Finally, it discusses the risk of major emergencies prevention strategy, mainly fromstrengthening the consciousness of risk prevention, clear the governmentresponsibility, strengthen risk monitoring system and normalized step by step, perfectthe risk tracking assessment, gradually standardized, reasonable prevention measures,and gradually systematized and so on four aspects discussed the risk preventionstrategies of major emergency.
