【 摘 要 】

To achieve scientific, effective and accurate prevention and control of major emergency, this paper summarizes and summarizes the research status of risk assessment at home and abroad. The paper summarizes and analyzes the current status and existing deficiencies of existing risk assessment studies from the types of events, time characteristics and event chains. The results of the thesis suggest that the primary problem of the current research is that the risk assessment is mostly based on the subjectively strong indicator system method, and the evaluation results cannot directly reflect the physical relationship between the risk level and the impact of the event. The consideration of risk dynamic characteristics is the focus and difficulty of the future risk assessment and evaluation process. Based on the theory of complex systems, the disaster chain has become the key to scientifically characterizing the level of risk.
