基于透镜效应的灾害风险感知理论框架研究
Research on Disaster Risk Perception Framework Based on Lens Effect
摘要
Abstract
Risk perception research has always been one of the hotspots of disaster research.However,its theoretical research has been not updated since the social amplification of risk framework was proposed,and it is urgent to introduce new theories to comprehensively interpret the process of risk perception.Using the lens imaging law in physics for reference,we creatively put forward the lens effect theory of risk perception.Disaster risk per-ception is the process that disaster scenarios information is received,processed and communication by risk stage to form risk images.In the formation of risk perception,disaster scenario and distance decay are two key factors that affect the size of risk image.The more serious the consequences of the disaster scenario,the greater the risk is per-ceived by the risk stage.Under the same disaster scenario,the distance between the disaster scenario and the risk stage changes,risk image showing real and virtual images respectively,and the closer the distance,the greater the risk image.The risk perception of the victims and the onlookers is different,but they all follow the law of distance decay,and the result of risk perception is evaluated by the size of risk image.The research on disaster risk percep-tion based on lens effect is the product of interdisciplinary integration,and it is also a theoretical contribution to the research on risk perception.关键词
