Study on the Evolution Mechanism of Urban Flood Disaster Social Risk Based on the Model of Four Dimensions of Social Amplification of Risk

摘要

Aiming at the problem that social stability and order is often seriously threatened by urban flood disasters, a four dimensions model of social amplification of urban flood disaster social risk amplification in Chinese transforming society is proposed on the basis of the theory of social amplification of risk. And then we analyzed the amplification mechanism of urban flood disaster risk. Besides, we studied the evolution mechanism of urban flood disaster risk evolving from individual risk to group events and then to social risk. Furthermore, we applied the amplification and evolution mechanism to the case study of Zhejiang Yuyao flood social risk. Finally, some advices are put forward to respond to urban flood disaster risk.
