A case to identify the factors causing a disaster with risk reception

摘要

There are many factors affecting the disaster situation, and weights of various factors are different. Theoretical analysis results are only applicable to disasters and regions that meet theoretical assumptions. Based on the knowledge of some people about local earthquake disasters and flood disasters in Santai County, this paper proposes a method to identify the factors affecting disasters by risk perception. In the case, risk perception is reflected in the score of affecting factors' importance. The study found that the background of the respondents is closely related to their risk perception results. The factors affecting the disaster can be summarized as risk source factors, emergency ability factors and vulnerability factors. This study can provide a reference for the weights calculation in relative exposure.
