基于属性-集对耦合的山洪灾害风险后果评价
Risk Consequence Evaluation of Flash Flood Disaster Based on Attribute-Set Pair Coupling
摘要
Abstract
In response to the significant differences in the spatiotemporal distribution of flash flood disasters and the uncertainty of influencing factors in the evaluation process,which can easily cause distortion of evaluation index values and loss of risk index information,evaluation indices were divided into loss of life,economic loss,environ-mental impact,and social impact.Their grading standards were subdivided,and quantified.The variable weight theory was used to modify the combination of constant weight,and the attribute measurement comprehensive evalua-tion vector was used to transform and analyze the uncertainty information.Combined with the attribute set pair coef-ficient,the severity of disaster consequences was judged,and a risk consequence evaluation model based on attri-bute-set pair coupling was constructed.The model was applied to the evaluation of flash flood disasters in the 20 a,50 a and 100 a return rainstorm scenarios in Guxian County,Shanxi Province.The results showed that the model could effectively quantify the risk consequence grades under rainstorm scenarios with different return periods,which was basically consistent with the evaluation grades calculated by other models,demonstrating the good applicability of the proposed method.关键词
