基于层次分析法的台风灾害直接经济损失评估

Evaluation on Direct Economic Loss Caused by Typhoon Disaster Based on Analytic Hierarchy Process

提出了一种基于监测数据汇聚和数据建模分析对台风灾害在一定区域内造成的直接经济损失的评估方法。通过合理选取致灾因子,确定台风灾害风险危险性指数、台风孕灾环境敏感性指数、台风经济脆弱性指数等指数数值和评级,求出台风灾害经济脆弱性指标等级。然后,通过数据建模和计算分析,实现致灾因子危险性评估、承灾体暴露度分析和承灾体脆弱性分析,最后完成台风灾害直接经济损失评估。

It presents an evaluation method of direct economic loss caused by typhoon disaster in a certain area based on monitoring data aggregation and data modeling analysis.By reasonably selecting the disaster causing factors,the index values and ratings of typhoon disaster risk index,typhoon disaster pregnant environmental sensitivity index and typhoon economic vulnerability index are determined,and the economic vulnerability index grade of typhoon disaster is calculated.Then,through data modeling and calculation analysis,the risk assessment of disaster causing factors,the exposure analysis of disaster bearing body and the vulnerability analysis of disaster bearing body are realized,and finally the direct economic loss assessment of typhoon disaster is completed.
