基于多维空间耦合模型的综合灾害风险评价
Research on the Comprehensive Disaster Risk Assessment Based on Multidimensional Spatial Coupling Model
摘要
Abstract
With the acceleration of urbanization and the expansion of urban scale,it has changed greatly of the urban built environment has changed greatly,however the comprehensive disaster response capacity is insuffi-cient.In order to improve the comprehensive disaster response capacity,starting from the source root foundation and formation mechanism of disaster elements,the disaster pregnant environment,disaster bearing body and disas-ter causing factors are considered together,and the disaster risk assessment is conducted.Therefore,a multi-di-mensional spatial coupling model is constructed for the vulnerability of the disaster environment,the exposure of the disaster bearing body,and the risk of the disaster causing factors.A disaster risk assessment system is established,and a new method for disaster risk calculation combining the weighted comprehensive evaluation method is pro-posed.Taking the central urban area of Nanyang as an example,the study found that the overall comprehensive disaster risk in the central urban area of Nanyang continued to increase,but the growth rate gradually slowed down,and there are significant differences in disaster risks in different regions,The factors that cause disasters,the affect-ed entities,and the changes in the disaster environment during different periods have a significant impact on disas-ter risk,and the level of disaster risk are relatively high.关键词
