Study on comprehensive risk assessment of storm surges for Fujian Province from the perspective of resilience
Based on the triangle model of urban safety resilience,this paper constructs a comprehensive risk assessment framework for storm surge disasters from the perspective of resilient cities.By using the data of 33 coastal districts in Fujian Province from 2011 to 2020,and through the urban resilience evaluation index system,this paper scientifically evaluates the spatial-temporal differentiation characteristics of urban resilience level in Fujian Province.With the help of geographic information analysis tools to evaluate hazard,vulnerability of storm surge disasters and urban resilience,the comprehensive risk assessment of storm surge disasters at the regional scale for Fujian Province is realized.The results show that:(1)the resilience level of coastal cities in Fujian Province in 2020 is at a descending order:Fuzhou,Xiamen,Zhangzhou,Quanzhou,Ningde,Putian;(2)with the improvement of urban resilience level,the storm surge disaster index of Fujian Province is showing a downward trend;(3)the comprehensive storm surge risk level I zone is mainly distributed along the Xinghua Bay and Meizhou Bay in Putian City;(4)we should pay attention to estuaries,trumpet shaped bays and other areas,focus on preventing typhoon storm surges along the northern and central routes,and formulate marine disaster prevention countermeasures and resilient city construction plans according to local conditions.
