摘要:

本文基于城市安全韧性三角形模型, 构建韧性城市视角下的风暴潮灾害综合风险评价框架, 采用2011—2020年福建省33个沿海县(区、市)数据, 通过城市适灾韧性评价指标体系, 科学评价福建沿海城市适灾韧性水平时空分异特征, 借助地理信息分析工具, 综合风暴潮灾害危险性、脆弱性和城市韧性的评价结果, 实现福建省域尺度风暴潮灾害综合风险区划。结果表明: (1)福建省2020年沿海城市适灾韧性水平从高到低依次为: 福州、厦门、漳州、泉州、宁德、莆田; (2)随着各沿海城市适灾韧性水平的稳步提升, 福建省风暴潮灾情等级指数呈下降趋势; (3)风暴潮综合风险I级区主要分布在莆田的兴化湾、湄洲湾沿岸; (4)在灾害防御建议方面, 应重点关注河口、喇叭型湾口等地区, 应重点防范北部路径和中部路径的台风风暴潮, 应因地制宜制定海洋防灾减灾对策和韧性城市建设规划。

Abstract:

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.
