摘要
科学地进行海洋承灾体灾害脆弱性评价,是完善海洋灾害监测、预警、防控体系的基础,是海洋灾害风险管理的重要组成部分。本文以海洋动力灾害多发的海口市为例,在系统开展承灾体调查分析的基础上,从自然和社会属性两个方面对该市进行了脆弱性分析和评价。利用GIS技术,对研究结果进行了标准化制图。结果表明,海拔较低的港湾地区、人口密集区更易受到海洋动力灾害的影响。海口市极高脆弱性区域共439 km^(2),主要集中在人口和重要承灾体较密集的市中心秀英区、龙华区、美兰区北部沿海区域和西秀镇西部等区域。本文关于海洋动力灾害承灾体脆弱性的评价结果属于海口市专题海洋灾害风险调查和评价结果,可为海口市规划布局、海洋动力灾害风险防范提供重要参考。
Scientific vulnerability assessment of marine disasters is the basis of improving marine disaster monitoring,early warning,prevention and control system,and is an important part of marine disaster risk management.In this paper,Haikou city,which is prone to marine dynamic disasters,is taken as the research object.Based on the systematic investigation and analysis of disaster-affected bodies,the vulnerability of Haikou city is analyzed and evaluated from two aspects of natural and social attributes.Using GIS technology,the research results were standardized mapped.The results show that the coastal areas and densely populated areas with low altitudes are more susceptible to marine dynamic disasters.The extremely high vulnerability area of Haikou city is 439 km^(2),which is mainly concentrated in the areas of Xiuying district,Longhua district,the northern coastal area of Meilan district and the western area of Xixiu town.The vulnerability assessment results of this paper are the results of the first thematic Marine disaster risk survey and assessment conducted in Haikou city,which can directly serve the planning layout of Haikou city and the prevention of Marine power disaster risk.
