摘要
海岸带地质灾害严重影响了沿海地区的发展。为分析国内外海岸带地质灾害风险评估研究现状、发展态势及为我国在这一领域内的科研及防灾减灾等工作开展提供借鉴,本文以Web of Science和中国知网数据库中的相关文献为基础,运用CiteSpace软件对该领域的国内外发文量、发文国家和关键词进行知识图谱分析,探讨其研究热点及演变趋势。研究结果表明:(1)国内外研究均呈增长趋势,我国是该领域主要发文国家之一;(2)印度等国家发文量较多,且国家间存在合作研究关系,但不同国家的研究侧重点不同;(3)国内外关于海岸带地质灾害风险评估领域的研究热点包括海水入侵风险、海岸侵蚀风险和考虑其它地质灾害或综合灾害影响的海岸脆弱性及灾害风险评价;国际上,以气候变化和人类活动影响下的海岸带灾害管理研究亦为该领域研究热点之一;(4)随着时间的推移,国内外在该领域针对灾害风险的研究更加细化、评估手段更加多样、评估对象趋向完善。即海岸带地质灾害风险评估研究仍处于发展阶段,并取得了阶段性成果。但其理论和评价体系仍待完善;同时,我国在该领域的研究对象应不断完善,研究手段应更加系统、全面。
Coastal geological disasters have seriously affected the development of coastal areas.In order to analyze the research status and development trend of coastal geological disasters risk assessment at home and abroad,and to provide reference for the development of scientific research and disaster prevention and mitigation in China,this paper uses CiteSpace software to analyze the knowledge map of domestic and foreign publications,publishing countries and keywords in this field.The research hotspots and evolution trends are discussed based on the relevant literature in Web of Science and CNKI database.The study concluded that:(1)Research both at home and abroad show an increasing trend,and China is one of the main publishing countries;(2)Countries such as India publish a large number of papers and there are cooperative research relationships between countries,but different countries have different research focuses;(3)Research hotspots in the field of coastal geological disasters risk assessment at home and abroad include research on seawater intrusion risk,research on coastal erosion risk,coastal vulnerability and disasters risk assessment considering the impact of other geological disasters or comprehensive disasters.Research on coastal zone disasters management under the influence of climate change and human activities is also one of the international research hotspots in this field;(4)Over time,the research on disaster risk in this field at home and abroad has become more detailed,the evaluation methods have become more diverse,and the evaluation objects have become more and more perfect.In a word,the research on the coastal geological disasters risk assessment is still in the development stage,and staged results have been achieved.However,its theory and evaluation system still need to be improved.At the same time,the research objects in this field in our country should be continuously improved,and the research methods should be more systematic and comprehensive.
