摘要:牡蛎礁作为重要的海岸带生态系统，具备水质净化、提供栖息地等多种生态系统服务功能。为了解国内外牡蛎礁研究的现状与热点，分别以Web of Science 核心合集数据库和中国期刊全文数据库为数据源，通过国内外发文趋势分析、高频关键词分析、关键词共现和聚类分析及主题时间演变分析等，分析牡蛎礁研究热点与趋势。研究结果表明：（1）国际与国内牡蛎礁研究发文量总体呈现上升趋势，但国内研究增长速率低于国际研究；（2）牡蛎礁生态恢复研究是国内外研究的共同关注点，但国内相关研究起步较晚；（3）以外，国际上对牡蛎礁的研究更加关注生态系统服务功能、气候变化等，而国内主要倾向于从地质学角度进行研究；（4）近年来，气候变化成为国际牡蛎礁研究新的热点，但国内对此关注较少。本研究将为了解当前国内外牡蛎礁研究现状及发展态势提供借鉴，并为我国牡蛎礁保护与修复方面的政策制定、科学研究等工作的开展提供情报参考。



Abstract:As an important coastal ecosystem, oyster reef provides many ecosystem service functions, such as water purification and habitat provision. To understand the present stitutation and hotspots of oyster reef research at home and abroad, Web of Science Core Collection and China National Knowledge Infrastructure database were selected as data sources in this study. The research hotspots and trends of oyster reef studies were identified from the perspectives of the trend analysis of domestic and international publications, high-frequency keyword analysis, keyword co-occurrence analysis, cluster analysis, and time evolution of theme. Results showed that: (1) the oyster reef research publications at home and abroad showed an overall upward trend, but the growth rate of domestic research was lower than that of international research; (2) The oyster reef ecological restoration study was a common focus of publications at home and aboard, but studies were conducted relatively late at home; (3) In addition, international researches of oyster reef paid more attention to ecosystem services, climate change, etc., while researches at home mainly focused on studies from the perspective of geology; (4) In recent years, climate change has become a new hotspot of international oyster reef research, but little attention was paid in China. This research will provide reference for understanding the current research status and development trend of oyster reef studies. This results will also offer information for making policies and conducting researches of the protection and restoration of oyster reefs in our country.
