摘要:珊瑚礁生态系统在全球海洋生态中扮演着重要角色，它为热带海洋动物提供栖息地，为人类提供食物药物资源，是全球生产力最高的生态系统之一。为了解当前国内外珊瑚相关研究的现状与热点，利用文献计量的方法统计分析了珊瑚的相关研究。文章分别以WEB OF SCIENCE数据库和中国期刊全文数据库（CNKI）中期刊论文为国际和国内的数据源，从文献计量的角度出发，利用Excel按年份统计论文的发文数量，通过Bibexcel得出高频词共词矩阵，并用Ucinet和Netdraw得出共词网络可视化图谱。利用SPSS进行聚类分析，分别将国内外相关研究分为四大类，分析珊瑚相关研究趋势与热点。研究表明：①国际与国内的珊瑚研究除个别年份有所回落，均基本成逐年上升趋势，大致于20世纪90年代开始进入成熟阶段，但国内的研究略迟于国际；②国际上对珊瑚的研究更倾向于探究珊瑚礁退化的原因，而国内则以提高珊瑚礁的造礁能力为研究热点；③通过共词分析得出，国际研究高频词中的coral reefs，corals，climate change，sedimentation，一定程度上也可视为研究热点；④通过聚类分析，国内外的珊瑚研究有一定的相似性，主要集中在珊瑚礁生态系统、影响珊瑚的环境因子、气候因子等几个方面，但国内外研究又各有侧重。总结得出，有关珊瑚、珊瑚礁研究在国内外均以珊瑚礁为重点，近年来和未来珊瑚礁研究注重于珊瑚礁修复或帮助珊瑚礁生态系统自行恢复。



Abstract:Coral reef ecosystems play an important role in the global marine ecosystem by providing habitats for tropical marine animals, providing food and drug resources to mankind, and protecting coasts from the beating of waves. The coral reef ecosystem is one of the most productive ecosystems in the world. In order to understand the status quo and hotspots of coral-related research in our country and the whole world, this study used the method of bibliometrics to statistically analyze the studies that are related to coral reefs. Bibliometrics is a method of mathematical statistics that is used to analyze and excavate information from many papers. In this study, the WEB OF SCIENCE database and the Chinese national infrastructure (CNKI) were the international and domestic data sources respectively. For the bibliometrics, this study used Excel to calculate the number of publications according to the year, Bibexcel to create a high-frequency co-word matrix, and Ucinet and Netdraw to draw a co-word network visualization map. Then, SPSS was used to analyze coral research trends and hotspots by dividing related international and domestic studies into four clusters each. This research showed: ① According to the number of papers, the progress of international research had two periods, and the progress of domestic research can be separated into four parts: tentative exploration, embryonic development, fluctuating growth, and steady increase. The number of international and domestic studies on corals both had a roughly increasing tendency, although some years showed a decline. International and domestic studies came into maturity in the 1990s, but domestic studies were slightly later than international. ② The highest-frequency words in international studies were coral, coral reefs, coral bleaching, and climate change, while in domestic studies they were coral reef, Scleractinian corals, Scleractinia, and Weizhou Island. International coral studies were more inclined to explore the causes of coral reef degradation, while domestic research was focused on improving the reef-building ability of coral reefs. ③ According to the co-word analysis, the high-frequency key words from international studies coral reefs, corals, climate change, and sedimentation can be viewed as study hotspots to some extent. ④ According to cluster analysis, there was similarity between international and domestic studies. They both mainly focused on the aspects of the coral reef ecosystem and environmental and climatic factors that are affecting corals, but both international and domestic studies have their own inclinations. In a summary, because the current state of coral reef degeneration is serious, international and domestic studies have both focused on coral reefs. In recent years and in the future, studies about corals and coral reefs may pay more attention to the topic of restoring coral reefs or helping coral reef ecosystems recover on their own.
