基于Citespace的气候变化对海洋生态影响研究状况分析

Citespace-based analysis of research state on climate change effects on marine ecology

为探明气候变化对海洋生态影响方面的研究,采用科学计量软件Citespace从Web Of Science核心数据库中选取2018~2022年间发表的关于气候变化对海洋生态影响的研究论文进行定量分析。从研究国家、机构、作者、期刊和关键词等方面展开可视化定量分析并进行结果总结。结果表明:2018~2022年,发文量最大的国家为美国;以WANG C为核心的团队发文量最多;从关键词分析上看,研究者们主要从海洋酸化、珊瑚礁、海平面上升、物种分布模型和北极熊等方面研究气候变化对海洋生态的影响;关键词的突现检测结果显示,继早年研究气候变化对海洋生态造成的危害后,海洋生态系统的恢复成为近年来的新热点和趋势。随着气候变化和人类活动的加剧,海洋生态受到严重破坏。研究成果可为海洋生态方面的研究者提供参考。

To explore the research state on climate change effects on marine ecology,a quantitative analysis of research articles on the climate change effects on marine ecology published between 2018 and 2022,which were downloaded from the Web Of Science core database,was conducted by using the Citespace software.The quantitative analysis was visualized and summarized in terms of research countries,institutions,authors,journals,and keywords.The analysis results showed that the country with the largest number of publications was the United States,and the team with WANG C had the most publications among all authors.From the keyword analysis,researchers were mainly found to study the impact of climate change on marine ecology in terms of ocean acidification,coral reef,sea level rise,species distribution models,and polar bears.The results of keyword emergence detection showed that,besides the previous research on the impact of climate change on the damage caused by climate change on marine ecology,the restoration of the marine ecosystem had become a new hot spot and trend in recent years.With the intensification of climate change and human activities,marine ecology had been seriously damaged.This study can provide a reference for researchers in marine ecology.
