| 摘要: |
| 互花米草（Spartina alterniflora）为美国大西洋沿岸的本地种，在环太平洋沿岸被认为是入侵物种。互花米草作为本地种，被誉为“生态系统工程师”；作为外来物种，其入侵特性亦引起相关领域的高度关注。为加深对互花米草相关研究的认知，探索未来研究重点方向，文章基于文献计量学方法，以Web of Science数据库中发表于1972—2020年的互花米草英文文献为基础数据，使用VOSviewer软件定量分析互花米草的研究进展及发展趋势。研究结果表明：1972—2020年互花米草领域的发文数量与被引频次均不断上升，2004年后呈快速发展态势；研究领域涉及的学科有生态学、环境科学以及海洋与淡水生物等；美洲、亚洲、欧洲与大洋洲等区域发表论文较多，其中美国在该领域的研究实力最强，中国其次；互花米草领域的研究热点集中于其对盐沼湿地生态系统的影响、生物地球化学循环过程以及生理生态和种间相互作用等，未来的研究趋势则集中于其对蓝碳的贡献以及对全球气候变化的响应过程与机制等。 |

| Abstract: |
| Spartina alterniflora is native to the Atlantic coast of the United States, which is recognized as an alien species along the Pacific coast. S. alterniflora has attracted much attention in related fields for many years. In order to deepen the understanding of S. alterniflora related research, and explore the future research priorities, the paper analyzed its research progress quantitatively and protracted visual knowledge graph by VOSviewer software with the key words of S. alterniflora during 1972-2020 from Web of Science database by bibliometric analysis method. The number of published papers and citations of S. alterniflora has been rising during 1972-2020, and shown a rapid development trend since 2004. The research areas covered ecology, environmental science, marine and freshwater biology. The publications were mainly contributed by countries in America, Asia, Europe and Oceania, and the United States ranked the 1st followed by China. The topics of S. alterniflora focus on its effects on salt marsh ecosystem, biogeochemical cycle, physiology and interspecific interaction. S. alterniflora′s contributions to blue carbon and responses to global climate change is the current hot topic in coastal salt marshes. |
