基于Citespace国内近二十年三语习得研究述评
Based on Citespace: Research on Third Language Acquisition in the Past Two Decades

文章聚焦国内2000~2021二十一年间中国知网关于三语习得的研究，运用Citespace可视化分析软件，对二十一年间发表的相关论文分析，探究国内研究热点并预测未来发展趋势。研究结果显示：国内三语习得研究正处于平稳上升期，综述性文章居多，实证性研究还有较大发展空间；研究热点主要集中于语言迁移和三语教学；但是国内三语习得领域尚未形成大规模研究，学科交叉性不强以及研究内容所涉及面偏窄。研究结果表明，未来三语习得相关研究应拓展研究领域，在三语教学以及实证研究方面进行深度挖掘和探讨，并探索以汉语作为三语的国际范围研究。
This paper focuses on the domestic studies on third language acquisition on CNKI from 2000 to 2021, and uses Citespace, a visual analysis software, to conduct research on relevant papers published in the past 21 years, detecting domestic research hotspots and predicting future development frontiers. The findings are as follows: The research on third language acquisition in China is on a steady rise with the majority of review articles, and there is a large space for empirical research. And the research hotpots are language transfer and third language teaching. However, there are still some problems in the research of third language acquisition in China, such as the lack of scale for research, lack of cross-discipline study and narrow scope of research content. Research results indicate that future research on third language acquisition may be expanded to explore more, discussing third language teaching and empirical research deeply, and seek for the international scope of research on Chinese as a third language.
