Bibliometric and visualization tools are effective for uncovering information contained in vast amounts of literature data. We retrieved publications from the Web of Science (2008–2020) and used the Statistical Analysis Toolkit for Informetrics (SATI) and CiteSpace to conduct a bibliometric analysis of emergy studies, review the focus of the studies, summarize current research, and identify academic trends. The SATI-based charts provided an overall description of yearly published articles, literature sources, high-frequency keywords, authors, institutions, and highly cited papers. CiteSpace was applied to determine the frontiers and hotspots of emergy theory. A dual-map analysis was used to reveal the connection between multiple disciplines. Keyword clustering analysis was performed to evaluate research hotspots. Moreover, burst analysis and timeline maps presented a holistic picture of cutting-edge issues and the evolutionary trajectory of emergy studies in recent years. An alluvial flow map analysis of the landmark literature depicted the transmission of knowledge in the emergy field. In addition, this article also evaluated the current status of collaborative research in emergy-related fields. The results can provide a reference for researchers to explore hot issues or target a specific field of study.

文献计量和可视化工具AR Ë有效地揭示包含在大量文献数据中的信息。我们从 Web of Science (2008–2020) 检索出版物，并使用信息计量学统计分析工具包 (SATI) 和 CiteSpace 对能值研究进行文献计量分析，回顾研究重点，总结当前研究，并确定学术趋势. 基于 SATI 的图表提供了对年度发表文章、文献来源、高频关键词、作者、机构和高被引论文的总体描述。应用 CiteSpace 确定能值理论的前沿和热点。双图分析被用来揭示多个学科之间的联系。进行关键词聚类分析以评估研究热点。而且，爆发分析和时间线图展示了近年来前沿问题和能值研究的演变轨迹的整体图景。具有里程碑意义的文献的冲积流图分析描述了能值领域中的知识传播。此外，本文还对能值相关领域的合作研究现状进行了评估。研究结果可为研究人员探索热点问题或针对特定研究领域提供参考。
