为揭示研究主题的发展及研究网络的演化,运用文献计量学以及网络分析方法对1995—2015年Web of Science核心数据库中能值理论的相关文献进行可视化统计分析。结果表明:1)从整体发展上看,研究领域主要集中在生态环境等相关学科。研究主要贡献国家为中国、美国和意大利。2)从研究热点看,早期的研究主要集中在对能值理论的自身完善和发展。近几年随着能值理论被广泛接受,能值理论得到进一步的完善和应用。通过以上研究,我们系统的识别了能值理论的发展趋势,揭示了该领域研究前沿、热点问题,对未来能值理论的进一步应用发展提供了参考。
In order to reveal the development of the research topic and the evolution of the research network, the literature of emergy theory in the Web of Science core database from 1995 to 2015 was visualized and statistically analyzed with bibliometrics and network analysis. The results show that: 1) From the overall development point of view, the research areas mainly focus on ecological environment and other related disciplines. The main contributors to the study are China, the United States and Italy. 2) From the research hotspot, the earlier research mainly focused on the perfection and development of emergy theory itself. In recent years, as emergy theory is widely accepted, emergy theory has been further improved and applied. Through the above studies, we systematically identify the development trend of emergy theory, reveal the research frontiers and hot issues in this field, and provide references for the further application and development of future emergy theory.
