中文摘要：

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。

英文摘要：

This study focused on the evolution of emergy synthesis and its network characteristics. A visualized analysis of emergy papers from 1995 to 2015, obtained from the Web of Science database, were analyzed by applying bibliometric and network analysis methods. Result showed that= 1） From the whole development point of view,the main research fields focused on disciplines such as ecology and environmental sciences. These countries such as China, the US and Italy made more contributions to the development of emergy synthesis due to a large number of research papers published. 2）From the research hotspot point of view,in earlier research, it was mainly focused on the improvement and development of emergy synthesis;however,with the widely accepted,there has been more and more applications and improvement of emergy synthesis in recent years. In conclusion, the development trends of emergy synthesis were identified from perspective view of system, and also the research fronts and hot topics of this research field were revealed,above all,our study provided the references for the development of emergy synthesis in future.
