消息、动态与进展

在《地震科学进展》创刊50周年之际，采用CiteSpace科学文献计量方法，对1979—2020年《国际地震动态》正刊所出版的7151篇文献进行作者合作网络分析和关键词共现分析，以期系统性探索过去不同时期《国际地震动态》出版文献的主题脉络、知识演进、历史热点和作者群发展。《国际地震动态》历年载文所体现的主题脉络的持续变化、知识演进的不断前推、历史热点的交换更替，充分体现出地震学的过去、现在与未来。在介绍科学交流和期刊出版模式演进的基础上，针对地震期刊 “多、散、弱” 的现状，提出整合地震局的科学资源，推进增强型期刊出版，吸引高水平文章在地震期刊首发的解困建议。 

News,recent developments and progressWritten on the 50th anniversary of Progress in Earthquake Sciences

On the 50th anniversary of Progress in Earthquake Sciences, the scientific bibliometrics methods supplied by CiteSpace are used to conduct author collaboration network analysis and keyword co-occurrence analysis of the 7151 papers published in Recent Developments in World Seismology from 1979 to 2020. The work aims to systematically explore the thematic context, knowledge evolution, historical hot spots and author group development of the publications of Recent Developments in World Seismology in the different periods. The continuous changes in the theme, advancement of knowledge evolution, and the exchange of historical hot spots showed by papers in Recent Developments in World Seismology fully reflect the past, present and future of seismology. Based on the introduction of scientific communication and the journal publishing model evolution, suggestions such as integrating the scientific resources of the China Earthquake Administration, promoting the intensive publishing, and attracting high-level papers to be initially published in seismic journals are put forward to solve the “multiple, scattered, and weak” problem of seismic journals.
