近五年地质学领域研究热点的数据可视化分析

Data visualization analysis of research hotspots in geology in recent five years

本文选取2016年1月—2021年7月在地质学领域权威期刊《地质学报》《岩石学报》《地学前缘》等发表的文献为研究对象,利用Endnote、Excel和VOSviewer等软件对数据进行相应的整理和清洗,分析了相关热点与关键词的耦合关系。结果显示:在成矿时代同位素定年的研究中,Lu-Hf年代学逐渐成为地学研究的热点;随着测试分析手段的进步,西藏地区作为研究青藏高原前寒武纪-早古生代演化历史的关键,逐渐成为当下国内外研究热点地区;随着信息技术的发展,地学研究的数据化、信息化已成为地质学研究的热门方向。

This paper selects the authoritative journals in the field of geology from January 2016 to July 2021:the literatures published in《Acta Geologica Sinica》《Acta Petrologica Sinica》and《Geoscience Frontiers》are selected as the research objects.The data are sorted out and cleaned by using Endnote,Excel and VOSviewer software,and the coupling relationship between relevant hot spots and keywords is analyzed.The results show that Lu-Hf chronology has gradually become a hot spot in the study of isotope dating of ore-forming ages.With the progress of testing and analysis methods,the Tibetan region,as the key to the study of the Precambrian to Early Paleozoic evolution history of the Qinghai-Tibet Plateau,has gradually become a hot research area at home and abroad.With the development of information technology,the datamation and informationization of geoscience research has become a popular direction.
