以ISI Web of Science论文数据库为数据源,针对1900—2016年国际深时气候领域发表的论文,从文献计量学的角度,统计分析了论文发表的数量、国家以及国际Top 5%论文的主题和作者,着重分析当前古气候领域的研究热点以及我国在这一领域的影响力情况。结果显示:自20世纪90年代以来国际深时气候领域论文数量持续增长;国际古气候研究主要集中于古海洋事件、生物大灭绝事件与气候的联系、气候变化等方向;虽然按论文产出量排序,中国已进入深时气候研究的前列,但高影响研究成果的比例仍非常低。
Taking the ISI Web of Science paper as a data source and the paper published in the field of deep-seated climate in the world from 1900 to 2016, from the perspective of bibliometrics, this paper statistically analyzes the number of papers published, the topics of the national and top 5% international papers The author focuses on the current research hotspots in the paleoclimate field and the influence of our country in this field. The results show that: since the 1990s, the number of papers in the field of deep-seated climate in the world has continued to grow; the international paleoclimate research has mainly focused on the paleoceanographic events, the connection between the mass exocution and the climate, and climate change; Ranking, China has entered the forefront of deep-climate research, but the proportion of high-impact research results is still very low.
