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.%Based on data from ISI Web of Science database,we investigated the research topics in deep-time research since 1900. By analyzing the number of research articles, countries of authors, the themes and authors countries of Top 5% highly cited papers,we try to reveal the research focus and the international influence of Chinese scholars in the deep-time paleoclimate research filed. Our data shows that deep-time research has keep growing rapidly since 1990. The deep-time research mainly focuses on the paleoceanographic events,mass extinctions and their relationship to palaeoclimate,the palaeoclimate change(temperature,pCO2,etc.);Although the sum of research papers is con-cerned,China has become one of important contributors to deep-time climate research. However, the proportion of Chinese highly influential research is still very low.
