發(fā)布時間:2019-03-04 15:00
【摘要】:以ISI Web of Science論文數(shù)據(jù)庫為數(shù)據(jù)源,針對1900—2016年國際深時氣候領(lǐng)域發(fā)表的論文,從文獻計量學(xué)的角度,統(tǒng)計分析了論文發(fā)表的數(shù)量、國家以及國際Top 5%論文的主題和作者,著重分析當前古氣候領(lǐng)域的研究熱點以及我國在這一領(lǐng)域的影響力情況。結(jié)果顯示:自20世紀90年代以來國際深時氣候領(lǐng)域論文數(shù)量持續(xù)增長;國際古氣候研究主要集中于古海洋事件、生物大滅絕事件與氣候的聯(lián)系、氣候變化等方向;雖然按論文產(chǎn)出量排序,中國已進入深時氣候研究的前列,但高影響研究成果的比例仍非常低。
[Abstract]:Taking the ISI Web of Science paper as the data source, and aiming at the papers published in the international deep-time climate field of 1900 to 2016, the paper makes a statistical analysis of the number of papers published, the subject and the author of the international Top 5% paper from the perspective of the bibliometrics. The research focus on the current paleoclimatic field and the influence of our country in this field are analyzed. The results show that, since the 1990s, the number of papers in the international climate field has continued to increase, and the international paleoclimate research is mainly focused on the ancient marine events, the relationship between the event of the mass extinction and the climate, the climate change, etc., although it is ordered according to the output of the paper, China has entered the forefront of the deep-weather research, but the proportion of the high-impact research results is still very low.
