冷泉系统研究国际发展态势分析

Trends and hot spots in international cold seep research

以 Web of Science信息平台的 SCIE数据库为数据源,利用文献计量方法,分析国际冷泉系统研究的年度变化、期刊分布、主要研究国家、机构的影响力及合作情况以及国际研究热点领域。研究结果发现:国际冷泉系统研究论文产量一直呈增长趋势;美国论文产出数量最多、合作中心性最强。德国亥姆霍兹国家研究中心联合会发文最多。中国近三年发文比例和第一国家发文比例均排名第一,其中发文最多的机构为中国科学院。微生物甲烷厌氧氧化、冷泉区生物多样性以及冷泉碳酸盐岩的矿物学和地球化学是研究热点。

On the basis of the data from the informaiton platform of the Web of Science batabaseand through the use of the bibliometrics method, the annual journal distribution, maincountries and its influence, international institutions, andfocus research realms are compared and analyzed.Results shows that the number of international cold seepresearch papers has been increasing. The USA is well ahead of other countries in the total number of publications and serves as the cooperative center between countries. In the past 3 years, the number of publications from- China is higherthan that from other countries. The first author countrypercentageof China is also higher than that of other countries. The institution with most numberof publications is the Chinese Academy of Sciences. Furthermore, the microbial anaerobic oxidation of methane, biodiversity of cold seep, and mineralogy and geochemistry of cold seep carbonate are the research hotspots.
