基于Web of Science数据库,利用文献计量学方法分析1977─2014年生态系统碳交换研究的有关文献年际变化和学科分布,重点研究分析2010─2014年相关文献的研究力量以及合作状况。结果表明,(1)生态系统碳交换是一个多学科交叉的研究领域,自1977年出现了第一篇有关生态系统碳交换的论文之后,文献数量除个别年份略有波动之外,整体呈稳步增长趋势。(2)发表生态系统碳交换相关文献较多的前15种出版物中,发文量最多的是Agricultural and Forest Meteorology;Global Change Biology、Agricultural and Forest Meteorology、Journal of Geophysical Research-Biogeosciences和Biogeosciences的论文总被引频次较高,均超过了1000次。(3)从发文量、总被引次数和高被引论文篇数来看,美国、德国、加拿大和法国等生态系统碳交换研究论文综合影响力较高;Chinese Acad Sci、Max Planck Inst Biogeochem、Harvard Univ和Univ Calif Berkeley等机构的论文综合影响力较高;从篇均被引频次和高被引论文所占比例来看,瑞士、荷兰、比利时、意大利和法国等国的论文质量较高;Univ Calif Berkeley、Harvard Univ和Max Planck Inst Biogeochem等机构的论文质量较高。虽然中国在发文量上排第二位,但在篇均被引频次、高被引论文数及其所占比例等指标上并无优势。(4)国家、机构和作者层面的合作度都呈现波动变化,但变化幅度并不大,呈稳定态。
英文摘要:
Based on the online version of Web of Science, the interannual variation and subject distribution on ecosystem carbon exchange published papers from 1977 to 2014 was analysed using the bibliometrics method. The research effort and corporative state from 2010 to 2014 was focused. Result showed that:(1) Theecosystem carbon exchange is a interdisciplinary research field. The first paper on ecosystem carbon exchange appears in 1977. The number of papers showed a trend of steady growth as a whole. (2) In this field, journal with high number of published papers include Agricultural and Forest Meteorology. The cited frequency was more than 1000 in these journals such as Global Change Biology、Agricultural and Forest Meteorology、Journal of Geophysical Research-Biogeosciences and Biogeosciences. (3) According to the number of papers, citation frequency and the number of highly cited papers, the country with higher comprehensive influenceincluded America, Germany, Canada and French in the field; the organization with higher comprehensive influence included Chinese AcadSci, Max Planck Inst Biogeochem, Harvard Univ and Univ Calif Berkeley. According to average citation per paper and the proportion of highly cited papers, the quality of papers is higher in these countries such as Switzerland, Netherlands, Belgium, Italy and French, as well as in these organization such as Univ Calif Berkeley, Harvard Univ and Max Planck Inst Biogeochem. Although China is the second in the number of papers, but it is no advantage on average citation per paper, the number and proportion of highly cited papers. (4) There was a fluctuation variation in the cooperation degree among countries, organizations and authors. It indicates that the research scale is stable state, and the symbiosis is intimate in the field.
