为了解浮萍领域的研究分布与研究现状,对1925-2013年SCI收录的浮萍(duckweed)研究文献进行了分析,结果表明:共检索到浮萍研究论文1 742篇,年发文量总体呈增长趋势,1990年后年发文量与论文总被引次数显著升高;美国无论发文量、总被引频次和H指数都远超过其他国家,排名第一,综合体现了美国在浮萍研究的主导地位;中国在总发文量居第五位;刊载文献最多的期刊是美国的《Environmental Toxicology and Chemistry》;浮萍研究方向主要分布在环境科学与生态、植物科学、毒理学方面;研究热点主要集中在浮萍对生活污水和工业污水的净化效应方面。

Bibliometrics Evaluation of the Duckweed Scientific Papers Based on Web of Science

In order to investigate the distribution and current status of duckweed study, this paper analyzed the duckweed research literature collected by Science Citation Index expand（SCIE） since 1925 to 2013. The results indicated that there were 1 742 research papers indexed, and the annual quantity of paper issued showed a growing trend. After 1990, the quantity of paper issued and citation frequency was remarkably increased. The United States ranked No.1 in the 3 aspects of paper quantity, citation frequency and H\|index, which embodied that USA took the leading position in duckweed research area. China took No.5 in issued paper quantity. The periodical with the largest quantity of research papers was . Duckweed literatures are mainly distributed in Environmental Sciences and Ecology, Plant Sciences, Toxicology. The research hot spots are constructed in the purification effects of duckweed in sanitary sewage and industrial waste water.
