基于Web of Science大数据的土壤环境中多环芳烃研究文献计量分析

A Bibliometric Analysis of Researches on Polycyclic Aromatic Hydrocarbons in Soil Environment Based on Web of Science

为深入了解土壤环境中多环芳烃研究的全球状况和前沿动态,客观反映相关国家和机构在该领域的科学能力和影响,采用ISI Web of Knowledge的Web of Science引文数据库,对1990-2014年间该库收录的土壤环境中多环芳烃研究领域的相关文献进行了计量分析。结果表明,该领域发文量呈快速持续上升趋势;美国发文量居榜首,中国及其研究机构近年来发文量飞速增长,但整体篇均被引频次明显偏低;该领域的主要期刊有Chemosphere、Environmental Science＆Technology、Environmental Pollution等;未来该领域的研究热点依然集中于土壤环境中多环芳烃的降解及生物修复。

To better understand the global status and trend of researches on polycyclic aromatic hydrocarbons（PAHs） in soil and to reflect their scientific capabilities and influences of relevant nations and institutions,a bibliometric analysis on related literatures published in the period of 1990~2014 has been conducted by means of SCI database of Web of Science based on ISI Web of Knowledge.Results indicated that the number of related publications took a steadily rising trend,in which the United States ranked first accounting for 20.75%of all worldwide,whilst Chinese institutions had published a rapidly increasing number of related articles in recent years but the frequency of their citation was apparently on the low side.Top journals in the field included Chemosphere,Environmental Science Technology,Environmental Pollution,and etc.In future,the hot topics in the field would still be focused on the degradation and bioremediation of PAHs in soil environment.
