基于文献计量的土壤环境中多环芳烃降解的研究现状

Research Status of Polycyclic Aromatic Hydrocarbon Degradation in Soil Environment Based on Bibliometrics

随着工农业的发展,化肥、农药的大量使用、石油开采、交通运输等人为活动导致土壤多环芳烃(PAHs)污染日趋严重。土壤中PAHs的污染已经成为全世界面临亟待解决的问题,有研究表明降解是去除土壤中PAHs的最主要途径。为了进一步了解土壤PAHs降解研究近况,选用Web of Science核心合集数据库,对2000—2017年间该库收录的相关文献进行了计量分析。结果表明,在世界范围内发文量总体呈上升趋势,中国的发文量居第一,美国的发文量其次;中国科学院和南京农业大学的发文量居全球研究机构的前两位;该领域的重要期刊为International Biodeterioration Biodegradation、Journal of Hazarodous Materials和Chemosphere等;同时,分析了15年间的关键词并指出PAHs降解研究的热点方向。其中中国从事的相关研究十分重要。本研究描述了世界范围内土壤环境中PAHs降解研究领域的研究现状,为中国在该领域的进一步研究提供有益参考。

With the development of industry and agriculture,human activities are leading to the increasing pollution of soil polycyclic aromatic hydrocarbons(PAHs)such as heavy use of chemical fertilizer and pesticides,oil exploitation,transportation,etc.The pollution of PAHs in soil has become an urgent problem to be solved by the world.Studies showed that degradation was the most leading way to remove PAHs from soil.To further understand recent situation of soil PAHs degradation research,relevant literatures from 2000 to 2017 were studied with quantitative analysis by selecting the collection database of the Web of Science core.The results showed that the number of published papers generally increased on a world wide scale,the number of China’s publications ranked the first,followed by that of the United States.The number of published papers by Chinese Academy of Sciences and Nanjing Agricultural University ranked the top two among global research institutions.The key journals in this field were International Biodeterioration Biodegradation,Journal of Hazarodous Materials and Chemosphere,etc.At the same time,the key words of the 15 years were analyzed and the hot direction of PAHs degradation research was pointed out.Of which,the relevant research carried out by China was extremely important.This study describes the research status in the field of PAHs degradation in soil environment worldwide,and provides certain references for further research in this field in China.
