中文摘要：

以Thomson Reuters公司Web of Science信息平台提供的科学引文索引扩展版（SCIE）数据库为数据源,采用Thomson Data Analyzer（TDA）和UCINET软件对1992年1月至2016年6月SCIE收录的修饰土吸附多环芳烃（PAHs）的研究论文进行数据挖掘和定量分析。结果显示：国际上关于修饰土吸附PAHs的研究分为起初发展期（1992—2002年）、快速发展期（2003—2009年）和稳步发展期（2010—2016年）3个阶段;关键词PAHs在不同阶段均保持较高频次,随着时间推进,biodegradation的词频基本保持不变;2003—2009年,中国大陆研究论文数量开始超过美国,成为研究的主要力量;3个阶段内,研究的热门方向从表面活性剂对地下水的修复逐渐向PAHs的生物降解、复配表面活性剂对PAHs在黏土上的吸附作用转变;目前研究的热点为PAHs的解吸和生物降解、对PAHs的沉积和固定作用、烃类复合污染的生物有效性,而研究区域之间的交叉研究是未来的创新点。

英文摘要：

Science Citation Index Expanded （SCIE） database provided by Web of Science information platform of Thomson Reuters was selected as the data source,data mining and quantitative analysis of papers on polycyclic aro-matic hydrocarbons （PAHs） adsorption by modified soil were carried out by Thomson Data Analyzer （TDA） and UCINET from January 1992 to June 2016 in the SCIE database. Results showed that international studies of PAHs adsorption by modified soil could be divided into three stages, which were initial development period （1992-2002） ,fast development period （2003-2009） and steady development stage （2010-2016）. Keywords with higher frequency in three stages were PAHs. As time went on, word frequency of biodegradation remained unchanged basically. From 2003 to 2009 , the amount of papers in China mainland had began more than the United States,and China mainland became the main forces of research. The popular research direction gradually changed from surfactants on groundwater repair to biodegradation of PAHs and adsorption of PAHs on clay by compound surfactant. The current research hotspots were desorption and biodegradation of PAHs,deposition and fixation of PAHs,and biological effectiveness of hydrocarbon compound pollutions. The cross-over studies between the internal and external research were the innovation and devel-opment direction of the future researches.
