基于Web of Science对土壤重金属污染修复研究的计量分析

Bibliometric Analysis of Studies on Remediation of Heavy Metals Contaminated Soils Based on Web of Science

为了解国内外土壤重金属污染修复技术的最新研究进展、研究热点及发展趋势,通过Web of Science^(TM)核心合集数据库,利用Web of Science(简称WOS)数据库自带的分析工具、Hist Cite引文图谱分析软件、VOSviewer可视化分析软件和Origin 9.1作图软件,从发文量TOP10的国家(地区)、高产作者、来源期刊、重要研究机构、研究方向热点等方面对21世纪以来(2000—2016年间)发表的有关土壤重金属污染修复研究文献进行计量分析。结果表明:该领域研究中国发文量第一,但均篇被引次数较低;高产作者主要来自美国和中国,前三名分别为美国作者Ma L Q、比利时作者Vangronsveld J和中国作者Zhou Q X(周启星);重要研究机构前三名为中国科学院、浙江大学和美国佛罗里达大学;主要期刊有Environmental Science&Technology、Journal of Hazardous Materials、Chemosphere和Environmental Pollution等;主要研究热点是植物修复技术以及生物修复、固化/稳定化修复技术;主要研究的土壤重金属对象是镉(Cd)、铅(Pb)、铜(Cu)、锌(Zn)、类重金属砷(As)等;研究主要涉及的学科是环境科学、生态学、工程学、农学和水资源学等。本文对该领域初学者了解该领域研究方向、发展趋势和研究热点具有指导意义。

【Objective】In order to get a deep understanding of progress, highlights and trend of the researches on technologies for remediation of heavy metals contaminated soils in the world, a study was carried out on bibliometric analysis of the researches in these aspects.【Method】In this study, based on the Web of ScienceTM core collection database bibliometric analysis was performed of the articles, published during the period of 2000—2016, on remediation of heavy metals contaminated soils from the aspects of countries or regions listed as TOP10 in volume of publications of related topics, high-yield authors, source journals, important research institutions and research direction or hot spots, etc. using the analysis tools self-provided by the Web of Science（abbreviated as WOS）, Hist Cite citation analysis software, VOSviewer software and Origin 9.1 software. The Hist Cite citation analysis software is a literature citation analysis tool, capable of quickly mapping out development of a research area through data analysis and enabling you to find important literature and academic bull; the VOSviewer software, a software tool for constructing and visualizing bibliometric networks and the Origin 9.1 software, one of the professional cartographic software and data analysis software and a brainchild of the Origin Lab Company.【Result】 Results show that in this research field, China ranks first in volume of publications, but quite low in frequency of citation per paper; the USA and China are homes to most of the high-yield authors, among whom the top three authors are Dr. Ma L Q in the USA, Dr. Vangronsveld J in Belgium and Dr. Zhou, Q X in China; and the Chinese Academy of Sciences, the Zhejiang University and the University of Florida are the top 3 of the most important contribution institutions; the Environmental Science Technology, the Journal of Hazardous Materials, the Chemosphere and Environmental Pollution, etc. are the most important publishers of the papers in ths field; technologies of phytoremediation, bioremediation and Stabilization/Immobilization are the hotspots in the researches; soil heavy metal pollutants, such as cadmium（Cd）, lead（Pb）, copper（Cu）, zinc（Zn） and arsenic（As）, etc. are the main objects of the researches; and environmental science, ecology, engineering science, agricultural science, water resourcescience, etc.are the major relevant disciplines of science involved.【Conclusion】This study will help beginners in this field to understand directions, trend and hotspots of the researches in this field of remediation of heavy metals contaminated soils.
