污染农田土壤的重金属钝化技术研究——基于Web of Science数据库的计量分析

Research on Immobilization of Heavy Metals in Contaminated Agricultural Soils―Bibliometric Analysis Based on Web of Science Database

为全面直观了解全球农田土壤重金属污染钝化修复研究进展和发展趋势,本文基于Web of Science(简称WoS)核心合集数据库利用WoS数据库自带分析工具、HistCite引文图谱分析软件和VOSviewer可视化分析软件,从发文量或被引频次TOP10的国家、研究机构、作者、期刊、研究热点等方面对1990―2019年发表的农田土壤重金属污染钝化修复文献进行计量分析。结果表明,世界范围内农田土壤重金属钝化修复领域年度发文量呈逐渐增长的趋势,发文量前三的国家是中国、美国和西班牙,中国的发文量远超其他国家,占比28.79%;发文机构主要是中国科学院、西班牙高等科学研究委员会、中国科学院大学、佛罗里达大学和浙江大学等,其中中国科学院发文量和被引频次均为最高,在该领域具有显著的科研水平和影响力;主要期刊有Environmental Science and Pollution Research、Chemosphere、Science of the Total Environment和Journal of Hazardous Materials等;目前应用较多的钝化剂主要是污泥、生物质炭、赤泥、堆肥、磷酸盐、石灰、废弃物等,关注的重金属主要是镉、铅、铜、锌、砷等,主要侧重于重金属的生物有效性。

【Objective】This work was performed to understand the research status,hot spot and development trend on remediation of heavy metals in agricultural soils all over the world.Meanwhile,it could objectively reflect the academic level and international influence of relevant countries,institutions and scholars,etc.in this field.【Method】We employed the Web of Science core collection database(WoS),together with the analysis tools self-provided by WoS,HistCitecitation analysis software and VOSviewer software to conduct bibliometric analysis of the literatures on immobilization of heavy metals in agricultural soil.The data were retrieved from the literatures published during the period of 1990-2019.【Result】Results showed that a total of 3376 articles related to immobilization/stabilization of heavy metal pollution in farmland soil were retrieved,and the quantity of publications increased steadily year by year worldwide.The top three countries in number of publications are China,the United States and Spain,and China ranks first in volume of publications,accounting for 28.79%.The Chinese Academy of Sciences,Consejo Superior de Investigaciones Cientificas,University of Florida and Zhejiang University are the major paper-publishing institutions,which have remarkable scientific research level and influence in this field.Particularly,Chinese Academy of Sciences has the highest number of publications and citation frequency,publishing 224 articles with total local citation score 1276 times.Major publishers include Environmental Science and Pollution Research,Chemosphere,Science of the Total Environment,Journal of Hazardous Materials,etc.The passivants include mainly sludge,biochar,red mud,compost,phosphate,lime,and etc.And the research on metal immobilization/stabilization in agricultural soils mainly focuses on the bioavailability of heavy metals.Cadmium,lead,copper,zinc and arsenic are the main concerned heavy metals.【Conclusion】This study would help researchers in this field to grasp the development trend and hotspots accurately,and provide important insights and references for future research.
