基于文献计量学国内外土壤铅污染研究状况分析

Analysis of Soil Lead Pollution Around the World Based on Bibliometrics

目的:深入了解土壤铅污染研究的现状和发展趋势,为该领域的研究人员提供参考。方法:采用文献计量学方法,利用Web of Science TM引文数据库和Citespace软件,对2010~2019年间发表的有关土壤铅污染文献进行计量分析。结果:近10年来,有关土壤铅污染的发文量呈上升趋势,中国发文量最多,德国、日本、美国与各国合作较为密切;该领域综述类论文较难发表在权威期刊,Science of the Total Environment、Chemosphere、Environmental Pollution是研究论文学术水平和影响力较高的刊物,土壤铅污染复合研究的重金属包括锌、铜、镉;主要研究热点包括铅及有关重金属形态分布、累积、健康风险评估、微量元素分析和植物修复等。结论:今后应加强土壤铅污染修复和风险评估研究。

Objective:To display the current status and development trends of soil lead pollution research deeply,and provide new information resources for researchers in this field.Methods:Using bibliometrics method,Web of Science TM citation database and Citespace software,We conduct a quantitative analysis of the literature on soil lead pollution published from 2010 to 2019.Results:The results show that the number of articles on soil lead pollution has been on the rise in the past 10 years.China has the largest number of articles,and Germany,Japan and the United States have cooperated more closely with each other.Science of the Total Environment,Chemosphere,and Environmental Pollution are journals with high academic level and influence of research papers.The heavy metals in the composite study of soil lead pollution are zinc,copper,and cadmium;the main research hotspots are the morphological distribution,accumulation,and health risk assessment of lead-related heavy metals,trace element analysis and phytoremediation.Conclusion:In the future,researchers should strengthen soil lead pollution remediation and risk assessment research.
