摘　　要：梳理国内外土壤重金属污染研究前沿领域、研究热点,为未来土壤重金属污染研究提供科学参考。基于Webof Science和CNKI数据库,采用文献计量检索分析方法,收集土壤重金属污染研究相关文献1135篇,分析了2000~2021年全球土壤重金属污染研究的发文量、研究热点及研究趋势、土壤重金属元素关注度及研究方法。结果表明:近22年来,国内外发文量呈逐年增长态势,增长率在7700%~8300%间;基于GIS空间分析技术的土壤重金属空间分布格局、源解析成为土壤重金属污染研究的热点,土壤重金属污染对人体的危害逐渐成为土壤重金属污染研究的聚焦点;文献中对土壤重金属元素Cd、As、Pb、Cr、Cu、Zn、Hg和Ni的关注度较高,各个元素国内外研究总频次超过500;文献中单因子污染指数法是国内、外土壤重金属污染研究中应用频次较高的研究方法,其应用频次分别为592、262,潜在生态危害指数法、地积累指数法、GIS空间分析技术、内梅罗综合污染指数法的应用频次均超过150。土壤重金属的空间分布特征与源解析是当前国内外土壤重金属污染研究的重点,运用多种研究方法对土壤重金属元素进行综合分析是未来的研究趋势,国内今后要加强土壤重金属污染对人体健康影响的研究。The research frontier fields and research hotspots of soil heavy metal pollution at home and abroad were reviewed to provide scientific reference for future research on soil heavy metal pollution.Based on Web of Science and CNKI databases,1135 literatures related to soil heavy metal pollution research were collected by bibliometric search and analysis methods,and the number of published papers,research hotspots and research trends,soil heavy metal pollution research in the world from 2000 to 2021 were analyzed.The results show that in the past 22 years,the number of published papers at home and abroad has been increasing year by year,and the growth rate is between 7700%and 8300%.The spatial distribution patterns and source analysis of heavy metals in soil based on GIS spatial analysis technology have become a hotspot in soil heavy metal pollution research.The harm of pollution to human body has gradually become the focus of soil heavy metal pollution research;the literature has paid more attention to soil heavy metal elements Cd,As,Pb,Cr,Cu,Zn,Hg and Ni,and the total frequency of domestic and foreign research on each element exceeds 500;the single-factor pollution index method in the literature is a research method with high application frequency in domestic and foreign soil heavy metal pollution research,and its application frequency is 592 and 262 respectively.The frequency of application of the Nemerow comprehensive pollution index method is more than 150.The spatial distribution characteristics and source analysis of soil heavy metals are the focus of the current research on soil heavy metal pollution at home and abroad.It is a future research trend to use a variety of research methods to comprehensively analyze soil heavy metal elements.Research on the effect of soil heavy metal pollution on human health will be strengthened in China.
