基于文献计量的土壤污染研究趋势分析

Trends of Soil Pollution Research Based on Bibliometric Analysis

为了解全球在土壤污染方面的研究趋势,以2000—2019年的Web of Science数据库及其扩展数据库中有关土壤污染的科学论文为研究对象,借助文献计量学方法分析研究动态。结果表明:世界范围内相关发文量总体呈逐年上升趋势,美国和中国在该领域的发文数量领先于全球其他国家和地区,分别占发文总数的19.70%和18.93%;中国科学院系统发文量最多,浙江大学以1598篇位居第5;华人研究者高被引的论文在世界范围内最多,前20名中占有11名,其中有3位来自于湖南大学;重金属成为土壤主要污染物,未来土壤修复热点将集中在植物修复、微生物修复、无机矿物修复和联合修复技术等方面。

The global research trends in soil pollution were analyzed with the help of bibliometrics with scientific papers on soil pollution in the Web of Science database and its extended database from 2000 to 2019 as the research objects.The findings suggest that the number of published papers worldwide is generally increasing year by year.The number of papers by the United States and China in this field is ahead of other countries and regions around the world,accounting for 19.70%and 18.93%of the total number,respectively.The Chinese Academy of Sciences boasts the largest number of papers,while Zhejiang University ranks fifth with 1,598 papers.Chinese researchers have the most highly cited papers in the world,11 of top 20,of which three are from Hunan University.As heavy metals have become one of the major contaminants in porous soil systems,the future hot spots for soil remediation will focus on phytoremediation,microbial remediation,inorganic mineral remediation,and joint repair technologies.
