植物修复研究的知识谱图分析

为了解有关植物修复研究领域的研究热点、发展趋势、核心作者及研究机构,通过检索1999~2020(3.18)年共21年CNKI数据库中有关植物修复研究的文献,利用CiteSpace软件绘制关于植物修复研究的知识谱图,并进行文献可视化分析。结果表明:近21年来该研究领域发文数量呈波动式增长态势;我国植物修复研究近年来主要分布在重金属污染修复领域,以重金属污染、土壤、黑麦草、生态修复、超富集植物等为主要关键词;骆永明、吴龙华、周启星、陈同斌、林立金、王丹等是主要发文作者;我国植物修复研究近年来呈局部集中,总体分散的特征,主要研究机构为西南科技大学生命科学与工程学院、中国科学院大学/中国科学院研究生院、中国科学院南京土壤研究所等;我国植物修复研究自1999年开始,1999~2003年为起步初探阶段,2004~2015年为稳定发展阶段,2016~2020(3.18)为快速增长阶段。研究为我国未来植物修复研究提供了一定的借鉴和指导。

Knowledge Spectrum Analysis of Phytoremediation Research

In order to understand the research hotspots,development trends,core authors and research institutions in the field of phytoremediation,this paper searched the literature of phytoremediation research in CNKI database for 21 years from 1999 to 2020(March 18),CiteSpace software was used to drew the knowledge spectrum of phytoremediation research,and literature visualization analysis was conducted.The results showed that in recent 21 years,the number of papers published in this research field showed a fluctuating growth trend;in recent years,the research of Phytoremediation in China was mainly distributed in the field of heavy metal pollution remediation.Taking heavy metal pollution,soil,ryegrass,ecological remediation and super enrichment plants as the main keywords,Luo Yongming,Wu Longhua,Zhou Qixing,Chen Tongbin,Lin Lijin,Wang Dan,etc.were the main author.In recent years,the research on Phytoremediation in China is characterized by local concentration and overall dispersion,the main research institutions are Life Science and Engineering College of Southwest University of Science and Technology,University of Chinese Academy of Sciences/Graduate School of Chinese Academy of Sciences,Institute of Soil Science,Chinese Academy of Sciences,etc.;Phytoremediation research in China started in 1999,the initial stage was from 1999 to 2003 the stable development stage was from 2004 to 2015,,and the rapid growth stage was from 2016 to 2020(March 18).This study provides some reference and guidance for the future research of Phytoremediation in China.
