摘要
植物修复是去除重金属污染最具前景的修复手段之一.为全面了解和掌握重金属污染植物修复的研究现状以及发展趋势,检索了2000年1月1日—2024年4月30日期间中国知网(CNKI)数据库和Web of Science(WOS)核心数据库中关于重金属植物修复的相关文献,使用CiteSpace软件绘制重金属植物修复研究的知识图谱,从发文量、核心作者、研究机构、关键词和突现词等方面进行文献可视化分析.研究结果表明:自21世纪以来,重金属植物修复研究领域发文数量呈现增长态势,重金属植物修复正逐渐成为我国的研究热点;中国科学院土壤研究所的部分学者之间联系较为紧密,是重金属植物修复领域的核心学者;在发文机构统计方面,中南林业科技大学、南京农业大学、四川农业大学、湖南农业大学、中国科学院研究生院、西北农林科技大学、浙江大学等科研院所占据主要地位,并具有较强的影响力,但与国际研究机构相比,国内大学和研究所之间仍需强化学术交流和学术合作;重金属植物修复研究主要聚焦于土壤重金属污染,其中以生物修复、cadmium、phytoremediation等为主要研究内容;近五年重金属植物修复研究聚焦于利用“联合修复”“生态修复”和“植物内生菌”等手段来提高重金属污染植物修复的效率,进一步促进重金属植物修复技术的发展及实际应用.此研究有助于全面了解目前我国重金属植物修复技术的研究趋势,可为重金属植物修复的研究提供一定的参考和借鉴.
Phytoremediation is one of the most promising remediation methods to remove heavy metal pollution.In order to comprehensively understand and grasp the current research status,as well as the development trend of phytoremediation for heavy metal pollution,this paper studies the relevant literature on heavy metal phytoremediation in the CNKI and WOS databases from January 1st,2000 to April 30th,2024.The study utilizes CiteSpace software to generate a knowledge map of heavy metal phytoremediation research and analyzes the literature visualization and analysis,including the number of articles issued,core authors,research institutions,keywords,and burst detection.The results show that since the 21st century,a number of publications in the field of heavy metal phytoremediation has shown an increasing trend,and that heavy metal phytoremediation is gradually becoming a hot research topic in China.The scholars from the Institute of Soil Science,Chinese Academy of Sciences are closely connected with each other and are the core scholars in the field of phytoremediation of heavy metals.In terms of the statistics of publishing institutions,Central South University of Forestry and Science and Technology,Nanjing Agricultural University,Sichuan Agricultural University,Hunan Agricultural University,Graduate School of Chinese Academy of Sciences,Northwest A&F University,Zhejiang University and other research institutions occupy a major position and have a strong influence.However,compared with international research institutes,there is still a need to strengthen academic exchanges and cooperation among domestic universities and research institutes.Heavy metal phytoremediation research mainly focuses on heavy metal contamination in soil media,with bioremediation,cadmium,and phytoremediation as the main research components.In the past five years,heavy metal phytoremediation research has focused on improving the efficiency of heavy metal contamination phytoremediation by means of“combined remediation”,“ecological remediation”and“endophytes”.The development and practical application of heavy metal phytoremediation technology are furtherly promoted.This study contributes to a comprehensive understanding of the current research trend of heavy metal phytoremediation technology in China,and provides a certain reference and reference for the research of heavy metal phytoremediation.
