摘要
为了解国内土壤镉砷污染修复技术研究现状和未来发展趋势,采用文献计量方法和可视化软件Citespace,结合关键词检索统计方法,使用CNKI全文数据库,检索1999—2019年土壤镉(Cd)和砷(As)污染修复技术相关论文15301篇,并绘制了网络知识图谱。结果表明:1999—2012年为镉砷污染土壤修复技术文章低发期,2013—2015年发文量跌宕增长;2016—2019年我国镉砷污染土壤修复技术步入了快速发展阶段;在我国土壤镉砷修复领域研究中,植物修复是热点修复手段之一;从研究机构的分布来看,南北方有较大差异,南方地区的发文量大于北方地区。在此基础上,对未来镉砷污染土壤修复技术和发展方向进行了预测分析。可以看出,我国应不断发展多手段结合的联合修复技术,做好土壤镉砷污染修复预警与风险防控仍是未来的工作重点。以上分析结果可为镉砷污染土壤的修复提供借鉴和参考。
In order to understand the research status and future development trend of soil cadmium and arsenic remediation technology in China,a total of 15301 papers related to soil cadmium(Cd)and arsenic(As)remediation technology from 1999 to 2019 were retrieved from the CNKI database by using bibliometrics and visual software Citespace in combination with keyword retrieval statistics method,and the network knowledge map was drawn.The results showed that from 1999 to 2012,the number of articles about remediation techniques for soil pollution with cadmium and arsenic was low.From 2013 to 2015,the number of articles showed a fluctuationally rise trend.From 2016 to 2019,the remediation technologies for China’s cadmium and arsenic contaminated soil entered a stage of rapid development.Phytoremediation was one of the hot remediation methods in the field of soil cadmium and arsenic remediation in China.Besides,the distribution of research institutions varies greatly from north China to south,and the volume of published papers by the authors in south China was larger than those in the north China.On the basis of above study,this paper predicts and analyzes the future remediation technologies and development directions for soils polluted by cadmium and arsenic:the joint remediation technologies combining multiple means should be continuously developed by China,the key tasks in the future will be to do a good job in early warning and risk prevention and control in soil cadmium and arsenic pollution remediation.The results provide reference for the remediation of cadmium-arsenic contaminated soil.
