为探析国内外生物炭修复重金属污染研究领域的研究态势,采用文献计量学方法,对 2002-2021 年间生物炭修复重金属污染研究领域的国内外文献进行全景扫描,从发文量、研究力量和关键词三个维度,利用Cite Space和VOS viewers软件对这一领域的研究态势进行可视化呈现,进而探析该领域的热门研究主题.结果表明:国内外该领域的研究论文数量总体呈上升趋势,中国是该领域发文量最多的国家,中国科学院和巴基斯坦的费萨拉巴德农业大学是该领域的核心研究机构;生物炭及其复合材料的制备与应用、生物炭对重金属污染水土的修复方法和修复机理以及环境效益是当前该领域中外文文献的研究热点;生物炭的原位修复、生物炭对重金属的固定技术与效果分别是未来中外文文献的研究方向.
In order to explore the research trend in the field of heavy metal pollution remediation by biochar at home and abroad,the literature metrology method was used to conduct a panoramic scan of the domestic and foreign literature in the field of heavy metal pollution remediation by biochar from 2002 to 2021.From the three dimensions of the number of papers,research strength and keywords,Cite Space and VOS viewers software were used to visualize the research trend in this field,and then explore the hot research topics in this field.The results show that the number of research papers in this field at home and abroad is on the rise.China is the country with the largest number of papers in this field,and the Chinese Academy of Sciences and Pakistan's Faisalabad Agricultural University are the core research institutions in this field.The preparation and application of biochar and its composite materials,the remediation methods and mechanisms of biochar for heavy metal contaminated soil and water,and environmental benefits are currently research hotspots in foreign literature in this field.The in-situ remediation of biochar and the fixation technology and effect of biochar on heavy metals are the research directions of future Chinese and foreign literature,respectively.
