基于文献计量法对场地土壤重金属污染修复研究进展的知识图谱分析

Knowledge Graph Analysis of the Remediation Research Progress for Heavy Metal Contaminated Soil Based on Bibliometric Method

  • 摘要: 为全面了解国内外场地土壤重金属污染修复领域的研究现状及前沿动态,利用CiteSpace软件对该领域的相关文献进行可视化分析。结果表明:该研究领域近12年来中外文文献发文量呈波动式增长态势,中国、美国、印度、意大利、波兰等是外文文献发文量较多的国家。该领域主要发文机构有中国科学院、中国科学院大学、浙江大学、贝尔格莱德大学、波兰科学院等,其中中国科学院占据重要地位,表明我国在该研究领域有较强的学术影响力和较为显著的贡献。从合作关系方面分析,该领域国内外作者自身科研团队内部合作紧密,但团队之间的交流合作显得不足。从关键词及聚类图分析可知,该领域研究进展分为三个阶段:第一阶段研究主题侧重于单一重金属元素在场地土壤中的变化,第二阶段侧重于污染物定性定量分析及风险评估,第三阶段侧重研发新型修复材料及通过构建模型进行风险评价。根据时区图、突现图以及研究路径可知,“源解析-重金属空间分布-联合修复技术、新型修复材料-健康风险评价”这一路径可作为该领域的研究热点及前沿。

     

    Abstract: In order to comprehensively understand the research status, research progress and frontier trends of soil heavy metal pollution remediation research at home and abroad, CiteSpace software was used to visualize and analyze the literature in the field of site soil heavy metal pollution remediation in this article. The results showed that the number of literature published in Chinese and foreign languages in this research field has shown a fluctuating growth trend in the past 12 years. China, the United States, India, Italy, Poland, etc. were countries with a large number of foreign language literature. The main publishing institutions in this field included the Chinese Academy of Sciences, the University of the Chinese Academy of Sciences, Zhejiang University, the University of Belgrade, the Polish Academy of Sciences, etc. Among them, the Chinese Academy of Sciences occupied an important position, indicating that China has a strong academic influence and significant contributions in this research field. From the perspective of cooperative relations, authors at home and abroad in this field cooperate closely within their own scientific research teams, but lack communication and cooperation between teams. From the analysis of keywords and cluster maps, it can be seen that the research progress in this field is divided into three stages. The first phase focused on the changes of a single heavy metal element in the soil of the site, and the second phase focused on qualitative and quantitative analysis and risk assessment of pollutants. The third phase focused on the research and development of new repair materials and risk assessment through the construction of models. According to the time zone map, emergent map and research path, the path of "source analysis - spatial distribution of heavy metals - joint repair technology, new repair materials - health risk assessment" can be used as the research hotspot and frontier in this field.
