基于Web of Science数据库的土壤生物修复研究趋势分析

土壤生物修复技术因其成本低、不易造成二次污染，已成为世界各国研究的热点。应用文献计量学方法分析土壤生物修复领域的研究现状及发展趋势，对Web of Science核心数据库中2000—2019年收录的有关土壤生物修复的25174篇论文进行了统计分析。结果表明:中国在该领域虽起步较晚，但发展迅速，成为发文量最高的国家（3680篇），发文机构中中国科学院占据发文量榜首，且被引次数最多。Chemosphere是该领域发文量最多的期刊（963篇），Science of the Total Environment期刊近几年发展最为迅速；土壤生物修复的最新研究热点集中在微生物群落、基因测序、代谢途径分析以及新材料等方面。

TREND ANALYSIS OF SOIL BIOREMEDIATION BASED ON WEB OF SCIENCE DATABASE

Soil bioremediation technology has become a research hotspot in the world because of its low cost and no secondary pollution. The article applied bibliometric methods to analyze the research status and development direction in the field of soil bioremediation, and provided reference for subsequent research. A statistical analysis was carried out based on 25174 papers on soil bioremediation included in the core database of Web of Science from 2000 to 2019. The results showed that although China started late in this field, it developed rapidly and became the country with the highest number of publications (3680). Among the publishing organizations, the Chinese Academy of Sciences had the highest number of publications and citation. Chemosphere was the journal with the most publications in this field (963). The journal Science of the Total Environment developed the fastest in recent years; the latest research hotspots in soil bioremediation were focused on microbial communities, gene sequencing, metabolic pathway analysis, and new materials innovation.
