摘要
基于Web of Science和中国知网(CNKI)的数据源,选择对应数据库、设定年限,检索相关文献和专利,运用文献计量学方法,并借助Origin、Excel等绘图制表工具对数据结果进行了统计、分析和对比,比较直观地展现出重金属污染土壤氧化还原修复技术的总体情况、国内外发展现状和趋势、国内外发展差距,并从关键词的发展演替角度分析研究热点与方向,为氧化还原修复技术相关学科发展与研究等提供决策参考。
In this paper, on the basis of Web of Science and CNKI data source, relevant literatures and patents are retrieved by means of selecting corresponding database and setting years range. Bibliometric is used to count, analyze and compare the collected data by application of Origin, Excel and other plotting and tabulating tools. The results intuitively show the overall situation of redox remediation technology for heavy metal contaminated soils, the development status, trend and differences at home and abroad. In addition, research hotspots and orientations are also analyzed from the aspect of keywords evolution, providing references for decision-making of the development and study of redox technology-related disciplines.
