摘要

摘要:
基于Web of Science（WoS）核心合集数据库和中国知网（CNKI），采用文献计量学方法和可视化分析软件揭示国内外重金属污染土壤修复材料研究领域近20年来的发展脉络、研究热点及发展方向。结果显示，相较于2001—2004年，2013—2016年和2017—2020年重金属污染土壤修复材料研究领域发文量显著增加，增长率分别为1 302%和2 201%。我国在该领域研究起步较晚，但发展迅速。关键词热点分析显示，当前污染修复研究侧重于农田土壤修复治理，重金属镉、铅及钝化材料应用。关键词聚类分析显示，钝化材料筛选和应用是当前热点主题，其中钝化材料修复机理和效果评估是该主题的重点和难点。当前农田土壤重金属污染修复材料研究正处于快速发展时期，钝化材料的功能化改性及其在农田应用中的研究有望取得较好的修复成效，绿色无污染和安全可持续的修复材料研发和应用是当下及未来的研究热点。

Abstract:
Based on the database of Web of Science (WoS) Core Collection and China National Knowledge Infrastructure (CNKI), the literature in the past 20 years was searched by using literature metrology and visual analysis software to reveal the development context, research hotspots and development direction of the research field of heavy metal contaminated soil remediation materials at home and abroad. The results showed that compared with 2001-2004, the number of articles published in the field of heavy metal contaminated soil remediation materials in 2013-2016 and 2017-2020 increased significantly by 1302% and 2201% respectively, showing rapid growth. Compared with foreign research, although China started late in this field, it had developed rapidly. Keywords hot spot analysis showed current pollution remediation research focused on remediation of farmland soil, remediation of heavy metals cadmium and lead, and application of immobilized materials. Through keywords cluster analysis, screening and application of immobilized materials was a hot topic of current research, especially the repair mechanism and effect evaluation of immobilized materials were the focus and difficulty of this topic. At present, research on remediation materials for heavy metal pollution in farmland is developing rapidly and functional modification of immobilized materials and their application in farmland are expected to achieve good results in remediation. Moreover, the research and development and application of "green pollution-free" and "safe and sustainable" remediation materials are becoming a research hotspot at present and in the future.
