【摘要】 土壤重金属污染问题一直都是环境科学的热点与前沿。为深刻了解国内外这一领域的关键主题及最新动态,本文以Web of Science和CNKI期刊数据库检索的文献数据为样本,以CiteSpace为分析平台,从国家、机构、作者、研究热点等诸多方面,对土壤重金属研究的现状及关键主题进行了可视化分析。结果表明,国际上土壤重金属研究呈现多样化趋势,并且中国占居核心地位;关键主题集中于污染物来源与分布、污染评价及污染修复三大领域;当前研究偏重于环境科学、农学、工程技术、化学、地质学、毒理学以及植物学的相关研究。预计未来土壤重金属研究将呈现国际化、多学科综合化、多技术协同化发展的趋势。更多还原

【Abstract】 Soil heavy metal pollution has always been the hotspot and frontier of environmental science. In order to understand the key topics and frontier dynamics of international and domestic research on soil heavy metal pollution, we collect the data from Web of Science and CNKI. Dividing the domestic and international research perspectives by CiteSpace which is a platform designed for clustering analysis. Focused on the authors, the research hotspots, the status quo and hotspots of the research field, and then constructed the research hotspot framework. The results showed that the research trend in soil heavy metals is internationalization. Interestingly, the most core research institutions and scholars are in China, and most of the correlation studies are focused on source/distribution, pollution evaluation, and restoration. Moreover, those studies could be assigned to Ecological environment science, Agriculture, Engineering, Chemistry, Geology, Toxicology and Botany. Furthermore, the study of soil heavy metals will be still in the trend of internationalization, multidisciplinary integration and multi-technology synergetic development in the future.更多还原
