矿山生态环境修复研究热点与前沿分析——基于VOSviewer和CiteSpace的大数据可视化研究

矿山生态环境修复作为生态文明的"绿水青山"建设的重要举措,受到越来越多学者的关注和参与。为了厘清近20年来中国矿山生态环境修复工作的热点、阶段性研究前沿、目前的研究进展,以及预测未来的研究方向,以中国知网(CNKI)为数据源,采用文献计量学方法结合VOSviewer和CiteSpace两款可视化分析软件,定量分析了2000—2018年发表的相关文献。结果表明,近20年间,矿山生态环境修复领域研究成果主要以期刊杂志形式发表,且发文量随着年份增加呈显著增长趋势;通过VOSviewer对关键词进行"共现"分析,发现"土地复垦"、"生态补偿与保证金"、"植物修复重金属污染"、"地质灾害治理"、"绿色矿山与矿山公园建设"等主题词是该领域的热点研究方向;利用CiteSpace特有的时区图谱分析及突现关键词统计功能,发现中国矿山生态环境修复工作经历了3个研究阶段,内涵不断丰富和发展。多技术融合开展矿山土地复垦与地质灾害治理,矿区水土污染源头控制与治理技术研发、应用集成示范,因地制宜的生态修复技术及绿色矿山、矿山公园建设将是未来矿山生态修复领域的研究热点。

An analysis of the hotspot and frontier of mine eco-environment restoration based on big data visualization of VOSviewer and CiteSpace

Mine ecological environment restoration is an important measure for the construction of ecological civilization, and hence it has attracted more and more attention and interest among geologists. In order to clarify the hot topics of the restoration of the eco-environment in China''s mines in the past 20 years, the frontiers of the historical stage, and the current research progress so as to forecast future research directions, the authors used CNKI as the data source, and employed bibliometrics method and VOSviewer and CiteSpace visual analysis software to quantitatively analyze the relevant documents published in the period of 2000-2018. The results show that, in the past 20 years, the research achievements in the field of mine eco-environment restoration have mainly been published in the form of journals, and the number of documents issued has increased significantly year by year. The key words of "land reclamation", "eco-compensation and deposit", "phytoremediation of heavy metal pollution", "geological disaster management" and "green mine and mine park construction" are the hot research fields through the "co occurrence" analysis of the key words by VOSviewer. Using CiteSpace''s unique time zone map analysis and highlighting key statistics functions, the authors found that China''s mine eco-environment restoration has gone through three phases, and its connotation has been continuously enriched and developed. Multi-technical integration for carrying out mine land reclamation and geological disaster management, water and soil pollution source control and treatment technology research and application integration demonstration, ecological rehabilitation technology adapted to local conditions, and the construction of green mines and mine parks will be the research hotspots in the field of mine rehabilitation in the future.
