矿山复垦研究热点与发展趋势——基于Citespace可视化分析

Research hotspots and development trend of mine reclamation based on visualization analysis of CiteSpace

为形象客观地呈现近21年来中国矿山复垦工作的研究热点及发展趋势,以中国知网(CNKI)为数据源,借助CNKI、Excel和Citespace软件,采用文献计量学方法,对CNKI数据库以矿山复垦为主题的文献数据进行研究。从作者及机构合作分析、关键词共现、聚类分析和突变词探测等方面对国内矿山复垦的科研力量、研究热点、发展趋势和研究前沿等进行分析。结果显示,北京市和山西省的科研群体在该领域发文量较高;研究热点包括土地复垦、复垦土壤、生态恢复及重建、适宜性评价及重金属等;其发展可划分为3个阶段,即起步阶段(2000—2006)、发展阶段(2007—2013)和深化阶段(2014—2020)。

In order to comprehensively present the research hotspots and development trend of mine reclamation in China in recent 21 years.Taking CNKI as the data source,using CNKI,Excel and CiteSpace software,using bibliometric method,analyze the literature data on the subject of mine reclamation in CNKI database.Analyzes the scientific research strength,research hotspots,development trends and research frontiers of mine reclamation in China from the aspects of cooperation analysis between authors or institutions,keyword co-occurrence analysis,cluster analysis and emergent word detection.The results show that the scientific research groups in Beijing and Shanxi Province published more papers in this field;land reclamation,reclaimed soil,ecological restoration and reconstruction,suitability evaluation and heavy metals are the research hotspots;its development could be divided into three stages:initial stage(2000—2006),development stage(2007—2013)and in-depth development stage(2014—2020).
