摘要
为我国土壤重金属研究工作提供参考,系统分析土壤重金属形态的发展动态,以CNKI数据库中收录的2014—2018年“土壤重金属”和“形态”为主题的文献为数据源,借助信息可视化科学计量软件CiteSpace对所采集的数据进行分析,绘制作者合作图谱、机构合作图谱和关键词共现图谱。结果表明:土壤重金属形态研究科研论文数量随着时间变化总体上呈上升趋势,一直是学者关注的热点;作者间存在明显的作者合作群体,主要是以南忠仁和陈寻峰为主的2个群体间作者合作最为密切;中国科学院大学为重点研究机构,但研究机构之间大多都是处于独立研究状态,合作较少;关键词共现图谱显示生物有效性、生物炭和土壤污染为主要研究热点,镉形态和污染特征为最新的研究前沿,是未来几年该领域集中的主要研究方向。
In order to provide references for the research work of heavy metals in soil in China and make a systematical analysis of the developing tendency of heavy metal speciation in soil,the literatures on subject of“soil heavy metal”and“speciation”included in CNKI from 2014 to 2018 were taken as data source,and then they were analyzed with the visualization software CiteSpace.The map of author cooperation network,institution cooperation network and keywords co-occurrence network were made by using the software.Results:The number of research papers on heavy metal speciation in soil showed an upward trend with time and it was always a hotspot for scholars.There were obvious author cooperation groups,the authors of the two groups where Nan Zhongren and Chen Xunfeng were located had the most close cooperation.University of Chinese Academy of Sciences was the key research institution and most of the research institutions were in an independent research state with little cooperation.The map of keywords co-occurrence network showed that bioavailability,biochar and soil pollution were the main research hotspots,cadmium speciations and pollution characteristics were the latest research frontiers,which were the main research directions in this field in the next few years.
