基于文献计量分析的土壤表面电化学发展脉络研究

Bibliometric-based Analysis of Advances in Researches on Soil Surface Electrochemistry

为了全面深入了解全球土壤表面电化学研究进展及发展趋势,本文基于Web of Science核心合集数据库并利用其自带的分析工具和CiteSpace可视化分析软件,从该学科的发文量及时间特征、合作研究空间特征、共现网络特征、共被引图谱和发展特征5个方面对1995—2019年发表的土壤表面电化学文献进行计量分析。结果表明:美国、中国和法国在本领域的发文量居前三,而中介中心性则表明法国、美国和英国位列三甲,我国位于第六位且表现出上升趋势。基于引文的突发性关键词检测表明"阳离子交换(cation exchange)"、"系统(system)"和"络合作用(complexation)"是近十年来的研究热点;文献共被引聚类分析表明生物质炭对土壤改良、黏土层间电荷与罗丹明6G的相互作用、表面电位变化对胶体吸附解吸影响是领域内的研究重点;生物质炭对土壤的改良、带电粒子在双电层中的相互作用机制、土壤黏土矿物表面的水动力特征是本领域研究的前沿问题。

In order to fully understand the progresses and development trends of global soil surface electrochemical research,in this paper,based on web of science core collection database and CiteSpace visual analysis software,soil surface electrochemistry literatures published from 1995 to 2019 were quantitatively analyzed from five aspects:the quantity and time characteristics of the subject,the spatial characteristics of cooperative research,the characteristics of co-occurrence network,the co-citation map and the development characteristics.The results showed that the United States,China and France ranked among the top three in the number of papers published,while the intermediary centrality showed that France,the United States and the United Kingdom were in the top three,and China was in the sixth place with an upward trend.The burst keyword detection based on citations indicated that the"cation exchange","system"and"complexation"have been the research hotspots in recent ten years.The literature co-citation cluster analysis showed that biochar on soil improvement,the interaction between clay interlayer charge and Rhodamine 6G,surface potential change,colloid adsorption and desorption were the research focuses in the field;the improvement of soil by biochar and the interaction mechanism of charged particles in the double electric layer,and the hydrodynamic characteristics of soil clay mineral surface were the frontier issues in this field.
