基于文献计量的国际黑土研究态势分析

Analysis of International Black Soil Research Situation Based on Bibliometrics

[目的/意义]黑土是全球最珍贵的土壤资源,通过探讨国际黑土领域的研究现状和进展,促进我国黑土领域的深入研究和黑土地保护。[方法/过程]该文基于Web of Science数据库核心合集,对黑土领域相关文献进行整理分析,利用文献计量学方法和知识图谱可视化方法,从年度发文趋势、主要国家发文情况、主要机构发文情况、高被引论文情况和研究主题分布五个方面,对全球黑土领域论文的整体状况进行定量统计和定性分析,总结国际黑土领域相关研究进展。[结果/结论]研究结论显示,全球黑土领域发文总体呈快速增长趋势,中国是该领域发文最多的国家,俄罗斯和美国紧随其后。从论文影响力看,中国、美国和加拿大的总被引频次位居前三,篇均被引频次排名前三的国家分别是加拿大、美国和澳大利亚。发文机构以中国和俄罗斯的科研机构为首,中国科学院和俄罗斯科学院发文量最高。国际黑土研究热点主要集中在黑土流失现状、黑土地农作物种植、黑土地结构及重金属污染、土壤有机质和土壤微生物群落及其多样性。各国研究主题各有侧重。

[Objective/Significance] In order to study the international research status and progress in the field of black soil,and to promote further research and protection in the black soil field in China,this paper sorts out and analyzes the relevant literature in the black soil field from the core collection of Web of Science databases.[Methods/Progress] By using bibliometrics methods and knowledge graph visualization method,this paper summarizes the relevant research progress in the international black soil field respectively from the aspects of the annual publishing trend,publishing situation of major countries and major institutions,the situation of highly cited papers and the distribution of research topics.[Results/Conclusions] The conclusion shows that the number of papers published in the field of black soil in the world has been increasing exponentially in recent years.China is the country with the largest number of papers published in this field,followed by Russia and the United States.In terms of research impact,China,the United States and Canada are among the top three in terms of total citation frequency;Canadan,the United States and Australia are among the top three in terms of the average citation frequency.Scientific research institutions from China and Russia are the leading ones,with the Chinese Academy of Sciences and the Russian Academy of Sciences having the highest number of publications.Research hotspots mainly focus on the status of black soil loss,crop planting on black soil,black soil structure and heavy metal pollution,soil organic matter and soil microbial community and its diversity.Research priorities vary from country to country.
