基于文献计量的国内外人工林土壤地力研究

Study on Soil Fertility of Plantation at Home and Abroad Based on Bibliometrics

为了解国内外人工林土壤地力的研究进展和发展趋势,采用文献计量学方法,以中国知网(CNKI)和Web of Science核心合集数据库相关文献为数据源,利用VOSviewer、HistCite等工具,从国家、机构、作者、研究热点方面对2021年之前的有关文献进行了计量分析。结果表明:国内外该领域年发文量呈逐渐增长趋势,国际上发文量前3位的国家是中国、美国和巴西;中国最先在该领域进行研究且与国际的合作交流较多,文献总被引频次位居前列;国内该领域发文机构主要为涉林高校及中国科学院下属研究所,国际上美国俄亥俄州立大学发表的文献质量明显突出,引用频次较高;现阶段国内外在该领域的研究主要围绕土壤微生物群落组成、土壤养分含量以及与土壤地力维持的关系,但多处在定量描述阶段,很少涉及微生物功能代谢与人工林下有机物质周转以及对土壤地力维持的影响机制,研究深度亟待提升。总之,国内外同行合作交流、学科间交叉融合以及新生研究力量的补充是未来有效提升该研究领域的关键所在。

Based on the related literatures of CNKI and Web of Science Core Collection Database,the research status and future development direction of plantation soil fertility at home and abroad were investigated by using bibliometrics method in order to provide reference basis for subsequent scholars to study in this field.VOSviewer visualization software,HistCite citation map analysis software were performed for the quantitative analyses of countries,research institutions,authors,hot spots that involved in this area.All the relevant literatures used were published before 2021.The annual volume of literature published in this field is increasing gradually,and the top three countries are China,the United States and Brazil.China is the first to conduct research in this field,and has more cooperation and exchanges with the international community,and the total citation frequency of literature ranks in the forefront.Domestic research institutions are mainly forest-related universities and institutes affiliated to Chinese Academy of Sciences.Internationally,the literatures issued by Ohio State University were outstanding quality and frequently citation.At present,the research in this field at home and abroad mainly focuses on the compositions of soil microbial community,soil nutrient contents and the relationship between soil fertility maintenance and plantation,but the related research is mostly in the quantitative description stage,and does not involve the functional metabolism of microbial community,the underline mechanism in the turnover of organic materials in soil fertility maintenance.This study clearly shows the current research hotspots and future development trends in this field,and provides reference values for relevant personnel.In brief,the cooperation and exchange between domestic and foreign peers,interdisciplinary integration and the supplement of new research strength may be the key to effectively promote this research field in the future.
