摘要
[目的]为了解国内氮沉降对土壤微生物研究的方向和热点。[方法]选取2005-2019年CNKI数据库中文核心期刊、硕博论文和Web of Science(WoS)核心合集收录的相关文献为数据样本,基于文献计量学的可视化分析,以知识图谱为研究载体,通过Excel、CiteSpace等分析软件为工具,对所选数据进行关键词的聚类分析,同时绘制各类相关数据分析以及图谱。[结果]从发表年份来看,我国氮沉降对土壤微生物研究较晚,始于2005年,一直到2015年左右才达到峰值状态,核心期刊近些年保持平稳状态,硕博论文从2016年发文达到峰值之后,逐渐回落。SCI论文除2009、2012、2016年有轻微下降外,从总体上看保持上升趋势。从关键词来看,在核心期刊和硕博论文中,土壤微生物与土壤呼吸有紧密联系。“碳”(carbon)、“多样性”(diversity)和“生物”(bioma)一直是SCI论文中氮沉降对土壤微生物的研究热点。从研究作者来看,我国氮沉降对土壤微生物研究领域的核心作者形成了以卢明珠、方华军、曹子铖和徐梦等人、商帅帅、王春梅和李俊青等人、向元彬、周世兴和黄从德等人为联系的作者合作关系图谱。发表SCI论文最多的作者是Donald R Zak,Stefan Scheu和Stefan Scheu发文量紧随其后。从研究机构来看,中国科学院大学在氮沉降对土壤微生物领域研究发文量最多,从硕博论文来看,东北师范大学最多。SCI论文发文量排前2位的主要是Chinese Acad SCI和Chinese Acad SCI University,说明中国的科研机构就氮沉降对土壤微生物研究较广泛。[结论]近些年的研究热点与未来发展有可能是生物多样性、荒漠草原、常绿阔叶林和磷脂脂肪酸等研究。SCI论文中显示出的未来研究热点可能是细菌群落和有机碳的研究。
[Objective]To understand domestic nitrogen deposition on soil microbial research direction and hotspot.[Method]Database of CNKI from 2005 to 2019 Chinese core journals,Thurber papers and Web of SCIence(WoS)core collection of relevant literature were selected as the data samples.Based on the visual analysis of literature metrology,we used knowledge map as the research carrier.Keywords clustering analysis of the selected data was selected through the analysis software tools such as Excel,CiteSpace.At the same time,all kinds of related data analysis and mapping were carried out.[Result]From the aspect of year of publication,the research of nitrogen deposition on soil microorganisms in China was relatively late,which started in 2005 and did not reach its peak until 2015.The core journals maintained a stable state in recent years,and the master and doctoral papers gradually declined after reaching their peak in 2016.Except for a slight decline in 2009,2012 and 2016,SCI papers generally maintain an upward trend.From the aspect of key words,soil microorganisms are closely related to soil respiration in core journals and master and Doctoral dissertations.“Carbon”,“diversity”and“bioma”have been the research sites of soil microorganisms by nitrogen deposition in SCI papers.From the aspect of study author,the core authors of the research field of nitrogen deposition on soil microorganisms in China formed a cooperative relationship map of authors with Lu Mingzhu,Fang Huajun,Cao Zicheng,Xu Meng,Shang Shuaishuai,Wang Chunmei and Li Junqing,Xiang Yuanbin,Zhou Shixing and Huang Congde as human contacts.Donald R Zak is the author of the most SCI papers,followed by Stefan Scheu and Stefan Scheu.From the aspect of research institutions,the University of Chinese Academy of Sciences has published the most papers on nitrogen deposition in the field of soil microorganisms,and from the perspective of Master and doctoral theses,northeast Normal University has the most papers.Chinese Acad SCI and Chinese Acad SCI University rank the top two in the number of SCI papers published,indicating that Chinese scientific research institutions have conducted extensive researches on soil microorganisms regarding nitrogen deposition.[Conclusion]Recent research hotspots and future development may be biodiversity,desert steppe,evergreen broad-leaved forest and phospholipid fatty acids.The future research hotspot shown in SCI papers may be the research of bacterial community and organic carbon.
