基于知识图谱的土壤线虫研究现状及发展趋势分析OA

In order to reveal the research progress and trends in the field of soil nematodes,this study employed the CiteSpace bibliometric method to conduct a visual analysis of soil nematode research literature from 2002 to 2021 in the CNKI core database(459 articles)and the Web of Science core collection(5822 articles).The results showed that:(1)research output had shown sustained growth.International research entered a period of rapid expansion from 2009 to 2012,with an average annual increase of 153 publications.From 2013 to 2020,it transitioned into a phase of stable growth,averaging 513.13 publications per year.The top three high-output international institutions were the University of Florida(Univ Florida),Ghent University(Univ Ghent),and the Agricultural Research Service(ARS).The top three high-output domestic institutions were the Chinese Academy of Sciences,Nanjing Agricultural University,and China Agricultural University.(2)Research hotspots focused on core areas such as the structural characteristics of soil nematode communities,the dynamics of trophic functional groups,the diversity of ecosystem functions,biological control techniques,the response mechanism of maturity index(MI),the effects of organic fertilizer application,and the interaction between microorganisms and genes.(3)International leading research teams were represented by CAMPOS-HERRERA R and VAN DER PUTTEN W H,while domestic key research clusters were represented by the Li Huixin-Hu Feng-Liu Manqiang team and the Liu Qizhi-Li Heqin-Wang Xuexia team.The study indicates that soil nematode research has formed a multi-dimensional research system,but it is necessary to strengthen collaborative innovation among domestic and international research teams,especially in emerging cross-disciplinary fields such as functional genomics and ecological network analysis.
