摘要
分析我国柑橘研究领域近10 a(年)的热点与前沿主题,便于相关研究者了解本领域的研究现状。以Web of Science数据库中2010—2019年我国柑橘研究相关学术论文为研究对象,运用文献计量可视化软件CiteSpace对其进行作者、机构、主题词共现和文献共被引分析。检索范围内发表的我国柑橘研究论文共3 168篇,发文数量整体呈现逐年增长的趋势,受到多学科、多领域的广泛关注。研究机构以华中农业大学发文量最多,其次是西南大学、浙江大学。已经形成了以邓秀新和吴强盛等为核心的学术团队群。近10 a研究热点有组学研究、抗氧化、系统发育分析、黄龙病、丛枝菌根、柑橘精油、果实品质等。2016—2019年高突现主题词预示着当前研究热点指向柑橘有效成分及其药用价值研究。研究前沿主题涵盖柑橘黄龙病、柑橘系统发育分析、柑橘有效成分及其功能研究、丛枝菌根、柑橘果实品质研究等多个方面。其中与柑橘系统发育分析相关的文献影响力最强。近年来我国科研人员对柑橘从多学科、多领域开展了广泛、深入的研究。从研究内容来看,基础理论研究较多,与柑橘产业结合紧密的研究相对较少,有待进一步加强基础研究成果向应用领域的延伸。
Based on the 2010—2019 database from Web of Science,we analyzed the hotspots and frontiers of Citrus research in China,which could help relevant researchers to understand the current situation in this field.Using"citrus","trifoliate orange"or"kumquat"as topic,a preliminary search was done on Web of Science,which resulted in the records of literature data published in China between2010 and 2019.By using the analysis and retrieval function of WOS and Excel,the literature data were analyzed in terms of annual and literature subject categories.Based on the bibliometric analysis software CiteSpace,author,institution,co-word and co-citation were analyzed,respectively,so as to obtain the statistical data and the visualized network of Citrus research.Accordingly,research hotspots,intellectual structure and frontier topics were analyzed.A total of 3168 citrus-related articles were retrieved from WOS database.The number of articles related to Citrus research increased steadily,and the contents involved various subjects and fields.Plant science was the largest publishing subject category,accounting for 18.88%of the total published articles,followed by food science technology,biology,horticulture,chemistry,microbiology,agriculture,pharmacology,entomology,nutriology and so on.The top 3 most productive institutes were Huazhong Agricultural University,Southwest University and Zhejiang University,which are located in Hubei,Chongqing and Zhejiang,respectively,in accordance with the distribution of citrus production,suggesting that the research institutes of citrus in China were closely related to the geographic distribution of citrus cultivation.Academic teams with Deng Xiuxin and Wu Qiangsheng as the core have formed.The co-word analysis showed that the hotspots of citrus research in the past decade included omics,antioxidant system,phylogenetic analysis,huanglongbing,arbuscular mycorrhiza,citrus essential oil,fruit quality,etc.In recent years,the omics studies have been widely used in various fields of citrus research.From 2010 to 2015,the high-burst terms,such as"mycorrhizal colonization","arbuscular mycorrhizal","host plants"and so on,indicated that the research focus of this stage was arbuscular mycorrhizal.From 2016 to 2019,the high-burst terms,such as"principal component analysis""oxidative stress""NF kappa B"and so on,indicated that the current hotspots of citrus research were active ingredient and medicinal value of citrus.The timeline of co-citation clusters in citrus researches showed that the hotspots and their duration varied with time.The co-citation analyses showed that the frontiers in research included huanglongbing,phylogenetic analysis,active ingredient extraction and functions analysis,arbuscular mycorrhiza,citrus fruit quality and so on.The above research topics have a strong sustainability.Among them,the literatures related to phylogenetic analysis of citrus possess the strongest influence.In the process of knowledge evolution of citrus research,"the draft genome of sweet orange(Citrus sinensis)"from Xu Qiang was the most important work in this field.The highly cited and central literatures in citrus research mainly focus on the basic research fields such as omics and molecular biology,and the applied research is less.In the past decade,Chinese scholars have carried out extensive and in-depth research on citrus from multidisciplinary fields.The main research forces were from universities,followed by research institutes.Most of the researches were theoretical studies and few were closely related to the citrus industry.In future,more efforts should be made to strengthen the conversion of basic research into practical application.
