基于“中国知网”文献计量的近20年国内小反刍兽疫研究分析

Analysis on Peste Des Petits Ruminants Researches in the Past 20 Years in China Based on Bibliometrics of"CNKI"

为了解国内小反刍兽疫领域的最新研究热点和发展趋势,借助“中国知网”数据库,基于CiteSpace可视化软件,对2000—2021年发表的小反刍兽疫相关研究文献的作者、来源期刊、研究内容及关注热点等,从发文量、文献被引频次、文献总下载量等方面,分析来源期刊及高被引文献,构建研究者合作关系,重点分析国内不同时间段的关键词共现网络图谱和时间线图谱。结果显示:该领域的年度发文量呈阶段性增长态势,且国内已形成相对稳定的科研团体;《中国动物检疫》期刊的均篇被引频次、被引总频次和篇均下载量均位于首位,尤其是2007年王志亮团队发表的研究论文备受关注;诊断、防控、治疗、临床症状、流行病学、免疫、疫苗等关键词出现频次较高,从38次到117次不等,各关键词间连接线多而紧密,但以诊断、防控、治疗出现频次最高;2000—2006年文献数量少,研究内容分散,关键词出现频率低,相互联系较少;2007—2012年文献数量开始增多,但热度不高,范围较单一;2013—2021年文献数量持续增高,研究范围拓宽,以基因表达、免疫检测、治疗诊断等为主。结果表明:国内PPR研究网络虽然形成稍晚,但近期发展快速,研究团体趋于稳定,研究范围更为广泛,其中基因表达、免疫检测、治疗诊断成为最新研究热点。本研究为全面了解国内小反刍兽疫研究状况,研判前沿热点,促进研究合作提供了参考。

In order to investigate the latest research hotspots and development trends in the field of peste des petits ruminants(PPR)in China,with the help of the database of“CNKI” and based on CiteSpace visualization software,the authors,source journals,contents and hotspots of researches and other factors of relevant literatures concerning PPR published from 2000 to 2021 were analyzed,especially the source journals and the highly cited literatures,from the aspects of the number of papers published,the frequency of citations and the total number of downloads,a cooperative relationship between researchers was built,the key word co-occurrence network map and timeline map in different periods were analyzed as a priority. The results showed that the annual publication volume in this field had grown in stages,and a relatively stable scientific research group had been formed in China;taking the journal of China Animal Health Inspection as an example,its average citation frequency,total citation frequency and average download volume ranked first,especially the papers published by Wang Zhiliang’s team in 2007;key words such as“diagnosis”“prevention and control”“treatment”“clinical symptom”“epidemiology”“immunization”and“vaccine”appeared frequently,ranging from 38 to 117 times,and linked with each other through several routes,but“diagnosis”“prevention and control”and“treatment” appeared with highest frequency;the number of literatures published from 2000 to 2006 were lower with scattered contents,key words were used with low frequency and little interaction;that of those from 2007 to 2012 began to increase with low concern and single scope;and that of those from 2013 to 2021 continued to increase with broadened scope and a priority of gene expression,immune detection,and therapeutic diagnosis. In conclusion,domestic PPR research network was formed later,but it had been developed rapidly in recent years,a team working for relevant research trended to be regular with extensive scope,especially the latest hotspots including gene expression,immune detection,therapeutic and diagnosis. A reference was thereby provided for comprehensively identifying the research status of PPR in China,studying and determining the frontier and hotspots and promoting cooperation for research.
