基于CiteSpace的有关绵羊繁殖周期研究知识图谱分析

CiteSpace-based knowledge mapping analysis of international researches on sheep reproductive cycle

为全面分析绵羊繁殖周期的研究现状及变化趋势,本文采用文献计量学统计方法,分析Web of Science数据库中1936—2022年有关绵羊繁殖周期研究的4732篇文献,主要内容包括:被引文献、机构、作者、关键词、研究内容等,并使用CiteSpace 6.1 R6软件绘制网络知识图谱。结果:近年来国外绵羊繁殖周期相关发文量略有增长,我国对其关注度不断提高,相关领域科研支持大幅度提升;绵羊繁殖周期相关成果被引频次逐年增加,且与发文量成正比,各国之间有关科研领域交流正在不断增强;美国、英国、澳大利亚等国家对绵羊繁殖周期研究的成果较多,我国在该领域投入仍存在很大差距;针对主要机构及作者进行分析表明,机构、作者间的关联线比较密集;高频被引文献分析发现,绵羊繁殖周期的研究与营养需求和生理调节二者之间的关系密切;对关键词检索进行分析表明,与绵羊繁殖周期研究相关的高频热点词汇共有25个,在不同时间段,有一部分词汇会重复出现。通过以上分析,有利于加深研究前沿及成果的相互借鉴,提高绵羊养殖的效益产出,为提高我国绵羊繁殖性能提供参考和理论依据。

In order to comprehensively analyze the research status on and the changing trend of sheep reproductive cycle,this paper adopt⁃ed the bibliometric statistical method,and analyzed a total of 4732 articles about sheep reproductive cycle published from 1936 to 2022 in the Web of Science database.The main contents of the analysis included cited articles,institutions,authors,keywords,research contents,etc.CiteSpace 6.1 R6 software was used to draw a network knowledge map.The results showed that,in recent years,the number of papers related to the international sheep reproductive cycle has increased slightly,and our country has paid more attention to this field of research.The results related to sheep reproductive cycle have been cited more and more every year,which is directly proportional to the amount of pub⁃lications.The exchange in scientific research between different countries has been increasing.There are many research results on sheep repro⁃ductive cycle in America,Britain,Australia and other countries,and our country is quite lag behind in this field of research,although in⁃vestment here has been increasing.It is found in the high frequency citation analysis that researches on sheep reproductive cycle are closely related to the nutritional requirements and physiological regulation of sheep.There are 25 high-frequency hot words related to the study of sheep reproductive cycle,and some of them have repeated in different periods of time.The present analysis is helpful in promoting the frontier of research on sheep reproductive cycle and mutual reference to research results so as to raise the benefit of sheep breeding output,to provide theoretical support and technical reference for our effort in enhancing sheep reproductive performance.
