世界家畜反刍行为研究的知识图谱分析

Literature analysis of knowledge map on livestock’s ruminantbehavior in world

为了解世界家畜反刍行为领域的研究现状,文章基于关键词共现分析、文献共引分析、聚类分析等计量学方法,借助信息可视化软件CiteSpaceⅢ,绘制1965—2017年间世界家畜反刍行为研究领域的科技文献可视化知识图谱。结果表明：世界家畜反刍行为相关研究从1991年开始突发性增长,发文量逐年增加,主要研究国家有巴西和美国。由突发被引文献和热点词汇分析可以了解到,世界家畜反刍行为研究热点为动物行为监控及其与生产性能相关的研究。我国家畜反刍行为研究的发文数量较高,热点内容与世界发展趋势类似,但受反刍行为信息收集方法的限制较大。

In order to understand the research status of livestock＇s ruminant behavior field in world,a visualized knowledge map of scientific literatures in 1965—2017 on livestock＇s ruminant behavior field in world was drawn,based on several metrological methods containing keyword co-occurrence analysis,literature co-citation analysis and cluster analysis,and information visualization software Cite Space Ⅲ was used.The results showed that the research of world ruminant behavior began to increase suddenly from 1991,and the amount of publication grew year by year,with the main research countries being Brazil and United States.According to the analysis of sudden citation literatures and hot words,research hot spots of world ruminant behavior were the field of animal behavior monitoring,and its correlation study with production performance.There was an high amount of literatures on livestock＇sruminant behavior in China,and the hot contents in China were in accordance with those in world,but it was limited by the method of information collection of ruminant behavior.
