奶牛场废弃物研究态势的全球文献计量分析

Bibliometric analysis of world literature on trend in research on animal waste on dairy farms

为了全面了解有关奶牛粪便研究的发展状况及该研究领域的历史动态,运用CitespaceⅢ信息可视化软件对1925-2016年内Web of Science核心合集系列数据库收录的2 395条有关奶牛粪便研究领域的共引文献、研究机构、高频热点词汇进行了分析,并绘制了关于该领域的科技文献知识图谱。结果表明:国际上有关奶牛粪便研究的关注在不断提高,美国、加拿大、瑞典、荷兰等国家在该研究方向处于领先水平;同时该领域向着系统性、多学科的方向发展,说明国际间以及机构合作有利于加强并推动奶牛养殖业与奶牛粪便研究的发展。

In order to grasp the development of research on cow manure and the history of research in this field, the information visualization software Citespace Ⅲ was employed to analyze 2395 co-citated literature items, institutions co-appearing keywords in the 1925-2016 series of databases of Web of Science research on dairy cow waste, and a knowledge map of the sci-tech literature in this field. The results showed that the international concern about research on cow waste is increasing, with the United States, Canada, Sweden and the Netherlands are at the leading level in the research direction. At the same time, the research is developing in a systematic and multidisciplinary manner, which indicates that international and inter-institutional cooperation would be conducive to promoting research on the development of dairy farming and on cow waste.
