基于CiteSpace的知识图谱分析我国澳洲坚果研究进展

Research Progress of Macadamia Nuts in China Based on CiteSpace Knowledge Graph

该文运用CiteSpace软件对1992—2022年CNKI核心期刊收录的有关澳洲坚果研究的312篇学术论文进行可视化分析。结果显示,学者们不仅注重在学术方向的交叉融合,也已构建了较好的科研团队。云南省热带作物科学研究所长期关注澳洲坚果的研究,是发文量最多的研究机构。关键词“澳洲坚果”首次出现于1992年,且出现频次为200次,明显高于其他关键词。进一步分析同时含有“澳洲坚果”关键词,且被引用总次数大于等于40次的论文研究内容,在澳洲坚果光合作用、遗传育种、果仁营养成分、低温和水分胁迫以及内源激素等方面的研究,受到论文作者们更多的关注和重视。关键词突现图谱显示,良种选育和繁育、果实品质及果仁功能性成分开发一直是学者们重视的研究内容。

Using CiteSpace software,this paper made a visual analysis of 312 core scientific papers collected by CNKI from 1992 to 2022.The results showed that the authors of the papers not only focused on the cross-integration in academic directions,but also built a good scientific research team.Yunnan Institute of Tropical Crops has long paid attention to the research of Macadamianuts,and it is the research institution with the most publications.The keyword"Macadamia nut"first appeared in 1992,and its occurrence frequency was 200 times,which was significantly higher than that of other keywords.Further analysis of research papers which contain the keywords"Macadamia nut"and have been cited more than 40 times shows that research in the aspects of Macadamia nut photosynthesis,genetics and breeding,kernel nutrition,low temperature and water stress,and endogenous hormones has drawn more attention from the authors.The keyword emergence diagram shows that the selection and breeding of improved varieties,the development of fruit quality and functional components of nuts have always been the focus of research for researchers.
