基于Cite Space的红锥发展现状分析

Analysis on the development status of Castanopsis hystrix based on Cite Space

以CNKI数据库中1985-2021年的532篇期刊论文作为数据源,利用Cite Space可视化文献分析工具,对红锥研究领域的研究活力、发文作者、机构分布、热点和趋势进行分析,并绘制出相关知识图谱,以此来探讨红锥研究领域的发展现状以及相关研究热点。结果表明:(1)红锥已受到学者们的广泛关注,研究内容开始多样化,该领域研究充满活力;(2)发文作者大多来自于中国林业科学研究院热带林业实验中心、广西林业科学研究院、广西大学这3家机构,机构内部之间合作关系极为密切,不同机构之间也存在密切合作;(3)从热点和趋势来看,红锥研究领域热点关键词主要有马尾松、杉木、西南桦、桉树、人工林、混交林、南亚热带、种源。研究趋势主要集中在优质种源筛选、遗传变异、新育苗技术、混交树种配置、大径材培育、固碳、生态服务功能、土壤微生物及微量元素等方向。同时根据红锥研究现状,给出了关于红锥研究领域未来发展的建议。

Based on 532 journal papers in CNKI database from 1985 to 2021,Cite Space visual literature analysis tool was applied to analyze the research field in"Castanopsis hystrix",including research vitality,distribution of authors and institutions,hotspots and trends.Then we draw the relevant knowledge graph to discuss the research field development status and related research hot spots.The results show that:(1)C.hystrix has been widely concerned by scholars,and the research content has been diversified,the research in this field is full of vitality;(2)Most authors from the Tropical Forestry Experimental Center of CAF,Guangxi Academy of Forestry and Guangxi University.The cooperation between the institutions is very close,and there is also close cooperation between different institutions;(3)In terms of hotspots and trends,the hotspot keywords in C.hystrix research field mainly include Pinus massoniana,Cunninghamia lanceolata,Betula alnoides,Eucalyptus stands,plantation,mixed forest,South Subtropical and provenance.Research trends mainly focused on the selection of high-quality provenance,genetic variation,new seedling technology,mixed forest configuration,large-diameter timber cultivation,carbon sequestration,ecological service function,soil microorganisms and trace elements.At the same time,according to the current status of C.hystrix research,give some suggestions on the future development.
