基于 CiteSpace 分析国内树洞研究文献及发展趋势

Analysis on the Research Literature and Development Trend of Tree Hole in China Based on CiteSpace

摘要:

树洞是一种常见的树木腐朽现象，为了解树洞的研究现状和发展趋势，借助CiteSpace软件，对中国知网、万方、维普三大国内数据库截至2021年7月收录的期刊文献进行分析，并形成可视化图。结果发现：国内树洞研究在1957年进入起步阶段，21世纪后发展速度开始加快，发文量整体呈上升趋势，研究内容集中在树洞修补、树洞养护管理、树洞生物、巢箱设计、树洞周边愈伤木和森林空心树6个方面。同时，在此基础上依据关键词突现图分析发展趋势，结果显示：对树洞的研究在初期以森林生态系统为主，后期逐渐倾向于对树木的保护复壮和生态系统的维护，研究范围逐渐扩大。

Abstract:

Tree hole is a common phenomenon of tree decay.In this study, the periodical literatures collected by CNKI,Wanfang and Weipu up to July 2021 were analyzed and visualized based on the CiteSpace software, so as to analyze the research status and development trend of tree holes in China. It was concluded that the tree hole researches entered the initial stage in 1957,and developed rapidly in the 21st century. The number of published articles were rising steadily. The research contents focused on six aspects: tree hole repair, tree hole maintenance and management, tree hole biology, nest box design, callus around tree hole and forest hollow tree. Subsequently, the development trend of tree holes was analyzed according to key words emergent graph. It was known that the research scope of tree holes has gradually expanded, from forest ecosystem in the initial stage, to the protection and rejuvenation of trees, the maintenance of ecosystem, and so on.
