摘 要:森林更新是维持森林群落结构稳定的重要生态学过程。幼苗更新是森林更新方式之一,也是林木生长过程中极为重要的阶段,是森林群落演替的关键环节,了解木本植物幼苗更新研究进展有助于理解森林群落的更新与演替机制。本文对2012—2021年Web of Science核心合集数据库3598篇文献进行了可视化分析。通过构建科学知识图谱,梳理出森林幼苗更新研究文献的变化、作者与机构的合作关系以及热点关键词。研究结果从收录论文的角度,定量、客观地描述了2012—2021年森林幼苗更新的研究状况及研究热点,直观地反映森林幼苗更新研究中网络、结构、交叉等知识群之间的复杂关系,阐明了森林幼苗研究的现状和发展趋势,为促进木本植物幼苗更新深入研究及相关领域学者凝练研究动向和科学问题等提供参考信息。Forest renewal is an important ecological process to maintain the stability of forest community structure. Seedlingregeneration is one of the ways of forest renewal, and also an extremely important stage in the forest growth process.It is the key link of forest community succession. Understanding the research progress of woody plant seedlingregeneration is helpful to understand the mechanism of forest community renewal and succession. In this paper,3598 articles in the Web of Science core collection database from 2012 to 2021 were visually analyzed. Byconstructing scientific knowledge map, tease out the change of the forest seedling update research literature, theauthor and institutions and hot keywords results from the perspective of included paper, quantitative, objective andscientifically described the 2012—2021 forest seedlings update research status and research hotspot, intuitivelyreflect the forest seedlings update research network, structure, cross and the complex relationship betweenknowledge group, illustrates the present situation and development trend of forest seedlings, to promote woody plantseedlings update further research, and related scholars concise research trend and scientific problems to providereference information.
