摘要
为总结林窗研究进展和前沿热点,根据Web of Science核心数据库获取2002—2022年收录的林窗文献,通过Bibliometrix包以知识图谱展现林窗研究近20年的发展历程.结果表明,2002—2022年Web of Science数据库共收录林窗相关文献2620篇,去除发表年份缺失及重复数据共有2553篇文献,文献发表数量年平均增长率为2.82%.期间出现了许多高产论文作者和高被引论文,期刊影响因子高和被引用量高的文献更易被其他作者引用,直接被引文献主要集中在2002—2008年.林窗文献来源前10名期刊的大类学科以农林科学、工程技术、环境科学与生态学为主,Forest Ecology and Management发表文献数量远高于其他期刊;林窗文献高频关键词主要以growth、dynamics、canopy gaps、regeneration出现频率最高.从关键词出现频率维度分析,以canopy gaps为中心的集群出现频率明显高于其他3个集群.林窗研究的学科目录中Forestry、Environment Sciences&Ecology、Plant Sciences、Remote Sensing等出现频率高,其中遥感技术应用则是近年来该领域的研究热点.
To summarize the progress and current trends in the research on canopy gap,literature related to canopy gap published between 2002 and 2022 were collected from the Web of Science core database.The developments in the research on canopy gap in these 20 years were visually presented using a knowledge graph generated using the Bibliometrics package.A total of 2620 canopy gap-related papers were added to the Web of Science database during this period.Excluding non-applicable and duplicate data resulted in 2553 distinct publications.The average annual growth rate of publications in this area was 2.82%.Notably,several authors produced a substantial number of influential papers,resulting in high citation rates.Studies published in journals with high impact factors were cited more frequently by other authors.Most of the citations could be attributed to literature published between 2002 and 2008.Among the top 10 journals that published papers pertaining to canopy gap,Forest Ecology and Management published a significantly higher number of papers compared to that by other journals,with a focus on agricultural and forestry science,engineering technology,environmental science,and ecology.The most frequently used keywords in the articles pertaining to canopy gaps were growth,dynamics,canopy gaps,and regeneration;these had the highest frequency of occurrence.The cluster centered around canopy gaps exhibited a notably higher frequency of occurrence,surpassing the other three clusters in keyword frequency.In the discipline catalog of canopy gap research,Forest,Environment Sciences&Ecology,Plant Sciences,Remote Sensing,and others were identified as having the highest frequency of occurrence,with recent emphasis on the application of remote sensing technology.
