基于CiteSpace和VOSviewer的树冠火研究热点与趋势可视化分析

Visualization Analysis of Research Hotspots and Trends of Crown Firebased on CiteSpace and VOSviewer

通过检索中国知网和Wed of Science数据库中2013年1月至2023年12月文献,共检索出树冠火领域的相关文献共3602篇。借助CiteSpace 6.1.R6和VOSviewer1.6.20软件进行设定年份阈值、语言种类、文献类型等手段,再通过人工筛选,共采用1528篇样本文献,其中包括中文文献142篇和英文文献1386篇作为本次研究的数据源。结果表明:英文文献作者之间联系较为紧密,而且研究内容覆盖面积广,在国际水平上占据主导地位,有较强学术影响力。然而中文作者研究程度较为浅显,而且年发文量呈现逐年递减趋势,国际影响力低。当前树冠火在国内研究处于萌芽阶段,与国际化水平存在较大差距,因此该研究领域空白较多,迫切需要进行深入研究,以期为树冠火预防和扑救提供理论依据。

By searching the literatures from January 2013 to December 2023 in CNKI and Wed of Science database,a total of 3602 literatures about crown fire were retrieved.By using CiteSpace 6.1.R6 and VOSviewer1.6.20 software,the year threshold,language type and literature type were set.After manual screening,a total of 1528 sample literatures were selected as the date source of this study,including 142 Chinese literatures and 1386 English literatures.The results showed that the authors of English literature are closely related,and the research content covers a wide area,which occupies a dominant position in the international level and has a strong academic influence.However,the research degree of Chinese authors is relatively shallow,and the annual number of published papers shows a trend of decreasing year by year,and the international influence is low.At present,the research on crown fire in China is in the embryonic stage,and there is a great difference between it and the international level.Therefore,there are many gaps in this research field,and in-depth research is urgently needed to provide theoretical basis for the prevention and suppression of crown fire.
