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3 602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1 528篇样本文献,其中包括中文文献142篇和英文文献1 386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 3 602 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 1 528 sample literatures were selected as the date source of this study,including 142 Chinese literatures and 1 386 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.
