濒危树种大叶桃花心木的文献计量分析

Bibliometrical analysis of endangered tree species of Swietenia macrophylla

大叶桃花心木作为世界有名的珍贵优质商品用材、城市绿化的高级树种,抗大气污染,且对重金属污染具有较强的修复作用,在2002年被CITES列为濒危Ⅱ类树种。为了更好的了解其国内外研究进展,通过文献计量分析法,从多角度分析国内外大叶桃花心木的研究现状、进展及变化趋势。结果显示:(1)1999年以来国际发文量整体呈上升趋势,国内则在2002-2009年期间较为活跃;(2)以巴西、美国、墨西哥、加拿大为主,美洲国家是大叶桃花心木的主要研究力量;(3)国际热点研究主题以大叶桃花心木资源保护与可持续管理、物种以及基因多样性保护为主。国内研究的主题较多的集中于引种驯化、木材的进出口以及资源开发利用上。

As a world famous advanced timber and greening species,Swietenia macrophylla is resistant to atmospheric pollution and has a strong remediation effect on heavy metal pollution.However,it was listed as endangered class II tree species by CITES in 2002.In view of this,in order to better understand its research progress at home and abroad,this paper analyzed S.macrophylla from multiple perspectives through bibliometric analysis.Research status,progress and trends.The results show that:(1)Since 1999,the volume of international publications has been on the rise as a whole,while domestic publications have been more active during 2002-2009.(2)Brazil,the United States,Mexico and Canada are the main research powers of S.macrophylla in the Americas.(3)The main research topics in the world are conservation and sustainable management of mahogany resources,species and genetic diversity conservation.Domestic research focuses more on introduction and domestication,import and export of timber and resource development and utilization.
