杉木研究科技文献计量分析

Bibliometrical analysis on scientific literatures in Cunninghamia lanceolata research

杉木是中国南方主要的造林树种,在中国南方的林业生产和森林生态中都具有十分重要的地位和作用。对杉木研究文献进行计量学统计分析有助于科学认识杉木研究发展动态,追踪研究重点和热点。以Web of ScienceTM核心合集和中国基础知识设施工程(CNKI)文献数据库中的期刊全文数据库为数据源,利用Bibexcel、Ucinet和NetD raw文献计量工具对1951-2013年国内外杉木研究文献的数量年动态、主要研究国家或地区及其文章影响力、涉及学科与研究层次,主要研究机构与研究人员、关键词共现网络进行了计量分析。结果表明,杉木研究主要集中在中国,且文章的被引频次和h-指数最高;福建省在科研投入、科研机构、科研人员、科研成果方面具有明显优势,论文的产出省份与杉木主要分布省份高度相关;关键词共现网络显示近5 a来的研究热点为"冰雪灾害"、"凋落物"、"土壤肥力"、"混交林"、"材质"、"遗传育种"、"碳固定模型";研究主要集中在福建省、广西省、湖南省、浙江省、江西省5个省份。

Cunninghamia lanceolata （ Chinese fir ） is main afforestation species in south of China , and of great significance to forestry and forest ecosystem conservation .Bibliometrical analysis of Chinese fir research literature would contribute to the scientific understanding of the dynamic of Chinese fir research , and tracking research focus .In this paper , Web of Science and CNKI databases were adopted, SATI, Ucinet and NetDraw were applied to conduct bibliometrical analysis on the number of literature annual dynamic, main countries and areas characteristic indexes , lead authors and institutes , online co-occurrence graph of keywords .The results showed that China is the leader of Chinese fir research and its cited frequency together with h -index were all significantly higher than other countries .Compared with other provinces , Fujian Province shows obvious advantage than others no matter in research capacity and research achievements .Besides, the research output-provinces are highly correlated with Chinese fir mainly distribution-provinces .The network co-occurrence graph of keywords reveal that the recently hot spots are ice -snow damage , litter, soil fertility, mixed forest, wood quality, genetics and breeding, model of carbon fixation.Fujian, Guangxi, Hunan, Zhejiang, Jiangxi are the mainly study samples .
