近三十年我国桉树专题文献计量分析

为了解我国桉树相关行业的发展动态,本文以中国知网数据库(www.cnki.net)的文献为数据源,以文献计量学方法,对我国1987—2016年共30 a的桉树专题相关文献进行阶段性(以10 a为界)统计,从文献数量、学科分布、研究层次、文献作者、发文机构、资助基金、文献来源和关键词等8个方面进行了分析.结果表明:随着年份增长,桉树专题文献数量总体呈现上升趋势,1987—1996、1997—2006及2007—2016年的文献数量分别为965、2115及4631篇,以第3阶段(2007—2016年)增幅最大.30 a间3个阶段桉树研究的学科领域均以林业学科最多,所占比例为70%左右,研究层次均以工程技术(自科)和基础与应用基础研究(自科)为主.不同阶段文献作者的最高发文数量分别为11、30和75篇,发文机构均主要集中在广东、广西、云南、湖南、福建等地.3个阶段的文献主要以国家科技攻关计划和国家自然科学基金资助为主,文献来源主要出自期刊,整个30 a间,均以《桉树科技》所刊登的文章数量为最多,是其他期刊的2~6倍.关键词均以"桉树"出现的频次最高,其他主要关键词主要为品种与人工林.

Bibliometric Analyses of Chinese Eucalyptus Literature from the Past 30 Years

In order to understand the development of Eucalyptus related industries in China, key information was obtained for Eucalyptus literature published during the period 1987 to 2016 from the online database www.cnki.net, including quantity of literature/publications, subject coverage, research level, authorship, institutional affiliations of authors, project funding sources, cited references and key words. The results showed that literature quantity increased markedly over the years, with the number of publications for the periods of 1987—1996, 1997—2006 and 2007—2016 being 965, 2115 and 4631 respectively; the largest increase in number of publications occurred during the third phase (2007—2016). Most of the publications were focused on forestry subjects, and these accounted for about 70% of all publications on eucalypts. The research level was mainly based on engineering technology (natural science) and application fundamentals (natural science). During each of the three periods, the most published author had authored 11, 30 and 75 papers/publications respectively. Most publications were by authors affiliated with institutes located in Guangdong, Guangxi, Yunnan, Hunan and Fujian. Studies reported in the publications were funded mainly by projects of the National Science and Technology Research Plan and the National Natural Science foundation over the years examined (i.e. 1987—2016). Eucalypt publications during the period were mainly in the form of journal papers, with the number of these appearing in the journal 'Eucalypt Science and Technology' being 2 to 6 times the number that appeared in other journals. The most frequently used key word was "Eucalyptus"and other most common key words focused on species and plantations.
