摘要
银杏是中国的特有树种,仅有一科一属一种,有垂枝银杏、裂叶银杏、黄叶银杏、斑叶(花叶)银杏、叶籽银杏和异叶银杏等几个变种。20世纪70年代后期,银杏始脱离半林半果的状态,作为果树集约栽培,但生产栽培与科学研究发展较快,产生的文献数量不亚于其他树种。经对1994—2004年专业期刊公开发表的银杏文献进行计量分析表明:载文期刊474种,总文献量2284篇,署名文献2269篇,第一作者1348人。主要作者群为各类院校的教学科研人员。确定了57位核心作者,11种核心期刊。
Gingkgo is native to China, has 1 family, 1 genus and 1 species, but has some mutations, e.g.G. biloba var. pendula Carr.,G. biloba var. lacinia Carr., G. biloba var. aurea Beiss., G.biloba var varie Carr., G. biloba var. epiphylla Mak. and G.biloba var. heterophylla T.B.Chao et Z.X.Chen.Commercial cultivation began in the seventies of the 20th century, but cultivation and research has been developed rapidly. Bibliometric analysis of gingkgo literatures published in professional journals during the period from 1994 to 2004 showed that the gross volume of literatures was 2284 paper and the number of onymous literatures was 2269. The primary authors were 1348, mainly research staff of research institutions. The paper has confirmed 57 core authors and 11 core journals.
