国内期刊生态学文献计量特征

Bibliometric regularity of ecological literatures published in Chinese journals

从文献计量学角度描述学科的发展动态,揭示学科发展规律是新学科发展进程的必要补充。论文以生态学37个分支学科的名称作为关键词,检索和统计了《维普科技期刊数据库》近15年文献。分析认为,国内期刊生态学文献符合指数增长规律,其中六个分支学科的文献所占比例较大,而生态经济、农业生态文献所占比例明显呈逐年下降趋势;文献量较小但增加迅速的学科有五个分支学科;发表文献的作者人数分布呈幂函数关系,发表10篇论文可为高产作者的分界点;发表生态学论文较多的主要机构集中于农林高校、综合性大学和中科院研究所;生态学文献在各种期刊中的分布符合布拉德福定律科学文献的分散与集中的规律。

To describe the trends and regularity of a discipline from a point ofbibliometric view is a necessary supplement for the development of a new discipline. We selected 37 sub-disciplines of ecology as keywords and searched for relevant literatures of past 15 years in （（VIE Chinese Scientific and technological Journal Database）） . It was found that the number of ecological literatures showed an exponential increase and the majority of literature increase was concentrated in six sub-disciplines. However, the proportion of literature in eco-economy and agriculture ecology was declining yearly. The number of literature in five sub-disciplines was small but increased rapidly in recent years. The number of authors in the literature showed a power function. A high-yield author could be defined by the publication of 10 papers. Main organizations that were affiliated with ecological publications were agricultural and forestry universities, universities, and institutes of Chinese Academy of Sciences. The distribution of ecological literatures in periodicals followed the Bradford Regularities.
