利用SCIE数据库,统计分析了1995-2009年间的生物多样性(biodiversity)研究文献,可以看出:大量论文集中在少数期刊中,而少数论文则分布于大量期刊上。生物多样性的研究力量的分布虽然分散,但美国在生物多样性研究领域具有领先优势,高校和科研单位是名副其实的生物多样性研究领域的主力军;生物多样性研究文献涉及的学科类别以生态学、环境科学和生物多样性保护为主;本研究中达到“经典文献”标准的文献很多,从一个侧面说明该学科非常活跃;10种期刊2008年的影响因子与h指数的排序基本相同。
Using the SCIE database, a statistical analysis of the literature on biodiversity between 1995 and 2009 shows that a large number of papers are concentrated in a few journals and a few are distributed in a large number of journals. Despite the fragmented distribution of biodiversity research power, the United States has a leading position in the field of biodiversity research. Universities and research institutes are the main force in the field of biodiversity research. The disciplines involved in biodiversity research literature are ecological Learning, environmental science and biodiversity conservation. There are many literatures that have reached the standard of “classical literature” in this study, indicating that the discipline is very active from one aspect. The rankings of the influencing factors and h indices in 10 journals in 2008 are basically the same.
