我国保护生物学研究于1990年开始起步,目前正处于快速发展阶段。为全面了解我国保护生物学领域的研究现状,作者在《中国学术期刊全文数据库》和ISI Web of Knowledge中,用"保护生物学"和"conservation biology"作为检索词,检索了中国学者在国内外期刊上发表的与保护生物学相关的中英文文献,采用文献计量法定量分析了我国保护生物学文献的年代分布、期刊分布,并利用文献的题录信息统计了保护生物学的研究力量、基金项目和研究地区分布,以及研究物种类群等指标。结果表明,我国保护生物学的研究力量的分布虽然分散,但也已经形成从事研究的核心研究人员群体、研究机构群体;中、英文保护生物学文献的期刊分布都存在离散性与集中性并存的现象,即: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。我国出版的保护生物学专业期刊只有《生物多样性》一种,迫切需要创办一种英文保护生物学专业期刊;研究基金的支持来源广泛,中文文献主要是国家自然科学基金和省级基金,英文文献则主要是国家自然科学基金和国际基金;中英文文献中的研究地点都倾向于生物多样性较高的西南和华南地区;研究对象主要是植物、哺乳类和鸟类,单一物种的研究中濒危物种占90%以上;物种多样性调查和遗传多样性检测的研究较多,但针对保护方法和实践的研究则不足。
