生物多样性是人类赖以生存的重要物质基础，中国在生物多样性研究领域做了大量的工作，发表了众多有价值的学术论文。通过文献计量方法，对2009-2018年中国生物多样性研究领域WOS（Web of Science）和CNKI（中国知网）数据库收录论文的数量及被引情况、载文期刊分布等进行统计；并借助CiteSpace文献可视化软件，分析论文的作者合作、合作机构、国家（地区）合作和研究热点等。结果表明：2009-2018年间，中国生物多样性研究领域共发表论文17035篇，其中CNKI收录文献13365篇，WOS收录文献3670篇；年度发文总量以及WOS年度发文量总体呈上升趋势；CNKI文献被引频次最高的论文是于2009年发表在《生物多样性》上的"植物群落清查的主要内容、方法和技术规范"，WOS文献被引频次最高的论文是于2011年发表在Global Change Biology上的"TRY-a global database of plant traits"；朴世龙教授、骆亦其教授和唐志尧教授等是基于WOS文献的生物多样性研究领域核心作者，王得祥教授、马克平研究员和张文辉教授等基于CNKI文献的生物多样性研究领域主要作者；WOS文献与CNKI文献发文量最多的机构均为中国科学院所属相关科研院所；与中国合作的国家或地区共有106个，包括美国、英国、澳大利亚等；《生态学报》和Global Change Biology分别是该领域中文和外文文献的重要期刊载体；基于WOS文献的研究热点为气候、土壤等环境因子变化对物种多样性的影响研究以及基于微卫星分子标记技术的物种遗传多样性研究，基于CNKI文献的研究热点为环境因子与群落结构的关系研究。上述研究结果从收录论文的角度，定量、客观、科学地描述了2009-2018年中国生物多样性研究状况及研究热点，以期促进中国生物多样性的深入研究，并为相关领域学者凝练研究动向和科学问题等提供参考信息。
Biodiversity is an important material basis for human survival. China has done a lot of work in the field of biodiversity and published many valuable papers. With the bibliometric method, this study made statistics on the number and citation of papers included in the Web of Science (WOS) and in the China National Knowledge Internet (CNKI ) database of biodiversity research in China from 2009 to 2018. Additionally, the author cooperation, cooperative institutions, national (regional) cooperation and research hotspots of the papers were analyzed using CiteSpace. The results showed that there were 17035 papers in the field of biodiversity research in China from 2009 to 2018, including 13365 CNKI papers and 3670 WOS papers. Both the annual total number of papers and the annual number of WOS papers showed overall upward trends. The title of the most frequently cited CNKI papers was ‘Methods and protocols of plant community inventory’, which published in the journal Biodiversity Science in 2009. And, the title of the most frequently cited WOS papers was ‘TRY - a global database of plant traits’, which published in the journal Global Change Biology in 2011. Professor Piao Shilong, Professor Luo Yiqi and Professor Tang Zhiyao were the core authors in the biodiversity research field based on the WOS literatures. Professor Wang Dexiang, Professor Ma Keping and Professor Zhang Wenhui were the primary authors in the biodiversity research field based on the CNKI literatures. The institutions with the largest quantities of WOS papers and CNKI papers were all the research institutions from the Chinese Academy of Sciences. There were 106 countries or regions that cooperate with China, including the United States, the United Kingdom, and Australia. The journal analysis showed that Acta Ecologica Sinica and Global Change Biology were the primary journal carriers of Chinese and foreign papers in this field, respectively. There were two research hotspots based on WOS papers, one was the effects of environmental factors such as the climate and soil on species diversity, and the other was the analysis of genetic diversity of species using microsatellite molecular marker technology. The research hotspots based on CNKI papers were the relationships between environmental factors and community structure. The present study quantitatively and objectively investigated the status and hotspots of biodiversity research in China from 2009 to 2018, which could promote in-depth in this field and provide reference information for scholars in the relevant fields to refine their research directions and allow them to address specific scientific issues.
