生物多样性研究是综合性和高度交叉性的跨学科研究领域,是1997年底Science周刊上预测的1998年及近期的6个重大科学热点之一.检索1986-2008年间SCIE文献数据库中关于生物多样性的研究论文(article,proceedings paper和review),利用Thomson Data Analyzer(TDA)分析工具和Aureka分析平台进行数据挖掘.分析表明,该研究涉及多个学科领域,近年来在生态学领域的论文数量增加最多,而生物多样性保护、进化生物学、生物化学与分子生物学方而的论文增长速度较快.生物多样性研究越来越重视全球变化和人类社会对生物多样性的影响,DNA技术和基因工程等先进技术在生物多样性研究和保护中的作用也更加突出.
Analysis on situation and tendency of international biodiversity research
Study on the biodiversity is a comprehensive and interdisciplinary subject. By the end of 1997, the Science Magazine made a prediction about that Biodiversity would be one of the six research hotspots in 1998 and in the near future. Research papers on biodiversity during 1986 to 2008, which included articles, proceedings papers, and reviews, were retrieved from Science Citation Index Expanded (SCIE) database. The hotspots and development trends of the biodiversity research were extracted based on data mining by using the Thomson Data Analyzer (TDA) and Aureka analysis platform of Thomson Reuters Company. The results indicated that biodiversity research involved many interrelated fields, such as ecology, environmental science, botany, biodiversity conservation, genetics, marine and freshwater biology, microbiology, agronomy, and so on. Among these fields, biodiversity conservation, genetics, biochemistry and molecular biology had shown relatively fast increase in paper number. The International biodiversity research paid more and more attentions on microsatellites, AFLP, and biogeography. Its hotspots mainly focused on plant diversity development, biodiversity conservation, species richness, genetic diversity, sustainable management, climatic change, forest, soil, ecosystem, etc. The international biodiversity research focused more on the interaction between human society and biodiversity. In addition, the advanced technologies, such as DNA technology and genetic engineering, played a more prominent role in research and conservation of biodiversity.
