【摘要】 为了深入了解全球草地退化研究进展,为相关领域的研究提供参考,本研究基于Web of Science数据源,利用Web of Science数据库所带的分析工具和Excel软件,对1992-2011年草地退化文献进行计量分析。结果表明,近20年国际草地退化研究年发文量呈指数增长;中国自2006年以来,对草地退化的研究增速显著,与世界同期增长水平相当;中国发文量和累计被引频次位居世界第2,但论文质量整体水平低于美国等发达国家;中国科学院在该领域的研究处于国内领先水平,值得同行关注;收录论文质量较高的3种期刊分别是英国的《Journal ofArid Environments》、美国的《Global Change Biology》和荷兰的《Geoderma》;研究热点涉及到退化草地植被生物量、土壤理化性质、空间格局变化,退化草地的恢复治理和保护等方面。更多还原

【Abstract】 To understand the research progress of the global grassland degradation and provide a reference for research in related fields,this study presented a quantitative analysis on grassland degradation research from 1992to 2011based on the Web of Science data source,by using bibliometric tools such as the database analysis tools and Excel.The results showed that in the past 20years,the annual number of articles on international grassland degradation research appeared an exponential growth.Research on grassland degradation has increased significantly since 2006in China,which was at a similar level of growth with the world.The number and citation frequencies of published articles in China were ranked in the second position in the world,but the overall level quality of articles was lower than the United States and other developed countries.The Institute of Chinese Academy of Sciences leads domestic position and worthy of peer attention in this fields.Three journals with the highest quality are Journal of Arid Environments,Global Change Biology and Geoderma.The research hotspots of grassland degradation research are vegetation biomass,physical and chemical properties of grassland soil,the change of spatial pattern,restoration,protection of degraded grassland,an so on.更多还原
