摘要
地球关键带自2001年由美国国家研究理事会(NRC)正式提出后,美国、南非、中国和欧盟等国家和地区相继组织和部署了地球关键带研究项目,制定相关的研究计划,同时,建设了长期野外观测网络站点,以加强和促进地球关键带研究。本文基于SCIE文献数据库中2001~2015年与地球关键带研究相关的论文、研究综述和学术会议论文等分析发现:近15年,国际地球关键带研究论文总体呈增长趋势,并存在较大的波动;美国及美国研究机构在地球关键带研究的论文数量方面占绝对优势,中国研究机构的研究实力仍需进一步提高;从研究热点变化来看,各主要国家和机构所共同且最为关注的研究主题为关键带、水文学、土壤等;此外,跨学科研究已成为地球关键带研究的重要组织模式之一。最后,结合我国实际,提出了未来我国应该重点开展的4个研究方向。
Earth Critical Zone was formally proposed by the American Research Council （NRC） in 2001. Then United States, South Africa, China and other countries, and relevant international organizations, such as the European Union, organ- ized and deployed research projects, as well as developed the related research plan, established observation web site for a long time,to strengthen and promote Earth Critical Zone research. In this paper, based on SCIE database, the relevant pa- pers,research reviews, conference papers and other relevant documents from 2001 to 2015 were retrieved. Based on the Earth Critical Zone studies,the results show that：1 ） the overall research papers of Earth Critical Zone show the fluctuation growth trend ;2） America and its research institutions have absolute advantage in Earth Critical Zone research, but Chinese institutions still need to further improve the research strength ; 3 ） From the hot spot change, research topics,including critical zone, hydrology, soil, ete has become the most concerned for the major countries and institutions ; 4 ） Interdisciplinary re- search is key important organization mode to Earth Critical Zone research. Finally, the four future key research directions of Earth Critical Zone in China are put forward.
