【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。
[Abstract]:Since the Earth critical zone was formally proposed by the National Research Council of the United States in 2001, the United States, South Africa, China and the European Union and other countries and regions have organized and deployed the Earth's critical zone research projects. A related research plan has been developed and a long-term field observation network site has been built. In order to strengthen and promote the study of the Earth's critical zones, this paper is based on the papers related to the study of the Earth's critical bands in the SCIE literature database from 2001 to 2015. It is found that in the past 15 years, the research papers on the critical zone of the earth have been on the increase and fluctuated. The United States and American research institutions have an absolute advantage in the number of papers on the Earth's critical zones, and the research strength of Chinese research institutions still needs to be further improved. From the point of view of the change of research hot spots, the key zones, hydrology, soil and so on are common and most concerned by the major countries and institutions. In addition, interdisciplinary research has become one of the important organizational models for the study of the critical zone of the earth. Finally, combined with the reality of our country, four research directions which should be carried out in China in the future are put forward.

【正文快照】： 1引言地球关键带(Earth Critical Zone)的学术概念由美国国家研究理事会(NRC)于2001年正式提出[1]。自此,对于地球关键带的概念探讨相继展开,且从不同角度对地球关键带的概念进行了阐述。例如,2005年美国国家科学基金会(NSF)发布报告[2]指出,地球关键带包括地球的最外部表面,
