水文循环是气候系统中的纽带,海陆气相互作用过程是一个复杂的物理过程。它们之间的耦合机制是气候变化的重要驱动力,对全球变化产生了深远的影响,是大气科学、水文学、海洋学及地球科学等领域较为关注的研究方向。为了综合全面地把握全球水文循环与海陆气耦合机制研究的国际发展态势,该文以该领域SCIE论文为数据来源,利用专业文献数据分析工具（Derwent Data Analyzer,DDA）进行论文数据的清洗和挖掘,对论文著录项中的国家、研究机构、来源出版物及其作者关键词等指标进行分析,研究并剖析了多年来该领域的发文态势和国际竞争格局,以期为宏观把握全球在该领域的基本研究态势提供重要参考。

Hydrological cycle is a link in the climate system, in which ocean-land-atmosphere interactions involve various complex physical processes. The couplings among the interactions, as important driving forces of climate change, have exerted far-reaching influence on the global climate change. Thus, studying the coupling mechanisms among ocean-land-atmosphere interactions in the hydrological cycle is a key research direction in the fields of atmospheric science, hydrology, oceanography and earth science. In order to explore the international development trend of this field, we took the publications (SCIE) as the literature data source, and used the professional analysis tool (Derwent Data Analyzer) to clean and exploit the data. By analyzing bibliographical particulars such as countries, institutions, journals and authors' key words in the paper description items, we obtained the international competition pattern over the years. The results presented here provide important reference for grasping the global basic research situation in this research direction.
