中文摘要：

基于Web of Science数据库,利用文献计量学方法分析1900-2014年陆面过程研究的有关文献年际变化和学科分布,重点研究1991-2014年相关文献的研究力量、合作状况以及热点分布.结果表明：1）陆面过程是-个多学科交叉的研究领域,自1981年出现了第-篇有关陆面过程的文献,文献数量除个别年份略有波动之外,整体呈稳步增长趋势;2）从发文量、总被引次数和高被引论文篇数来看,美国、英国、法国、德国和加拿大等国的有关陆面过程研究的综合影响力较高;美国国家航空航天局（NASA）、美国国家大气研究中心、美国地质调查局、美国国家海洋和大气管理局（NOAA）和马里兰大学等机构的论文综合影响力较高;从篇均被引频次和高被引论文所占比例来看,英国、瑞士、荷兰、美国、瑞典和法国等国的论文质量较高;美国国家大气研究中心、NOAA、华盛顿大学、马里兰大学、NASA和科罗拉多大学等机构的论文质量较高.虽然中国在发文量上排第二位,但在篇均被引频次、高被引论文数及其所占比例等指标上并无优势.3）国家、机构和作者层面的合作度都呈现上升趋势,这表明此领域的研究规模不断扩大,合作关系更加密切.

英文摘要：

Based on the online version of Web of Science, we investigated the interannual variation and subject distribution of published papers on the land surface process for 1900 to 2014 by using the bibliometrics method, and focused on the research effort, corporative state and hotspot distribution during years from 2010 to 2014. The Results show that： 1） the land surface process is a interdisciplinary subject. The frst paper published on land surface process appeared in 1981. The number of papers shows a trend of steady increase generally. 2） According to the number of papers, citation frequency and the number of highly cited papers, the countries with higher comprehensive influence are the America, England, French, Germany and Canada on this topic. The organizations with higher comprehensive infuence include NASA, NCAR, Unit States Geological Survey, NOAA and University of Maryland. According to average citation per paper and the proportion of highly cited papers, the higher quality of papers were from the England, Switzerland, Netherlands, America, Sweden and French, as well as organizations of the NCAR, NOAA, Unit Washington, University of Maryland, NASA and University of Colorado. Although China was the second one in number of published papers, it is lack of advantage on average citation per paper or on the number and proportion of highly cited papers. 3） There was a growing trend in the cooperation degree among countries, organizations and authors. It indicates that the research scale is continuously extended, the cooperation and symbiosis are close and intimate more and more in this feld generally.
