基于文献计量的绿洲研究发展态势分析

A bibliometrical analysis of oasis research

以SCIE论文数据库作为数据源,采用美国汤森路透集团开发的专业数据分析工具TDA(Thomson Data Analyzer)和UCINET软件对1985—2014年(数据库更新时间为2014年11月30日)绿洲研究论文进行数据挖掘和定量分析。结果表明:(1)近30年来,绿洲研究论文数量逐年持续增长,年均增长率达19%;(2)从学科分类来看,研究论文主要涉及的学科包括地球化学与地球物理学、生物多样性保护、植物科学、生态学、地球科学等;(3)高频主题关键词分析得出,绿洲研究具有典型的地域性,GIS、遥感等技术手段应用于绿洲研究,更加关注干旱区水资源的开发利用;(4)中国的研究机构在绿洲研究方面非常活跃,特别是中国科学院,其论文量遥遥领先于澳大利亚塔斯马尼亚大学、美国加州大学等其他机构,但研究水平、影响力以及国际合作能力仍有待提升。

With the population expanding and economic development occurring rapidly,finding oases in dry areas is vital to ensuring the sustainable development of society. The bibliometric method is a common research tool used in various fields for systematic analysis. An effective bibliometric analysis based on the Science Citation Index Expanded（ SCIE）,published by Thomson Reuters,was carried out to provide insights into research activities on oases from 1985 to 2014. The Thomson Data Analyzer and UCINET were used for data mining and quantitative analysis of the papers on oasis research in the SCIE database. Analyzed aspects included the number of publications per year,the subject category,and the details of country and research institute. The objectives of this paper were to assess the current status and international influence of oasis studies in the world by analyzing and comparing characteristic features,and to provide directions for potential research in the future.The results indicated that the body of global research on oases is growing,especially since 1985. The development of oasis study can be divided into two stages： the embryonic and germination phase（ 1985—2002）,and the practice and rapid development phase（ 2003—2014）. Hot subjects mainly covered geochemistry and geophysics, biodiversity conservation,plant science, ecology, and geoscience. The research conducted in China dominated this field. The publications by the Chinese Academy of Sciences on this topic outnumber those of the University of Tasmania,University of California,and other institutions. However,the research quality and influence of the Chinese Academy,as well as itscapacity for international cooperation, need to be strengthened. Therefore, China should pay close attention to the development of international situations and progress in the study of oases,and should encourage China＇s relevant agencies to conduct systematic research,and actively promote cooperation on oasis research. In order to meet future demands and maintain a high level of oasis research and influence in China, we should continue to strengthen interdisciplinary cooperation and integration of research in natural science and social science.
