国际干旱区研究发展态势简析

Analysis of status and trends of the international arid land research

基于SCI-E的国际干旱区研究科学计量指标明显上升,灰色预测显示未来仍将保持较大幅度的上升态势；美国是国际干旱区研究的科学活动中心,国际产出力指标居前的机构绝大多数出自美国；中国是国际干旱区研究产出力排名仅次于美国的第二大国；中国科学院是国际干旱区研究连续八年排名第一、产出力最高的科研机构；国际干旱区研究领域已经形成结构稳固、特征显著的核心支撑学科群。

Using gray theory, the scientometrical indexes based on the articles abstracted from SCI - E database on arid land research were analyzed and a gray model was built to predict the status and trends of the international arid land research. Results show that the various scientometrical indexes have increased obviously and will keep the strong growing trend in the following years （2006 -2008）. USA is the international scientific activity center of arid land research. The majority institutes with higher scientific output index are from USA. China ranks second in the international scientific output index only after USA. The Chinese Academy of Sciences has ranked first for the continuous eight years in the international institute scientific output index. A series of core supporting disciplines with firm structure and obvious features have formed in the field of the international arid land research.
