全球变化空间观测研究的文献计量分析

Bibliometrical Analysis for Space Observations of Global Change Research

全球变化研究是国际科学界跨世纪的重大研究主题。随着全球环境问题的日益突出,全球变化研究日益得到国际科学界和国际社会的高度关注。空间观测是全球变化研究的一种不可或缺的重要方法,在全球变化研究中发挥着不可替代的重要作用。科技文献能够反映科学研究的发展动态,利用Thomson Data Anlyzer(TDA)和Ucinet对SCIE文献数据库中收录的1980～2009年间的全球变化空间观测研究论文进行数据挖掘和分析。结果表明,该研究涉及多个学科领域,大量研究始于1990年,气候变化、碳循环、土地利用变化等是该领域的主要研究内容,遥感、建模等是主要的研究方法,美国在该研究领域具有很大优势。

Global change research is a cross-century research theme organized by the international scientific and technological circles. It is now getting more and more attentions while the global environment problems become prominent day by day. Space observations is an indispensable and important method for global change research, it plays an important role in the research process. The tendency of scientific research could be reflected by bibliometrical analysis. Thomson Data Analyzer and Ucinet were used to do data mining and analysis of papers about space observations of global change research from SCIE database in this paper. The results indicate that space observations of global change research involved many interrelated fields, many researches were Started from 1990, climate change, carbon cycle,land use change etc are the major research contents,remote sensing,modeling etc are the major research methods, The United States has a great advantage in this field.
