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 major research theme of the international scientific community across the century. With the increasing prominence of global environmental issues, global change research has drawn increasing attention from the international scientific community and the international community. Spatial observation is an indispensable and important method of global change research and plays an irreplaceable important role in the study of global change. Scientific and technical literature can reflect the development of scientific research. Thomson Data Anlyzer (TDA) and Ucinet are used to conduct data mining and analysis on the papers of Global Change Spatial Observations collected in the SCIE literature database from 1980 to 2009. The results show that the research involves many disciplines, a large number of studies began in 1990, and climate change, carbon cycle and land use change are the main research topics in this field. Remote sensing and modeling are the main research methods. Research areas have great advantages.
