Abstract 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.
