| Abstract: | To investigate the develop trends and the hot spots of the global change research, we used TDA analyzer to data mining based on WOS (Web of science) core collection database. We found that the annual number of publications increased rapidly in recent years, and a total of 145 849 papers were published in this field. The numbers of publications and citations in USA were far higher than those in other countries. However, the Chinese Academy of Sciences published 5 815 papers and was in the first rank of all the institutions. The research areas in the global change are mainly in environmental science and ecology, geography, meteorology, and atmospheric science, focusing on global warming, greenhouse gas effect, carbon and nitrogen cycle, biodiversity conservation, and sustainable development by using remote sensing, satellites, models, and GIS. |
