Abstract: Bibliometric approach was employed in this paper to reveal the status and development trends of research on Changjiang (Yangtze) River flood based on SCIE and CSCD. The publication age, cooperative nations, core authors, author’s affiliations, and hot keywords were analyzed in detail. Results unveiled that: (1) the number of papers, in particular, SCIE papers, has surged after 1998, and the United States and Germany are top two countries which cooperate with China the most in the research. (2) The Chinese Academy of Sciences has been taking a leading role in contributing papers in English and Chinese languages, accounting for 31% and 23% of the total number of papers in SCIE and CSCD, respectively. Core authors of SCIE and the CSCD take up 27% and 21% of the total number of authors respectively. In SCIE, Journal of Hydrology was the top journal publishing research papers on Changjiang River flood, covering a proportion of 4%; in CSCD, Resources and Environment in the Yangtze Basin and Journal of Yangtze River Scientific Research Institute are top two periodicals publishing research papers on Changjiang River flood, each occupying a proportion of 7.28%. (3) Key words with a frequency over 20% included Three Gorges Reservoir, precipitation, climate change, sediment, and flood disaster. These key words had reflected the development of flood research in mechanism of disaster occurrence and disaster mitigation. Bibliometric information could provide reference for future flood related research in the Yangtze River Basin.

Key words: Changjiang (Yangtze) River, flood research, SCIE, CSCD, bibliometric, quantitative analysis, research trends
