Abstract：The temporal trend, regional distribution, subject type, author, organization and key works of researches are analyzed from the core database of Web of ScienceTM based on the bibliometrics method. The obtained results indicate that the study of the Three Gorges Reservoir has shown a sharp increasing tendency since the secondary period impoundment of the Three Gorges Reservoir in 2006. Most of research papers are from China and the major popular journals are Geomorphology and so on. Among the research institutions, Chinese Academy of Sciences, Beijing Normal University, East China Normal University have strong influences in this field. The major focusing issues include the effect of Three Gorges Reservoir on ecological environment, geological disaster, immigration in the middle and lower Yangtze River and reservoir region, among which ecological environment problem has attracted the most attention. Based on these analysis, development and application of models in this region, non-point source pollution, greenhouse gas emissions and their impact on climate change might become hot issues in the future.
