Changes of river-lake-catchment interaction due to the climate changes and human activities have brought about fluvial processes of Poyang Lake and estuaries of Five rivers, and caused large influences on the local hydrology, water environment, ecology and socioeconomic development. This paper reviews fluvial processes of Poyang Lake and estuaries of Five rivers, changes of river-lake-catchment and driving forces, and relative regulations. At last, some directions for further studies are suggested in the study.
