STUDIES ON THE INFLUENCE OF THE THREE GORGES PROJECT ON THE DOWNSTREAM AND ESTURIAL ENVIRONMENT IN YANGTZE RIVER

This paper summarized the essential variation of the dynamic factors of the downstream flow and sediment caused by the construction of the ThreeGorges Project, and its main influence on the ecology and environment of the downstream and estuary region by it. Some problems which are difficult to determine at present were analysed in detail to provide a reasonable scientific basis to the multiple development and environment protection of the downstream and estuary region of Yangtze River.
