Abstract: As a pivot in the Yangtze River ecological system, the Poyang Lake Basin plays a crucial role in the construction of the Yangtze River Economic Belt. The Poyang Lake region and its five major tributaries boast wide banks and waterfront zones. The spatial differences and major problems of waterfronts in vertical and horizontal directions were analyzed. On this basis, key technologies in ecological flood control embankment, ecological water conservancy combined with schistosomiasis prevention and control, as well as ecological bank purification were put forward. By analyzing the functional attribute and application scope of each single key technology, the overall layout of key technologies coordinated with different regions is defined. The key technology system includes object layer, function layer, technology layer, effect layer and application layer. The present research lays a foundation for technology integration and application in typical areas within the five tributaries and lake area of Poyang Lake, and also holds reference value for other similar rivers-lake systems.

Key words: ecological bank, waterfront, key technology system, Poyang Lake region and its five major tributaries, ecological flood control embankment, ecological water conservancy combined with schistosomiasis prevention and control, ecological bank purification
