With green and ecology as the core theme , the project is the first cross-provincial ecological restoration project in China. Through the design of shoal wetlands, the conceptual form of simulating the migration of fish is introduced. The water culture from the south of the Yangtze River is integrated into the spatial composition, architectural modeling, plant system and furniture construction, and the sponge system is combined with the landscape design to realize the positive design mode. The restoration of Yuandang ecosystem truly illustrates the “New Space of Jiangnan Culture”.
