The bank slope of the fluctuating zone of the Yangtze River is repeatedly scoured for years as the water level rises and falls，which results in the vegetation deterioration and ecological fragility and makes the fluctuating zone lose its function of filtering and intercepting. Taking the area with the water level ranging from 160.00 m to 170.00 m in the Yangtze River in the Guangyang Bay area of Chongqing as an example，this paper studies the treatment scheme for the fluctuating zone and adopts the method of “ecological net mat for soil consolidation + vegetation” to maintain the shoreline stability. In addition，the waterfront landscape zone and a multi-level and complex compound forest system of the fluctuating zone are formed after vegetation growth. The results show that the soil retention rate is more than 98%，and the project implementation has a favorable effect.
