Abstract: Lake bay area is the forefront of urban lakes receiving pollutants and a key link in improving the ecological environment of urban lakes. We took Tangxun Lake in Wuhan, a typical shallow water urban lake in the middle and lower reaches of the Yangtze River as an example. Focusing on the typical ecosystem of the lake bay area, the characteristics and key influencing factors of the lake bay area ecosystem were accurately identified through in-depth understanding of its state, degree of disturbance and succession direction. On this basis, the study proposed to use urban lake bay areas as ecological buffer zones for the main lake, and to promote the overall ecological recovery and sustainable environmental improvement of the main lake from point to area. At the same time, based on the ecological environment characteristics of urban lake bay areas, strategies and suggestions for ecological recovery of lake bay areas had been proposed. The research results can provide references for improving the water environment of urban lakes, restoring degraded ecosystems and enhancing ecological service functions.
