Abstract: Taihu Lake is the third largest freshwater lake in China and serves as a flood control and water resource regulation center for its basin. The impact of hydraulic engineering construction and its operational scheduling on the water ecology in the Taihu Lake Basin has been a pressing issue that needs to be addressed in the context of water resource development and ecological environment protection. This study comprehensively considers the service functions of the Taihu Lake Basin ecosystem and its ecological integrity characteristics to evaluate the ecological effects of comprehensive management projects in the basin. The results indicate that the ecological utility value of the comprehensive management projects in the Taihu Lake Basin is 0.24, representing a weak positive effect. To further enhance the ecological effects of the backbone engineering system in the Taihu Lake Basin, it is recommended to improve the water resource allocation capacity and water environment improvement capacity of the backbone projects. Additionally, mitigating the impact of projects on aquatic plants can be achieved through the restoration of artificial wetlands along the lakeshore. For dredging or widening projects, it is important to control the input of pollution loads to improve the recovery of benthic organisms and shorten the recovery time.
