It can be seen from the evaluation results（Table 7）that the lakes under Scheme V have the largest mean flow velocity and the lowest stagnant water ratio.In addition，the lakes under Scheme V have the largest water quality improvement rate and the largest concentration change index.As for the aspect of the socio-economic indexes，it is still Scheme V that can bring the most net benefits.Moreover，Scheme V can improve both the hydrodynamic condition and the water quality condition of the six lakes simultaneously by diverting water from the Donghu Lake and the Liangzi Lake.In summary，Scheme V is chosen as the optimal scheme.
