In this study，we propose a comprehensive evaluation system based on the aspects of water hydrodynamics，water quality and socioeconomics to evaluate the IRSN effects and determine the optimal connectivity scheme.Mean flow velocity，maximum flow velocity and stagnant water ratio are selected as hydrodynamic indexes.Water quality improvement rate，concentration change index，water quality category ratio and water standard exceeding ratio are selected as water quality indexes.Economic benefits，costs and the net benefits are selected as the socioeconomic indexes.These indexes can reflect the improvement of the lakes from different perspectives，and the implications of the indexes are shown in Table 1.
