Abstract

The aquatic ecosystem of a watershed is degraded due to the combined effects of hydrodynamic changes, water pollution, and habitat fragmentation. A framework for aquatic ecological restoration centered on habitat reconstruction is needed. Taking the middle and lower reaches of the Han River as an example, a two-dimensional hydrodynamic-water quality model is combined with a habitat suitability index to create an ecological quality index (EQI) and a connectivity index (CI), thereby identifying the types of degradation in different habitat units and the order of restoration. Based on this, scenarios such as flow improvement, structural restoration, water quality management, and comprehensive restoration are planned. A multi-objective evolutionary algorithm is used to explore the Pareto solution set in the “ecological benefits-engineering cost-robustness” space, and then a phased implementation path is formulated for the near-term, medium-term, and long-term. The results show that, with limited investment, the comprehensive restoration scheme can significantly enhance EQI and CI. For river sections classified as high priority, the improvement in habitat connectivity is particularly significant, which can provide quantitative support for the design of watershed aquatic ecological restoration projects.
