South-to-North Water Diversion Project;  sustainable development;  water resources management;  Ecology

Some lessons learned from large-scale water diversion projects abroad were introduced, and it was pointed out that it was necessary to conduct ecological environmental impact analysis before implementing large-scale cross-basin water diversion projects. Then, from the perspective of ecological environment, the possible adverse effects of the implementation of the middle route of the South-to-North Water Diversion Project were expounded, and the impact of the project on the capacity and probability of blooms in the middle and lower reaches of the Han River was discussed. Finally, countermeasures and suggestions for maintaining environmental sustainable development are put forward, so as to provide scientific basis for the implementation of the South-to-North Water Diversion Project.
