Abstract:
Yangtze River is not only the largest river in China, but also the most important water source in China. Protecting the Yangtze River is the basis for the high-quality development of the Yangtze River economic belt. Starting from the analysis of the ecological and environmental problems of Yangtze River, the achievements made in the implementation of the great protection of Yangtze River in the past six years are summarized, the deep-seated problems existing in the ecological environment, scientific solutions and management countermeasures are discussed，and comprehensive countermeasures and suggestions for the protec- tion of Yangtze River in the future are put forward. The analysis shows that the river water quality of Yangtze River has im- proved significantly, but the recovery of lake water quality and ecosystem is slow. The restoration of rare and endemic species, the restoration of water ecosystem integrity and the control of watershed non-point source pollution are long-term and complex tasks. Under the dual influence of climate change and human activities，the evolution mechanism and restoration technology of Yangtze River ecosystem? the joint regulation method of hydraulic engineering groups with full consideration of ecological needs, the development of comprehensive monitoring and digital twin technology of the river basin,and the improvement of vari- ous mechanisms of Yangtze River protection are the focus of future scientific research and river basin protection. Only through comprehensive observation, systematic scientific research and adaptive management measures?the goal for both high-quality de- velopment o￡ Yangtze River economic belt and beautiful China can be achieved.
