Abstract:This paper studies the restoration and protection of water ecology in water conservancy and hydropower projects, aiming to solve the damage to water ecosystem caused by the construction and operation of water conservancy and hydropower projects. Firstly, the background and purpose of the research are introduced, and the research status at home and abroad is summarized. Then, the characteristics and functions of water ecosystem are expounded, the basic concepts and principles of water ecological restoration and protection are explained, and the importance and challenges of water ecological protection are emphasized. Then, the impact of water conservancy and hydropower projects on water ecology is analyzed, including the type and scale of the project, the response of water ecosystem and the impact mechanism. On this basis, the technical means and methods of water ecological restoration and protection were put forward, including technical classification and selection, ecological water level management and regulation, ecological channel construction and management, vegetation restoration and protection, and water quality purification and protection technology. The problems of water ecological restoration and protection, including ecosystem destruction, loss of species diversity and loss of ecological service function, were further discussed. In addition, the national water ecological restoration and protection policies and regulations, environmental impact assessment and supervision of water conservancy and hydropower projects, water ecological restoration and protection management mechanism and experience were studied. Finally, through the summary and analysis, the conclusion is drawn, and the future research direction is prospected.
