Abstract: With the expansion of water conservancy construction, numerous negative impacts have emerged in the ecosystems of rivers, lakes, and other water bodies, such as changes in hydrological patterns, destruction of biological habitats, and a decline in the self-purification capacity of water bodies. Ecological restoration has become an urgent issue to be addressed in the planning, construction, and operational management of water conservancy projects. This paper primarily focuses on the application research of ecological restoration technologies in water conservancy projects. The aim is to systematically review and evaluate the commonly used ecological restoration technologies, including river channel morphology restoration, ecological revetment, constructed wetlands, fish migration passage construction, and aquatic vegetation restoration. Additionally, it analyzes the applicable conditions, implementation effects, and existing deficiencies of these technologies in specific water conservancy projects.
