The green development concept is a core guiding principle for ecological civilization construction in the new era.As strategic infrastructure vital to the national economy and people's livelihoods

water conservancy projects must integrate green development throughout construction and management to achieve high-quality development in the water sector. This paper systematically explains the importance of implementing the green development concept in water conservancy project construction and management. By reviewing typical practices in major projects such as the Baihetan Hydropower Station

Huangdeng Hydropower Station

and the Hong Kong-Zhuhai-Macao Bridge

it identifies key technical pathways and management models for ecological protection

resource recycling

and intelligent management. It further proposes full-chain optimization measures covering planning and design

construction and operation

and monitoring and evaluation

providing theoretical and practical references for promoting the green

ecological

and intelligent transformation of water conservancy projects.
