The invention discloses an ecological wave-weakening water conservation revetment structure. The ecological wave-weakening water conservation revetment structure is characterized in that an emergent plant wave-weakening area is arranged below a high water level of a revetment, a hygrophyte corrosion prevention area is arranged above the high water level until the top of the revetment, and an economical plant dike dam area is arranged on the top of the revetment and the remaining space. One to two rows of wave-weakening piles are arranged on the side, close to water, of the emergent plant wave-weakening area, wherein large emergent plants are planted in the emergent plant wave-weakening area in a wide and dense mode, and the emergent plants are mixed in the shape of strips and arranged parallel to the water flow direction. Hygrophytes with luxuriant roots and leaves are planted in the hygrophyte corrosion prevention area in a wide and dense mode, and the hygrophytes are mixed in the shape of strips and arranged parallel to the water flow direction. The economical plant dike dam area is of a windbreak tree belt structure formed by mixing economical trees and shrubs, wherein ecological garden dike roads are paved in the windbreak tree belt structure in a natural style for relaxation and sightseeing of tourists. The ecological wave-weakening water conservation revetment structure not only has the remarkable water conservation embankment effect, but also has the advantages of being ecological, attractive in appearance, and capable of weakening waves and enhancing effects.
