Claim 5:
6. The method for analyzing the disaster prevention and mitigation effectiveness of the ecological seawall according to claim 1, wherein the determining the development index of the tidal flats in front of dike of the target ecological seawall by using the preset Exner equation according to the two-dimensional bed surface change index comprises:
determining a bed surface change value of the target ecological seawall according to the two-dimensional bed surface change index; and
calculating the development index of the tidal flats in front of dike of the target ecological seawall according to the bed surface change value by using the Exner equation:, ∂
