PURPOSE: A river revetment facility for ecosystem protection is provided to use the river revetment facility as a spawning place of an underwater ecosystem and as a shelter in a great flood, to protect the underwater ecosystem to the utmost. CONSTITUTION: A river revetment facility for ecosystem protection comprises a fish movement passage member(200), a fish-spawning member(300), a fastening bolt member(400), and current velocity reduction members(500). In the fish movement passage member, plural movement passage holes(220) and fastening bolt holes(230) are formed in a movement passage body(210), a spawning member connection hole(240) is formed in the movement passage body, fixing-fastening holes(250) are formed to the side of the longitudinal bottom, and semi-circular movement passage holes(260) are formed to the upper edges. The fish-spawning member is connected to the rear of the fish movement passage member after the fish movement passage member is installed. One side of a fish-spawning member body(310) is rounded and the other side is vertically formed. The longitudinal sides of the fish-spawning member body are open. A protruded circular part(320) is formed to the vertical part of the fish-spawning member body. The fastening bolt member connects plural fish movement passage members. The fastening bolt member is fastened and fixed with a nut while a bolt part is fastened to the fastening bolt hole. In the current velocity reduction member, a bolt part(520) is integrally formed to the rear of a triangular body(510). The current velocity reduction member is fastened and fixed with a nut while the bolt part is fastened to the fastening hole.
