PURPOSE: Provided is a step-shape ecological structure to be installed in a river side or a lake side to provide a slow slope and the habitat of fishes and aquatic organism. CONSTITUTION: The structure comprises a step-shape frame(10) with inner space(13), a plurality of horizontal plates(11) and a plurality of vertical front plates(12) for providing steps at the front side of the frame(10), a plurality of detachable panels(11a) attached on the corresponding horizontal plates(11) to cover the upper surface of the each step, a plurality of penetrating holes(12a) formed on the corresponding vertical front plates(12), a plurality of brackets(14) fixed to the vertical front plates(12) in vertical direction at regular intervals, a stripe-shape supporting members(15) for partially covering the penetrating holes(12a) of the vertical front plates(12) by being supported by the brackets(14) to prevent fillers(16) in the inner space(13) from being flowing off, floating members(17) fixed to the supporting members(15) and the fillers(16) for filling the inner space of the step-shape frame(10) in such a way of having pores therebetween to provide habitat of fishes and aquatic organisms.
