An ecological engineering method for damping impact force of water flow includes the steps of: placing at least one object defined with a cavity opening on the bottom of a stream providing the cavity opening of the object and a canal to have an angle of 10 to 90 degrees therebetween and arranging a plurality of objects to have gaps formed therebetween. With the cavity openings of the objects or the gaps formed between the objects to be served as habitats and sanctuaries for fishes, other aquatic organisms and aquatic plants, large quantitative of water flow to directly impact on biological habitants can be anti-dragged and damped, and therefore a food chain for fishes and other aquatic organisms can be established.一種可減緩水流沖擊力之生態工法,係將至少一具有一空洞口之物件置於溪流底部,以及使該空洞口與水道形成10~90度角,並將該物件排列成具有空隙;俾藉該物件之空洞口或空隙作為魚類及其他水生物、水生植物之棲息、庇護處所,且可減阻及減緩大量水流直接沖擊生物棲息、庇護之處所,進而建構魚類及其他水生物之食物鏈。10...U型溝塊11...空洞口20...空心磚21...空洞口30...水泥管31...空洞口90...溪流
