A restoration method of an aquatic ecosystem using porous structures is provided to promote the growth and rootage of plants by installing porous structures in a riverside area to the wanted width and length and supplying water required for seeds and plants sufficiently. The restoration method of an aquatic ecosystem using porous structures comprises the steps of: forming a concrete type porous structure having 10~70 percent porosity by mixing aggregate having the size of 5~40mm, cement, water and mixture and pouring in a mold(100); forming a flume pipe type porous structure by filling up the inside of an U or C-shaped or circular flume pipe with aggregate having the size of 5~40mm(200); forming a mesh type porous structure by filling up a rectangular frame composed of a metal screen with aggregate having the size of 5~40mm(300); selecting one or more from the porous structures(400); laying the selected porous structure under a place which is lower than the average water level in a river in the direction of a riverside space(500); guiding river water to the ground of the riverside space through the laid porous structure(600); and seeding or raising seedlings on the upper part of the riverside space in which river water flows(700). |
