Ecological gabion water purification structure

The utility model relates to an ecological gabion water purification structure which is composed of gabions, biological carrier window pieces and plant growth matrix blocks. The structure body is composed of three gabions in an upper layer and a lower layer, and the gabions are stacked up and down to form an L-shaped retaining wall structure. Vesuvianite and zeolite are filled in the gabion, and an anti-leakage net is laid on the inner wall of the gabion. Planting matrix layers are arranged on the upper surfaces of the upper gabion and the lower gabion, aquatic plant seed layers are arranged above the planting matrix layers, emergent aquatic plants are planted in the upper gabion, and submerged plants are planted in the lower gabion. The outer wall of the side, facing the water body, of the lower-layer gabion is provided with shutter type biological carrier window pieces, the window pieces are connected with the gabion walls through rotating shafts, and nutrient grooves are formed in the surfaces of the windo
