Ecological bank-protection vegetation structure

The utility model discloses an ecological bank-protection vegetation structure which is arranged on the junction of a river bank slope and a riverbed. The ecological bank-protection vegetation structure is characterized in that a first layer of horizontally-arranged alloy steel-wire cage bodies is piled on a smooth position of the riverbed, every two adjacent alloy steel-wire cage bodies are fixedly connected with each other by utilizing a steel wire, a second layer of alloy steel-wire cage bodies is piled on the first layer of alloy steel-wire cage bodies, a third layer of alloy steel-wire cage bodies is piled on the second layer of alloy steel-wire cage bodies to form a stepped bank slope, each alloy steel-wire cage body of each upper layer is pressed between two alloy steel-wire cage bodies of the adjacent lower layer, the contact area of the alloy steel-wire cage bodies of each upper layer with the alloy steel-wire cage bodies of the adjacent lower layer is half of the entire area of each alloy steel-wire cage body, a plant mat is arranged in each alloy steel-wire cage body, and each plant mat comprises a substrate and plant roots or seedlings of different types which are planted on the substrate. By adopting the ecological bank-protection vegetation structure, the river bank can be maintained stable, the severe evolution of the riverbed can be prevented, a condition can be created for the growth of the plants, the project is well matched with the environment, and the requirements on the ecology and landscape aspects can be met.
