Ecological floating island device

The invention discloses an ecological floating island device for the water ecological environment-engineering field and the water pollution control field. The ecological floating island device comprises one or two floating island bodies and two or more of the floating island bodies are connected; each floating island body comprises one or two floating carriers, and two or more floating carriers are connected. Each floating carrier comprises a floating plate, a floating basket and a floater, the floating plate and the floater are connected with each other, and the floating basket is fixed on the floating plate, and recessed downwards from the top to form a planting cavity and a filter material cavity. The reed is planted in the planting cavity, and the filter media cavity is filled with volcanic filter media. The buoyancy of the floating plate and the floater is greater than the sum of the weight of the basket, the maximum biomass of the reed in the environment and the weight of the volcanic filter media, and
