The invention discloses an integrated type ecological floating bed and the water body ecological system repairing technology thereof. A physical space of the integrated type ecological floating bed is formed by constructing a floating bed, a sinking bed, a buoyancy adjusting bottle, a lifting chain and an ecological barricading net, and integrates ecological components such as indigenous emergent aquatic plants, submerged plants, attached aquatic plants, fishes, snails and biochemical zeolite. The ecological behaviors of the ecological components are in linear cause and effect relation. The ecological components and organisms in the physical space form a semi-enclosed ecological subsystem with integral completeness. The upper line and the water body ecological system to be repaired are strong in coupling capability, and ecological factors in the lower line can exist stably. The damaged water body ecological system sufferring from one or a plurality of types of pollutions including water body eutrophication, heavy metal pollution, organic pollution and the like can be repaired by building pioneer communities and utilizing self-cleaning capability of the ecological system, pollution is removed, integral restoration or rebuilding of the damaged water body ecological system is promoted, simultaneously environment is beautified, and ecological deterioration of a healthy water body can be prevented.
