The invention discloses an ecological
floating island and a building method thereof, the island comprises a
floating island unit outline border (1), an outline border cover (2), floating-body filler (3), planting cups (4) and planting pipes (5). Under the synergic action of the floating-body filler (3), microorganisms growing on the floating-body filler (3) and
plant root systems, optimal biological balance can be established, so that polluted
water body can be treated continuously; meanwhile, the ecological
floating island of the invention can be suitable for various plants, and
crop rotation or interplanting can be carried out to achieve the effects of stereo planting and four-season planting, and
treatment effect and landscape effect can be kept all year round; by adopting the planting cups (4) and the planting pipes (5), the
workload for building the ecological floating island can be reduced and the
survival rate of the cultivated plants is improved; in addition, the ecological floating island of the invention can be assembled in a laminating way, thus improving the
pollution control efficiency greatly.
