Floating type ecological wetland system suitable for coastal bay and construction method

Abstract

The invention discloses a floating type ecological wetland system suitable for a coastal bay and a construction method, aims at solving the current ecological environment problems of coastal ecological shoreline degradation, biodiversity reduction, ecological function degradation, environmental bearing capacity reduction and the like, and can build a habitat for coastal zone organisms, enrich the biodiversity and improve the water quality of shallow bay coastal water areas. The system comprises a plurality of floating island single bodies which are connected in series and spliced, a plurality of lifting ropes are hung at the bottoms of the floating island single bodies, a plurality of oyster shells are arranged along the lifting ropes, and salt-resistant and flood-resistant emergent aquatic plants are planted above the floating island single bodies. The method comprises the following steps: manufacturing floating island monomers; transplanting salt-resistant and flooding-resistant emergent aquatic plants cultivated in a laboratory or a seedling field to the upper part of the floating island monomers according to a certain interval; placing the floating island monomers in a laboratory cultivation room or an offshore aquaculture area, and waiting for rejuvenation and growth of plants above the floating island monomers and attachment of young oysters; and splicing multiple cultured floating island monomers in a multi-stage series connection mode.

Description

technical field [0001] The invention belongs to the technical field of coastal ecological restoration, and in particular relates to a floating ecological wetland system suitable for coastal inner bays and a method for constructing the system. Background technique [0002] Floating ecosystems, also known as artificial floating beds, ecological floating islands, etc., are usually divided into three types according to their functions: wave dissipation type, water quality purification type and habitat type. Floating ecological wetland technology is a soilless cultivation technology. Plants are cultivated on the water surface through floating bed facilities. On the one hand, plants are used to absorb nutrients such as nitrogen and phosphorus in the water during the growth process, making them an integral part of the plant body. Maintain its own growth; on the other hand, the huge surface area of ​​plant roots can absorb a large amount of suspended solids in the water body, provid...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims at the ecological environmental problems such as the degradation of coastal ecological shoreline, the reduction of biodiversity, the degradation of ecological functions, and the decline of environmental carrying capacity. The wetland system can create a habitat for organisms in the coastal zone, enrich biodiversity, and improve the water quality of shallow bay coastal waters
