Method for constructing integrated submarine forest

Abstract

The invention relates to a method for constructing an integrated submarine forest and belongs to the technical field of seabed construction. The method comprises the steps of: 1) selecting and reforming the bottom material of the submarine forest and 2) multiplying large-scale sea-plants, wherein the bottom material of the submarine forest can be divided into three types: ledge substrate, cobble substrate, and sand and mud substrate; the bottom material of the submarine forest is selected and reformed in different manners according to different substrates; transplanting the large-scale sea-plants, such as sea-tangle, undaria pinnitafida, and the like, in the ledge substrate free from alga; transplanting alga by binding a sea-tangle collector after constructing reef on the cobble substrate and sand and mud substrate; and then manually planting and transplanting zostera marina on the sand and mud substrate. The method of the invention is reasonably designed, can efficiently solve the problem of insufficient submarine plants, can bring much more economic benefits to sea area, and can prevent the floated bottom sediment, muddy water and less dead shellfish.

Description

technical field [0001] The invention relates to a method for building an integrated seabed forest, belonging to the technical field of seabed construction. Background technique [0002] The marine environment is the habitat on which marine organisms depend for survival. The quality of the marine environment directly affects the stable survival and continuous reproduction of marine organisms. [0003] However, because the relationship between the sustainable use of marine biological resources and the marine ecological environment and the law of interaction are not well grasped, and there is a lack of scientific, reasonable and unified marine resource development planning, large-scale high-intensity mariculture is carried out in a "horse race around the field" style.

[0003] However, because the relationship between the sustainable use of marine biological resources and the marine ecological environment and the law of interaction are not well grasped, and there is a lack of scientific, rational and unified marine resource development planning, large-scale high-intensity mariculture is carried out in a "horse race around the field" style. Due to the development, the use and protection of marine resources have not been scientifically, rationally and orderly laid out gradually, especially the unconventional over-exploitation of large-scale and single Chlamys farreri culture, which one-sidedly pursues the yield per mu and high output value of fish farming, making the waters The virtuous cycle chain of ecological balance is broken, resulting in the destruction of the diversity of marine biological resources and the imbalance of marine ecology; resulting in serious eutrophication of seawater in cultured sea areas, sharp reduction of plankton, and decrease of oxygen content per unit of water body year by year. Phenomena such as low meat rate, poor disease resistance and species degeneration have appeared one after another. In addition to the indiscriminate harvesting of bottom sea treasures, the output of some valuable sea treasures has gone from bad to worse.

[0004] At present, under the general environment of low-carbon economy, the ecological safety of mariculture has attracted more and more attention. Building a "submarine forest" in the ocean can not only create a good environment for sea treasures and fish that are bottom-sowed and raft cultured. Growing habitats, improving breeding benefits, and effectively purifying seawater, improving the deteriorating marine environment, and benefiting the reproduction of marine organisms. At present, the seabed forest is only a concept, and no one has yet realized it.
