Method for constructing integrated submarine forest

A forest and substrate technology, applied in the field of integrated submarine forest construction, can solve the problems such as the failure of scientific, rational and orderly layout of marine resource utilization and protection, the lack of proper grasp of laws, and the imbalance of marine ecology. Insufficient plants, reduced shellfish mortality, and the effect of preventing the floating of sediment

Problems solved by technology

[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

Example Embodiment

[0049] Example 1

[0050] The method for constructing an integrated submarine forest in this embodiment includes the following steps:

[0051] (1) Selection and transformation of submarine forest bottom quality

[0052] Submarine forest sediments are divided into 3 categories: (1) rocky sediments, (2) pebble sediments, and (3) sand and mud sediments. Choose different methods for submarine forest selection and transformation according to different sediments;

[0053] Pebble substrate: The pebble substrate is transformed by throwing stones or artificial algae reefs;

[0054] The pebble substrate is cast into artificial algae reef

[0055] (1) Construct an artificial algae reef, hoist the artificial algae reef to the ship with a crane, and pull the marking line with anchors and ropes in the reef casting area;

[0056] Artificial fishing reefs are made of reinforced concrete components, including a hollow reef body 1 with open ends. The walls 2 of each surface of the reef body (1) are provide...

Example Embodiment

[0070] Example 2

[0071] The method for constructing an integrated submarine forest in this embodiment is different from Embodiment 1:

[0072] (1) Selection and transformation of submarine forest bottom quality

[0073] To the bottom of the rock:

[0074] Most of the rock bottom does not need to be modified, only the artificial transplantation of macroalgae on the rocky reef without algae growth;

[0075] (2) Proliferation of large marine plants

[0076] Transplant large algae such as kelp and wakame on the algae-free rock bottom texture.

Example Embodiment

[0077] Example 3

[0078] The method for constructing an integrated submarine forest in this embodiment is different from Embodiment 1:

[0079] (1) Selection and transformation of submarine forest bottom quality

[0080] For sand and mud substrate:

[0081] A. Carry out reef-building by throwing rocks, reef-building with reinforced concrete components, and reef-building by shipwrecks for transformation;

[0082] B. Carry out artificial transplantation and cultivation of large leaf algae.

[0083] (2) Proliferation of large marine plants

[0084] For pebble geology and sandy mud bottom, after reef-building, use methods such as binding kelp seedling harvesters to transplant algae;

[0085] Artificial planting and transplanting of leaf algae on the bottom of sand and mud.

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. Due to the development, the utilization and protection of marine resources have not been laid out in a scientific, reasonable and orderly manner, especially the unconventional over-exploitation of large-scale and ...
