Description

Technical Field

[0001] The utility model relates to the technical field of marine ecological protection and restoration, in particular to a bioreef structure for transplanting seaweed. Background Art

[0002] Seagrass is the only angiosperm on Earth that can live entirely in seawater. Seagrass beds, along with mangroves and coral reefs, are considered one of Earth's three most iconic marine ecosystems. Seagrass beds are a key target for global marine ecosystem and biodiversity conservation, a vital indicator of a healthy marine environment, and a precious "undersea grassland" or "undersea forest." Seagrass beds have crucial ecological functions, including providing habitat and food sources for fisheries and rare species, purifying water and recycling nutrients, protecting embankments and mitigating disasters, and regulating climate.

[0003] However, the increasing disturbance of nearshore habitats by human activities (such as land reclamation, port construction, pollution, marine aquaculture, and dredging), coupled with natural factors such as global change, has led to widespread declines in seagrass beds, destabilizing benthic habitats and seriously threatening the survival of other marine life. Although seagrasses have a strong capacity for self-reproduction, the recovery of degraded seagrass ecosystems solely relying on self-colonization is slow. Therefore, seagrass bed restoration must be supplemented with effective human intervention to promote rapid establishment and ensure the healthy development of seagrass ecosystems. To date, coastal marine ecological conservation and restoration technologies have focused on single-species restoration, such as seagrass bed restoration, mangrove restoration, and oyster reef restoration, with few multi-habitat, multi-species restoration technologies. Multi-habitat approaches have been shown to enhance the resilience of restored sites to natural disturbances and accelerate natural succession processes beyond single-species restoration.

[0004] Therefore, it is necessary to provide a marine ecological restoration structure to create a variety of different marine habitats, provide a place for marine life to survive, rejuvenate and conserve marine life, repair the problem of offshore marine life degradation, and protect and improve marine biodiversity. Utility Model Content

[0005] The technical problem to be solved by the utility model is: in view of the above-mentioned problems, a bioreef structure for transplanting seaweed is provided.

[0006] The technical solution adopted by the utility model is: a bioreef structure for transplanting seaweed, characterized by comprising:

[0007] The bioreef unit has a triangular structure. The top surface of the bioreef unit is provided with a hollow frame, which is used to provide a growth space for seaweed and a cultivation and habitat environment for marine organisms. The bottom of the bioreef unit is provided with multiple through holes for tying seaweed rhizomes.

[0008] A seagrass bed is provided in the hollow frame, wherein the hollow frame is provided with planting covering soil capable of covering the rhizomes of the seagrass bed;

[0009] A stabilizing pile is provided at the bottom of the bioreef monomer and is used for being inserted into the seabed to stabilize the bioreef monomer.

[0010] Through the above technical means, a hollow frame is provided on the top of the bioreef unit, which can provide growth space for seaweed. At the same time, the hollow frame can facilitate the cultivation of marine life and provide a habitat for marine life, so that a multi-habitat habitat is created in the bioreef unit, thereby rejuvenating and conserving marine life.

[0011] In some embodiments, the seagrass bed uses lush and well-growing seagrass rhizome transplant units, and the seagrass rhizome transplant units use 2 to 3 plants per unit.

[0012] In some embodiments, the seagrass species of the seagrass bed are native dominant species, including salt-loving grass and eel grass.

[0013] In some embodiments, a plurality of the bioherm monomers can be spliced ​​together to form a bioherm unit.

[0014] In some embodiments, the bioreef monomer, the hollow frame and the stabilizing piles are all made of environmentally friendly, low-alkalinity, porous, and bio-adhesive marine ecological concrete.

[0015] In some embodiments, the planting covering soil is made of silty clay-fine sand mud.

[0016] Another technical solution adopted by the present invention is: a method for transplanting a bioreef structure of seaweed, characterized by comprising the following steps:

[0017] S1. Cultivation: Fresh seagrass rhizome transplant units are tied to the bottom through-holes of the bioreef units. Planting soil is filled into the bioreef units, ensuring that the planting soil completely covers the seagrass rhizomes at the bottom of the bioreef units and is compacted. The bioreef units are placed in offshore aquaculture areas for cultivation, and oyster seedlings are planted. Shellfish larvae are allowed to settle on the surface of the bioreef units, while the survival rate of the seagrass transplants is simultaneously restored.

[0018] S2. Deployment: Before the seagrass breeding season, mature bioreef units will be installed in the designated marine restoration area. During installation, the stabilizing piles at the bottom of the bioreef units will be driven into the seabed.

[0019] S3. Monitoring: Monitor before, during and after the launch.

[0020] Through the above-mentioned technical means, seagrass rhizome transplant units are laid in the hollow frame of the bioreef unit, so that the seagrass bed can have sufficient space for reproduction and growth, and the bioreef unit is placed in the offshore aquaculture area for cultivation, so that the bioreef unit can form a habitat for marine organisms such as oyster seedlings, thereby constructing habitats for multiple marine organisms and increasing the complexity of the ecosystem.

[0021] In some embodiments, in step S1, when the seaweed is covered with soil, 2 / 3 of the seaweed rhizomes are kept above the upper bottom surface of the bioreef unit, and the remaining 1 / 3 of the seaweed rhizomes are exposed to the lower bottom surface of the bioreef unit.

[0022] In some embodiments, in step S2, when installing the stabilizing piles, the bottom of the reef unit is ensured to be higher than the seabed surface to reserve a certain amount of settlement space.

[0023] In some embodiments, in step S3, the monitoring content includes water environment, sediment environment, and biological environment ecosystem health assessment.

[0024] The beneficial effects of the utility model are:

[0025] 1. The hollowed-out framework within the bioreef unit provides space for seagrass beds to grow and reproduce. The bioreef units are then placed in offshore aquaculture areas, allowing oysters and other marine organisms to attach to their surfaces. The hollowed-out framework simultaneously becomes a habitat for marine life. Compared to traditional single-species habitat restoration, this structure restores multiple marine habitats through multi-habitat construction, increasing the complexity of the ecosystem. The coexistence of multiple habitats can form a more stable and resilient ecosystem.

[0026] 2. By combining multiple reef units into a single reef unit, the overall structural stability is enhanced, dispersing wave energy and promoting the healthy development of biodiversity and ecosystems. Within the reef unit, the resulting oyster reef absorbs wave energy, stabilizes sediment, and promotes seagrass recovery. Seagrass beds not only provide habitat for a variety of organisms but also offer predation opportunities for oyster reefs. The roots of seagrass beds reduce suspended sediment, providing a stable substrate environment for oyster reefs and facilitating oyster attachment and growth. The decomposition of organic matter in seagrass beds provides nutrients for oyster reefs, promoting nutrient cycling within the ecosystem. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with specific embodiments.

[0034] Example 1:

[0035] Combine Figures 1 to 2 As shown, this embodiment is a bioreef structure for transplanting seaweed, including a bioreef unit 1, a hollow frame 2, a seaweed bed and a stabilizing pile 6. In this embodiment, the bioreef unit 1 is a triangular structure. The top surface of the bioreef unit 1 is provided with a hollow frame 2. The hollow frame 2 is provided with a seaweed bed and planting cover soil. The planting cover soil can cover the rhizomes of the seaweed bed. The hollow frame 2 is used to provide a growth space for seaweed and a cultivation and habitat environment for marine organisms. The bottom of the bioreef unit 1 is provided with a plurality of through holes 4, which are used to tie the rhizomes of seaweed. The bottom of the bioreef unit 1 is also provided with a stabilizing pile 6. The stabilizing pile 6 is inserted into the seabed to stabilize the bioreef unit 1.

[0036] Furthermore, the hollow frame 2 has a criss-cross hollow structure. On the one hand, the hollow frame 2 can provide horizontal and vertical growth space for the well-developed root system of seaweed. On the other hand, the hollow frame 2 can provide an attachment habitat for fixed and attached marine organisms such as oysters.

[0037] Furthermore, the stabilizing pile 6 is connected to the corner of the bottom of the bioreef unit 1. On the one hand, the stabilizing pile 6 is inserted into the seabed such as clay silt during use to stabilize the bioreef unit 1 and resist wind and wave erosion, and has a certain anti-subsidence burial and lateral displacement function for the overall structure. On the other hand, it is also convenient for modular splicing of different marine ecological restoration areas in the project.

[0038] In some implementations, the seagrass beds are constructed from lush, healthy seagrass rhizomes, with 2-3 plants per unit. The rhizomes are then washed in seawater to remove any sediment and other impurities. The seagrass species used in the seagrass beds are dominant native species near the project area, including salt-loving grass and eelgrass.

[0039] Furthermore, the through hole 4 provided at the bottom of the bioreef unit 1 can, on the one hand, stabilize the rhizomes of the seagrass to prevent tidal erosion, and on the other hand, provide a vertical growth environment for the fixation of the seagrass underground rhizomes, which is conducive to the rooting and fixation of seagrass transplanted plants and seedlings.

[0040] Furthermore, the planting covering soil adopts silty clay-fine sand mud to provide a growth substrate for the seaweed root system, and the reef unit 1, the hollow frame 2 and the stabilizing pile 6 all adopt environmentally friendly low-alkalinity, porous and easy-to-attach marine ecological concrete.

[0041] Furthermore, after the seaweed rhizomes are tied up with hemp ropes, fine sand, clay and water are evenly mixed with planting covering soil to form a mud blank which is then filled into the bioreef unit 1.

[0042] In some embodiments, as Figure 2 As shown, multiple bioherm units 1 can be spliced ​​together to form a bioherm unit. Specifically, in this embodiment, six bioherm units 1 can form a hexagonal bioherm unit. This not only increases the stability of the individual bioherm units 1, but also helps disperse wave energy, while promoting the healthy development of biodiversity and ecosystems.

[0043] Example 2:

[0044] This embodiment is a method for transplanting a bioreef structure of seaweed, comprising the following steps:

[0045] S1. Cultivation: Fresh seaweed rhizome transplant units transplanted within 1 to 2 days are tied to the bottom through-holes 4 of the bioreef unit 1, and planting cover soil is filled into the bioreef unit 1. The planting cover soil should completely cover the seaweed rhizomes at the bottom of the bioreef unit 1 and be compacted; the bioreef unit 1 is placed in an offshore aquaculture area for cultivation, oyster seedlings are added, and shellfish larvae are allowed to settle on the surface of the bioreef unit 1, while the survival rate of the seaweed transplants is simultaneously restored;

[0046] S1.1. When planting and covering seagrass with soil, keep 2 / 3 of the seagrass rhizomes above the upper bottom surface of the reef unit 1, and the remaining 1 / 3 of the seagrass rhizomes exposed to the lower bottom surface of the reef unit 1;

[0047] S2. Deployment: Before the seagrass breeding season, the mature bioreef units 1 are installed in the designated marine restoration area. During installation, the stabilizing piles 6 at the bottom of the bioreef units 1 are inserted into the seabed.

[0048] S2.1. When installing the stabilizing piles 6, ensure that the bottom of the bioreef unit 1 is slightly higher than the seabed to reserve a certain amount of settlement space;

[0049] S3. Monitoring: Monitoring before, during and after delivery;

[0050] S3.1. Monitoring contents include water environment, sediment environment, and biological environment ecosystem health assessment.

[0051] In this example, multiple marine habitats are restored through multi-habitat construction, increasing the complexity of the ecosystem. The coexistence of multiple habitats can form a more stable and resilient ecosystem. Seagrass and oyster reefs are interdependent and complementary in their ecological functions. Oyster reefs can purify seawater by filtering suspended particles in the water, increase seagrass photosynthesis, and contribute to the healthy growth of seagrass beds. Oyster reefs, through their complex three-dimensional structure, can reduce the impact of waves and protect seagrass beds from damage. Seagrass beds are also habitats for oysters and other filter-feeding animals. The biodiversity of oyster reefs attracts predators and foragers, forming a complex ecosystem. As restoration time increases, a healthy and biodiverse ecosystem gradually forms.

[0052] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
