Description

Technical Field

[0001] The invention relates to the field of wetland protection, and in particular to a hollow brick and a wetland matrix block for promoting the protection and restoration of aquatic plant diversity. Background Art

[0002] With the continuous improvement of urbanization and industrialization, most wetlands have shown a trend of increasing fragmentation. At the same time, the core area of ​​wetlands has also dropped sharply, the migration of organisms has been blocked, and the ecological function of wetlands has continued to decline. The importance of wetlands has been recognized by more and more countries and organizations, and many wetland restoration projects have been launched around the world.

[0003] Artificial wetlands can remove water pollutants and provide habitats for wild animals and plants. They are widely used in water purification and ecological restoration. As an important component of wetland ecosystems, aquatic plants not only have important landscape value, but also play an important role in maintaining the integrity of the entire wetland ecosystem. In the early stages of wetland ecological restoration, aquatic plants have not yet reached a certain biomass, the community structure is imperfect, and the stability is poor. Therefore, in the early stages of the restoration project, the feeding of the roots and stems of aquatic plants by birds of the seed-eating group and the tuber-eating group will have a serious negative impact on the aquatic plant community and the entire wetland ecosystem.

[0004] In order to reduce the risk of birds eating the roots and stems of aquatic plants, measures have been taken, including: regulating water levels, setting up ground physical barriers to prevent birds from entering certain vulnerable areas, and artificially supplementing bird food sources. Among them, water level regulation has high costs and technical requirements, does not conform to natural hydrological dynamics, and has water resource shortages. The setting of ground physical barriers may affect the beauty of natural landscapes, have limited protective effects, and hinder the activities of other organisms. Artificial supplementation of bird food is difficult to implement in the long term, and the long-term maintenance cost is high, which will cause an imbalance in the food chain. Summary of the invention

[0005] The present invention can solve the problem in the prior art that the roots and stems of aquatic plants are eaten by birds, affecting the restoration of wetland ecosystems, by providing a hollow brick and a wetland matrix block that promote the protection and restoration of aquatic plant diversity.

[0030] Example 1

[0031] The present invention discloses a hollow brick for promoting the protection and restoration of aquatic plant diversity. The hollow brick 10 is made of permeable concrete and has the characteristics of firm structure, high strength, good water permeability and eco-friendliness.

[0032] Specifically, the hollow brick 10 is a cubic structure, the side length of which is 60 to 80 cm, and the height of which is not lower than the lowest water level of the wetland in the dry season. The hollow brick 10 has a hollow cavity inside, the bottom of which is an open structure, and the thickness of the side wall and the upper wall is 3 to 5 cm. In this embodiment, the side length of the hollow brick 10 is 60 cm and the thickness is 5 cm.

[0033] The four side walls of the hollow brick 10 are respectively provided with rectangular opening grooves 11, and the opening grooves 11 are connected to the hollow cavity of the hollow brick 10. The opening direction of the opening groove 11 is downward, and its width is 1 / 2 to 4 / 5 of the width of the side wall, and its height is 1 / 2 to 4 / 5 of the height of the side wall. In this embodiment, the width of the opening groove is 50 cm and the height is 55 cm. The design of the opening groove 11 and its connection with the hollow cavity of the hollow brick 10 ensures that the brick body does not hinder the flow of water and the activity of aquatic plants.

[0034] The upper wall surface of the hollow brick 10 is provided with evenly arranged holes 12 , and the holes 12 can be communicated with the hollow cavity of the hollow brick 10 .

[0035] Specifically, the holes are circular holes with a diameter of 2 to 3 cm and a hole spacing of 2 to 3 cm. In this embodiment, the hole diameter is 3 cm and the hole spacing is 2 cm. The depth is the thickness of the upper wall of the hollow brick 10, 5 cm.

[0036] The design of the hole 12 can effectively prevent water birds from feeding on the roots, stems and seeds of aquatic plants in the wetland sediments without affecting the natural growth of the aquatic plants. The aquatic plants that have recovered can grow naturally through the hole 12.

[0037] Rectangular grooves 13 are symmetrically distributed along the edge of the upper wall of the hollow brick 10, and the rectangular grooves 13 are connected to the hollow cavity of the hollow brick 10. And the rectangular grooves 13 of any two hollow bricks 10 can be combined into a rectangular notch.

[0038] Specifically, the side length of the rectangular groove 13 is 8-10 cm. In this embodiment, the side length is 8 cm.

[0039] The design of the rectangular groove facilitates the connection and fixation of adjacent hollow bricks through the connecting blocks after the hollow bricks are assembled, and also facilitates the fixation of the hollow bricks to the wetland.

[0040] In addition, the surface of the upper wall of the hollow brick 10 is polished to form an uneven concave-convex surface, which can increase the surface area for microorganisms to attach, thereby promoting the formation of biofilms, further improving the purification capacity of water bodies, and having a certain anti-slip function.

[0041] The hollow structure of the hollow bricks and the structural design of the circular holes on their upper walls provide habitats for microorganisms and invertebrates, thereby promoting the diversity of the wetland ecosystem and maintaining the natural hydrological cycle of the wetland.

[0042] Example 2

[0043] The present invention discloses a wetland matrix block for promoting the protection and restoration of aquatic plant diversity, comprising the hollow brick 10 and the connecting block 20 in embodiment 1.

[0044] Specifically, a plurality of hollow bricks 10 are arranged closely in sequence with one side having the rectangular groove 13 to form a hollow brick row.

[0045] Multiple rows of hollow bricks are closely arranged with their sides close to each other to form a hollow brick array.

[0046] The number of hollow bricks 10 in a hollow brick row and the number of hollow brick rows are determined according to the area of ​​the wetland.

[0047] Specifically, in the same hollow brick row, the rectangular grooves 13 of any two adjacent hollow bricks 10 are combined to form a rectangular notch 30, and the connecting block 20 is installed in the rectangular notch 30 to connect the adjacent hollow bricks 10 to increase stability.

[0048] The connection block 20 is a rectangular parallelepiped structure, and its size is the same as that of the rectangular notch 30. In this embodiment, the connection block 20 has a thickness of 5 cm, a length of 16 cm, and a width of 8 cm.

[0049] In addition, in order to further increase the stability of the wetland matrix block in the wetland, positioning piles (not shown) can be installed in the rectangular grooves 13 at both ends of the hollow brick row. The bottom ends of the positioning piles can penetrate into the bottom mud of the wetland, effectively increasing the stability of the entire matrix block.

[0050] The wetland matrix block of the present invention provides a habitat for microorganisms and invertebrates through the structural design of hollow bricks, thereby promoting the diversity of the wetland ecosystem and maintaining the natural hydrological cycle of the wetland. The hollow bricks that can be spliced ​​and disassembled are used as modules to facilitate the maintenance and replacement of the wetland matrix block.

[0051] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention.
