Preferably, reed, loosestrife, pampas grass, calamus, water plantain, canna, cyperus, and foxtail are planted in the emergent plant area 44 at the same time.

[0046] For example, 9 pots of plants can be planted in the emergent plant area 44, and the diameter of the planting hole is 16 cm. In order to facilitate the activities and foraging of water birds, the artificial floating islands in the emergent plant area 44 are laid according to the principle of laying 2 rows and leaving 1 row empty. The plant coverage rate in the shallow water area is 60-80%.

[0047] The emergent plant area 44 can be formed by splicing high-density polyethylene or composite fiber artificial floating islands, and the outer contour of the artificial bird island is arranged in a wavy shape, which can increase the perimeter area ratio and aesthetics of the artificial bird island.

[0048] The bottom of the mud and gravel beach area 41 is made of solid buoyancy material and is connected to the frame 1 structure. The bottom is paved with sand and gravel with a thickness of 3 to 5 cm and a particle size of 1.5 mm to 2.5 mm.

[0049] In order to facilitate bird habitat, bird nests and / or bird habitats are provided in the shrub area 43 and / or the emergent plant area 44. Preferably, bird nests and bird habitats are provided in the shrub area 43 and the emergent plant area 44 at the same time.

[0053] In order to facilitate the fish to inhabit, fish nests are arranged on the fish and aquatic organism inhabiting layer 3. The fish nests include chain fish nests 32 and / or bottom sinking fish nests.

[0054] There are multiple chain fish nests 32, which are fixed on the frame 1 through steel wires 321. The distance between two adjacent chain fish nests 32 is greater than or equal to 50 cm.

[0055] The bottom sinking fish nest is placed below the chain fish nest 32. The bottom sinking fish nest is a hard bottom sinking fish nest, which is supported by the main structure of the frame 1 and placed below the chain fish nest 32.

[0056] Among them, the bottom type fish nest can be made of a combination of branches, gravel, and fish nest bricks.

[0057] In order to facilitate the habitat of other organisms, a biological habitat 31 can be set on the fish and aquatic organism habitat layer 3. The biological habitat 31 can be made of dead wood, bamboo poles, wooden stakes, etc., which are fixed on the frame 1.

[0058] The four corners at the bottom of the main frame are provided with lifting ears, and the four corners at the top are provided with through openings for clamping the lifting ears.

[0059] The horizontal specifications of frame 1 are preferably 2m*2m or 3m*3m, and the size of the wood strips of frame 1 is preferably 80×80 mm or 100×100 mm. The connection nodes of frame 1 are connected by vertical wood, and the nodes of frame 1 are connected by mortise and tenon joints or bolts. The height of frame 1 is 1-1.5m, which can be determined by the depth of the water body.

[0060] Specifically, the connection structure realizes the detachable connection of two adjacent frames in the horizontal direction, and there are many ways to achieve it, such as using steel wire binding. However, it is not easy to disassemble and assemble.

[0061] In order to facilitate disassembly and assembly, the following structure can be adopted:

[0062] Reference Figure 3-6 The connection structure includes a connection member 14, a connection tube 15, a connection cap 16 and a locking member 17. The connection tube 15 includes a fixing column 153 and a plurality of arc plates 151 fixed on the fixing column 153 for covering two connection members 14, and the arc plates 151 are provided with a first fixing hole 152; the connection cap 16 is provided with a second fixing hole corresponding to the first fixing hole 152; the locking member 17 is used to connect the first fixing hole 152 and the second fixing hole to lock the connection tube 15 and the connection cap 16.

[0063] In order to facilitate the connection of the connecting tube to the two connecting members 14, for example, Figure 6 As shown, one side of the connecting member 14 is a plane to achieve the splicing of two connecting members; and a groove is provided on the connecting member, and the groove is used to insert the arc plate 151.

[0064] Using the above structure, Figure 3 , 4 As shown, a connecting member 14 is fixed to each corner of the frame. When the frame is to be expanded, the connecting members 14 of the two frames are put together in a flat surface, as shown in FIG. Figure 6 After the arc plate 151 of the connecting tube 15 is inserted outside the two connecting pieces 14 so that the arc plate wraps the two connecting pieces 14, one end of the connecting cap 16 is placed on the arc plate 151, and the locking piece 17 is inserted into the first fixing hole 152 and the second fixing hole to lock the connecting tube 15 and the connecting cap 16, thus realizing the extended connection of the two frames.

[0065] In order to improve the stability of the connection, the arc plate 151 needs to have a certain hardness to prevent the connecting piece from falling out of the gap between the two arc plates 151 when the frame is subjected to force.

[0066] In order to further improve the connection stability, a locking structure can be provided on the connector to achieve the locking of the two connectors. Specifically, a protrusion with a T-shaped cross section is provided on one side of a connector 14 that is flat, and a groove with a T-shaped cross section is provided on one side of the other connector 14 that is flat. With this structure, the two connectors can be locked in the radial direction, while the connecting tube 15, the connecting cap 16 and the locking member 17 are locked in the axial direction, reducing the requirements on the performance of the connecting tube 15, the connecting cap 16 and the locking member 17.

[0067] In order to achieve the expansion of the upper and lower frameworks, such as Figure 3 As shown, the main frame 11 can be provided with hanging ears 13 at the bottom four corners and through openings 18 at the top four corners. When splicing, the hanging ears 13 of the upper frame are inserted into the through openings 18 of the lower frame, and then the pins 17 are used to fix the upper and lower frames 1 to achieve splicing.

[0068] The lifting lug 13 can also serve as a connection portion for the anchor structure 5 , avoiding the need to develop a connection component on the frame 1 .

[0069] The artificial bird island constructed by splicing the frame 1 and the anchoring structure in this solution has a simple and stable structure, convenient construction, low cost, strong adaptability, and is suitable for development and application in urban water bodies. At the same time, the environmental configuration of the present invention enriches the ecosystem of the artificial bird island, and compared with the existing technology, it can purify urban water bodies and provide a better reproduction and survival basis for aquatic organisms and birds.

[0070] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
