[0036] The bank protection area 102 is stacked with a plurality of square-shaped concrete blocks 300, the concrete blocks 300 are formed with a plurality of holes, and the concrete blocks 300 are formed with habitat cavities 303 for aquatic animals to inhabit; the habitat cavities 303 penetrate the outer periphery of the concrete blocks 300 to form a plurality of side openings 302, the side openings 302 of adjacent concrete blocks 300 are aligned and communicated, and the habitat cavities 303 are provided with a cross-shaped elastic net 304; and the bank top area 103 is planted with a plurality of trees.

[0037] The above-provided artificial lake three-in-one original ecological restoration system has the following key technical advantages:

[0038] 1) By arranging the wire mesh cage 200 covered with the backfill soil layer in the lake bottom area 101 and filling the stone blocks 201 therein, the root system of the aquatic plants 202 can penetrate into the wire mesh cage 200 and grow in the backfill soil layer, which not only provides a stable growth environment for the aquatic plants 202, but also enhances the stability of the lake bottom, prevents disturbance and loss of the lake bottom silt, and promotes the growth and reproduction of the aquatic plants 202, thereby effectively absorbing the nutrients in the lake water, reducing the degree of eutrophication of the water body, and improving the water quality;

[0039] 2) The bank protection area 102 is stacked with the square-shaped concrete blocks 300, and the holes and habitat cavities 303 are arranged in the concrete blocks 300, the habitat cavities 303 penetrate the outer periphery of the concrete blocks 300 to form the side openings 302, and the side openings 302 of adjacent concrete blocks 300 are aligned and communicated, and the cross-shaped elastic net 304 is arranged in the habitat cavities 303, which provides a good habitat and breeding place for aquatic animals and algal species, increases the biodiversity, constructs a natural ecological environment, promotes the growth and reproduction of aquatic organisms, and is beneficial to restore and maintain the balance of the underwater ecosystem of the artificial lake 100;

[0040] 3) The bank top area 103 is planted with a plurality of trees, which further perfects the ecological system of the artificial lake 100 and improves the ecological stability of the entire region; through the synergistic effect of the aquatic plants 202, aquatic animals and algal species, the imbalance problem of the underwater ecosystem of the artificial lake 100 is solved, and the virtuous cycle and sustainable development of the ecological system of the artificial lake 100 are realized.

[0041] In the embodiment, the bottom of the wire mesh cage 200 is provided with a plurality of insertion bars 203, the insertion bars 203 are inserted into the lake bottom area 101 to fix the wire mesh cage 200 on the lake bottom area 101.

[0042] In this way, the displacement of the wire cage 200 caused by water flow impact or aquatic organism activity can be prevented, a stable growth foundation is provided for the aquatic plant 202, it is ensured that the root system of the aquatic plant 202 can smoothly penetrate the wire cage 200 and be planted into the backfill soil layer, thereby promoting the growth and reproduction of the aquatic plant 202, which is beneficial to the absorption of nutrients in the lake water, reduces the degree of water eutrophication, and further improves the water quality, thereby providing a basic guarantee for balancing the underwater ecosystem of the artificial lake 100.

[0043] In the embodiment, the top of the stake 203 is fixedly connected to the wire cage 200, the bottom of the stake 203 is inserted into the lake bottom area 101, and the stake 203 is arranged in a curved manner.

[0044] Through the curved arrangement of the stake 203, the contact area and friction with the lake bottom area 101 are increased, and the fixing effect of the wire cage 200 is further enhanced. Compared with the straight arrangement of the stake 203, the curved stake 203 can better adapt to the changes in the terrain of the lake bottom, and at the same time, when subjected to water flow or external force, it can more effectively disperse stress and reduce the risk of stake 203 breakage, thereby more reliably maintaining the stability of the wire cage 200.

[0045] In the embodiment, the bending directions of the plurality of stakes 203 are different; in this way, the wire cage 200 can obtain effective support and fixation in all directions, and the stability of the wire cage 200 under complex water flow conditions is enhanced. It can effectively resist water flow impact forces and forces generated by aquatic organism activity in different directions, thereby better maintaining the growth environment of the aquatic plant 202 and promoting its purification effect on the water body.

[0046] In the embodiment, the middle part of the wire cage 200 is provided with an elastically flexible plate 204 arranged transversely, the elastically flexible plate 204 is arranged in the same direction as the wire cage 200, and the elastically flexible plate 204 is wrapped in the backfill soil layer; the elastically flexible plate 204 is provided with a plurality of through holes penetrating upward and downward, and the root system of the aquatic plant 202 penetrates through the through holes.

[0047] By utilizing the elastic properties of the elastically flexible plate 204, the growth pressure of the root system of the aquatic plant 202 can be adapted, and as the root system grows and expands, the elastically flexible plate 204 can deform to a certain extent, so as to neither limit the growth of the root system nor provide a certain resistance to the root system, thereby promoting the root system to be more firmly anchored in the backfill soil layer, which helps to enhance the stability of the aquatic plant 202 and improve the absorption efficiency of nutrients in the water body, thereby more effectively reducing the degree of water eutrophication and improving the water quality.

[0048] In this embodiment, the elastic plate 204 is arranged in a multi-segment curved manner along the paving direction of the elastic plate 204; in this way, the elastic plate 204 can more evenly disperse the pressure generated by the root system growth of the aquatic plant 202, reduce local stress concentration, thereby reducing the risk of damage to the backfill soil layer structure by the root system, in addition, the curved elastic plate 204 can also guide the root system to grow in different directions, expand the distribution range of the root system, enhance the absorption capacity of the aquatic plant 202 to the nutrients in the water body, improve the water purification effect, and help maintain the balance of the underwater ecosystem of the artificial lake 100.

[0049] In this embodiment, the outer periphery of the stone block 201 is wrapped with an elastic net layer 205, a plurality of elastic protrusions 206 are protrudingly arranged on the elastic net layer 205, and the plurality of elastic protrusions 206 are arranged at intervals along the outer periphery of the stone block 201; the elastic protrusions 206 are embedded in the backfill soil layer and are in an elastic compression deformation state under pressure.

[0050] In this way, the plurality of elastic protrusions 206 on the elastic net layer 205 can elastically extrude the backfill soil layer, so that the backfill soil layer has elastic deformation performance, so that the root system of the aquatic plant 202 can better penetrate longitudinally and laterally.

[0051] In this embodiment, the artificial lake 100 is covered with a waterproof blanket 104, the waterproof blanket 104 is filled with sodium bentonite, the waterproof blanket 104 covers the lake bottom area 101, the revetment area 102 and the shore top area 103, the waterproof blanket 104 is covered with a covering soil layer 105, the wire mesh cage 200 is fixed on the covering soil layer 105, and the concrete block 300 is fixed on the covering soil layer 105.

[0052] Through the setting of the waterproof blanket 104, the soil loss and silt deposition of the lake bottom area 101, the revetment area 102 and the shore top area 103 are effectively prevented, the problems of water turbidity and lake bottom uplift caused by soil loss are avoided, and the sodium bentonite has good expansibility and water resistance, can form a dense waterproof layer, reduce the leakage of lake water, and maintain the stability of the lake water level;

[0053] At the same time, the covering soil layer 105 provides a stable fixing foundation for the wire mesh cage 200 and the concrete block 300, ensuring the structural stability of the entire original ecological restoration system, and the comprehensive protection and fixing measures help to maintain the overall ecological balance of the artificial lake 100, and create stable environmental conditions for the survival and reproduction of the aquatic plant 202, aquatic animals and algae species.

[0054] In this embodiment, the concrete block 300 is in a square shape, the habitat cavity 303 penetrates the outer periphery of the concrete block 300 to form four side openings 302, the habitat cavity 303 penetrates the top of the concrete block 300 to form a top opening 301, and the bottom of the habitat cavity 303 is arranged in a closed manner.

[0055] The four side openings 302 and the top opening 301 formed allow the organisms to enter and exit the habitat cavity 303 from multiple directions, increasing the activity range and habitat selection of the organisms, while the bottom closed habitat cavity 303 provides a relatively safe and stable shelter for the organisms, which is conducive to their habitat, reproduction and growth; in this way, the habitat of aquatic animal and macroalgae populations is increased, the biodiversity of the artificial lake 100 is improved, the food chain circulation of the underwater ecosystem is promoted, and the balance of the underwater ecosystem of the artificial lake 100 is restored and maintained.

[0056] In this embodiment, two elastic nets 304 divide the habitat cavity 303 into four adjacent sub-regions 305, and the four sub-regions 305 correspond to the four side openings 302, respectively; the elastic net 304 is attached with a bionic water grass 306.

[0057] The elastic net 304 divides the habitat cavity 303 into multiple sub-regions 305, increasing the complexity and diversity of the habitat cavity 303, wherein each sub-region 305 corresponds to a side opening 302, so that different types of aquatic animal and macroalgae populations can choose habitat regions according to their own preferences, improving the utilization efficiency of the habitat cavity 303.

[0058] The elastic net 304 also provides support points for organisms to climb and attach, increasing the activity space and survival opportunities of the organisms, and the bionic water grass 306 further simulates the natural ecological environment, providing a hiding place for the organisms and enhancing the ecological function of the habitat cavity 303.

[0059] Such design is conducive to attracting more aquatic organisms to inhabit and reproduce, enriching biodiversity and promoting the stability and balance of the underwater ecosystem, which plays a positive role in solving the imbalance of the underwater ecosystem of the artificial lake 100.

[0060] In the following, the technical solutions in the embodiments of the present application will be described in detail, clearly and completely, so that the content of the artificial lake trinity original ecological restoration system is easier to understand.

[0061] The artificial lake trinity original ecological restoration system comprises:

[0062] Based on the water ecological restoration theory, a full-biological solution scheme of the synergistic effect of macroalgae populations, aquatic plant communities and aquatic animal communities is adopted to construct a complete underwater biological chain, rebuild a healthy food chain ecosystem, realize natural conversion of nutrients in water, and replace algae with aquatic plants and animals as the dominant species in water.

[0063] The aquatic plants reduce the excess nutrients in the water by absorbing and oxidizing through photosynthesis, reduce the nutrient salt content in the water, and the aquatic animals (such as plankton, fish, shrimp, snail, shellfish, etc.) eat the aquatic plants, improve the eutrophication conversion ability, and maintain the water nutrient balance, which can restore the self-purification ability of the water body and the immunity to pollution, while consuming carbon dioxide, improving the environment, and achieving zero carbon and negative carbon effects.

[0064] The artificial lake three-in-one original ecological restoration system is mainly composed of a net algae biological population system, a water plant community system, and a water animal community system to form a complete ecological system, and realize water self-purification function. The net algae biological population is mainly composed of plankton specially domesticated and improved by a professional company. The water plants include improved four-season evergreen dwarf-type cattail, improved pollution-tolerant Asian giant spikerush, improved landscape Malayan pondweed, and improved landscape Hygrophila polysperma, etc. The water animals are composed of populations with original ecological habits bred by a professional company.

[0065] After the completion of the three-in-one original ecological restoration, the water quality can be maintained for a long time, the water body itself has self-purification function, the system can effectively prevent blue-green algae pollution and black odor phenomenon, the underwater landscape is full of vitality, the water bottom is covered with water grass, and fish and shrimp play in it, restoring natural and beautiful water scenery. At the same time, the system can also perfectly combine with the grassland in the land garden, highlight each other, and present the shore with green grass, the water with green grass, and the land with vitality.

[0066] The specific implementation method is as follows:

[0067] The first step: the net algae biological population feeds and digests the algae, organic particles and suspended solids in the water body, while producing weak acid excrement to inhibit the growth of algae in the water body.

[0068] The second step: as the algae and suspended solids in the water body decrease, the water transparency increases, the light enters the water bottom, and promotes the growth of submerged plants. The submerged plants can absorb a large amount of excess nitrogen and phosphorus and other nutrients in the water body, promote the nitrification / denitrification of nitrogen and the settlement of phosphorus, form an underwater forest, inhibit the resuspension of the bottom, and thus enhance the ecological self-purification ability of the water body.

[0069] The third step: after the water plants are restored, the net algae biological population carries beneficial microorganisms to the bottom of the water body, promotes the increase of the oxidation-reduction potential of the bottom mud, and is beneficial to the breeding of a large number of aquatic insects and aquatic benthic organisms. Under the symbiotic action of the water plants, the bottom mud nutrient material is stored and the ecological chain is self-purified. Then, the high-level aquatic animals such as snails, shellfish, fish and shrimp are introduced into the water body. The plankton and water plants can be eaten by high-level aquatic animals such as fish, shrimp, snail and shellfish, the nitrogen and phosphorus nutrients in the water body are transferred out through the food chain, the eutrophication degree of the water body is completely reduced, and the water quality of the landscape water body is maintained for a long time.

[0070] The water purification features of the artificial lake three-in-one original ecological restoration system are as follows:

[0071] 1. Significant water purification effect: the water quality is significantly improved, and the water body is free of blue-green algae and green algae pollution all year round, and is clear and transparent.

[0072] 2. Beautiful underwater landscape effect: the main aquatic plant varieties can achieve the effect of evergreen in four seasons, and other large submerged plant varieties can also successfully pass through winter and summer. The water body is clear and the water grass is lush, which is organically combined with the existing greenery, and reflects the harmonious coexistence of man and nature.

[0073] 3. Balanced and stable ecological system: perfect the underwater ecological system food chain to form a comprehensive, stable, scientific and healthy underwater ecological system. Through the double food chain of aquatic animals and aquatic plants, the excess nutrients such as nitrogen and phosphorus in the water body are transferred out, thereby completely reducing the degree of water body eutrophication and long-term maintaining the water quality of the landscape water body.

[0074] 4. Obvious ecological improvement effect on the surrounding environment: eliminate the hidden danger of releasing toxic and harmful gases from the original eutrophic water body; the healthy water ecological system can absorb and purify dust, nitrogen compounds and other substances in the air.

[0075] 5. Strong ecological health care effect: the photosynthesis of water grass increases the oxygen and negative ion content in the water body surrounding environment, which is beneficial to the health of tourists and residents. The water body surrounding environment forms a microclimate, which is cool in summer and warm in winter, and the air is filled with a pleasant fragrance, making people feel happy.

[0076] 6. Obvious energy-saving and environmental protection effect: the water quality of the landscape water body is long-term maintained in good condition, and the water is not replaced all year round. In summer, the water level can be maintained by rainwater, and in winter, the water level can be maintained by adding grey water. The system is self-repairing, which reduces maintenance costs and saves energy consumption.

[0077] 7. Can reduce and inhibit the breeding of mosquitoes and flies: the water is clear, the nutrient content of the water body is low, and a complete water body ecological food chain is formed, which effectively reduces and inhibits the breeding and reproduction of mosquitoes and flies.

[0078] 8. No biological side effects and no secondary pollution: the net algae biological population is at the bottom of the food chain, and there is no biological safety problem. Through the energy transfer mode of the biological chain, the nutrient salts in the water are enriched on higher plants and animals, realizing the benign circulation and self-purification of the ecological system, and there is no secondary pollution.

[0079] The maintenance technology content of the artificial lake three-in-one original ecological restoration system is as follows:
