Description

Technical Field

[0001] The present invention relates to the technical field of mangrove planting-aquaculture coupling, and particularly relates to a simulation platform and method for a mangrove planting and breeding coupling mode. Background Art

[0002] Mangroves are wetland woody plant communities composed of evergreen trees or shrubs growing in the intertidal zones of tropical and subtropical coasts. They play an important role in purifying seawater, preventing wind and reducing disasters, carbon sequestration and storage, and maintaining biodiversity. They are also the habitats and breeding grounds for economic organisms such as fish, shrimps, crabs, and shellfish, and have important ecological and economic values.

[0003] Mangrove plants have a purification effect on pollutants such as excessive N, P, and heavy metals in water bodies, and can reduce the occurrence of aquaculture diseases. There are many types of mangrove plants, and different types of mangrove plants have different purification effects. Mangrove plants can provide nutritional support for symbiotic economic animals. The better the coupling symbiosis adaptability between mangrove plants and economic animals, the greater the nutritional support provided. At the same time, the decomposition of mangrove plant litter consumes dissolved oxygen in the water body, which will deteriorate the water environment and affect the growth of economic animals. The purification effect of mangrove plants on water bodies and the nutritional support function for symbiotic economic animals can improve the living environment of economic animals and promote the growth of economic animals. Since the ecological effects and economic values of different mangrove planting-aquaculture coupling modes are different, current research mainly constructs mangrove planting-aquaculture coupling systems in natural tidal flat areas, and obtains the key technical parameters of the planting and breeding coupling mode through on-site experiments. However, constructing a mangrove planting-aquaculture coupling system in natural tidal flat waters has high construction intensity and difficulty, huge costs, a long cycle, and the planting work of mangroves still needs to be completed manually, which is time-consuming and laborious. Therefore, it is necessary to provide an accurate and efficient simulation platform for mangrove planting and breeding coupling modes to solve the above problems, provide key parameters for constructing the optimal mangrove planting and breeding coupling mode, and explore a win-win path for mangrove cultivation and aquaculture.

[0045] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0046] As Figure 1 shown, the first aspect of the present invention provides a simulation platform for a mangrove aquaculture-coupled cultivation mode. The simulation platform for a mangrove aquaculture-coupled cultivation mode includes an aquaculture-coupled mechanism and a planting assistance mechanism.

[0047] As Figure 1 、 2 、3 shown, the aquaculture-coupled mechanism includes a first cylinder 101. The first cylinder 101 is cylindrical. An inlet and outlet are provided on the side surface of the first cylinder 101. A first opening and closing door 102 is installed at the inlet and outlet through a hinge. A water guide pipe 103 is connected to the first cylinder 101. A timing flow solenoid valve 104 is installed on the water guide pipe 103, and the water guide pipe 103 is connected to a water supply system. A second cylinder 105 is embedded in the first cylinder 101.

[0048] As Figure 1 、 2 、3 shown, the second cylinder 105 is cylindrical. The second cylinder 105 is provided with the same inlet and outlet. A second opening and closing door 203 is installed at the inlet and outlet through a hinge. And a planting assistance mechanism is provided above the second cylinder 105.

[0049] As Figure 1 、 2 、3 shown, the inner bottom of the first cylinder 101 is paved with a first intertidal zone bottom mud 108. The inner bottom of the second cylinder 203 is paved with a second intertidal zone bottom mud 109, and the laying height of the second intertidal zone bottom mud 109 is higher than the laying height of the first intertidal zone bottom mud 108.

[0050] As Figure 1 、 2As shown in Figs. 2 and 3, a plurality of oyster racks 201 are placed on the first intertidal mud 108. The second intertidal mud 109 can be used for planting mangrove seedlings, and natural reefs 202 are arranged on the second intertidal mud.

[0051] As Figure 1 , 2 , 3, a stainless steel mesh 204 is wound around the outside of the second opening and closing door 203, and a door handle 205 is arranged on the second opening and closing door 203. The second opening and closing door 203 can be opened inside the first cylinder body 101.

[0052] It should be noted that before starting to simulate the mangrove planting and aquaculture coupling system, the operator can enter the inside of the first cylinder body 101 by opening the first opening and closing door 102 and put benthic clams 601, benthic sipunculids 508, fish 505, shrimp 506 and crabs 507 on the first intertidal mud 108. At the same time, several oysters 509 are hung on the oyster racks 201. Then the operator opens the second opening and closing door 203 through the door handle 205 to enter the inside of the second cylinder body 105, and puts some benthic clams 601, benthic sipunculids 508 and crabs 507 on the second intertidal mud 109, and places some oysters 509 on the natural reefs 202 to complete the task of putting the aquaculture organisms for simulating the mangrove planting and breeding coupling mode. According to different mangrove planting simulation requirements, the aquaculture organisms can be freely combined for putting to explore and discover the diversity of the coupling modes between different mangrove planting schemes and different aquaculture organisms. At the same time, the first cylinder body 101 can be designed with corresponding diameter and height according to the actual simulation needs, can be built indoors, has the advantages of easy material collection, simple assembly and small volume, is easy to disassemble and migrate, meets the simulation conditions in most scenario environments, and provides key parameters for the design of the mangrove planting and breeding coupling scheme.

[0053] It should be noted that after the aquaculture organisms are placed, the operator needs to close the first opening and closing door 102 and the second opening and closing door 203 one by one and leave the simulation platform. At this time, according to different mangrove planting and breeding coupling simulation schemes, the predetermined mangrove seedlings 504 are placed on the planting auxiliary mechanism, and the planting auxiliary mechanism is controlled to automatically plant the mangrove seedlings 504 into the second intertidal mud 109 at the bottom of the second cylinder body 105, so as to quickly assist in planting different mangrove seedlings in the mangrove planting and breeding coupling ecological effect simulation platform and save the labor output cost; among them, in order to simulate the situation that the mud in the mangrove growth area in the natural tidal flat sea area is higher than that in the area without mangroves, the laying height of the second intertidal mud 109 should be higher than that of the first intertidal mud 108. This design also ensures that the bottom end of the second opening and closing door 203 will not damage the integrity of the first intertidal mud 108 when it is opened inside the first cylinder body 101, and improves the use compatibility of the second cylinder body 105 inside the first cylinder body 101.

[0054] As Figure 1 , 2 shown in Fig. 3, the first cylinder block 101 is made of transparent tempered glass. A water quality automatic tester 106 is arranged inside the first cylinder block 101. A temperature regulator 107 is installed inside the first cylinder block 101. An air inflation device 602 is arranged on the side of the first cylinder block. The air inflation pipe of the air inflation device 602 extends to the inside of the first cylinder block.

[0055] It should be noted that when simulating different mangrove planting and aquaculture coupling systems, after releasing the cultured organisms and mangrove seedlings, the presetting of the water inlet and outlet time and the water inlet and outlet volume is completed by adjusting the timing flow solenoid valve 104 to simulate the tidal law of the natural tidal flat sea area. When the preset water inlet and outlet time is reached, the timing flow solenoid valve 104 will open, so that the flood system injects natural seawater 503 into the inside of the first cylinder block 101 through the water conduit 103 until the injected natural seawater 503 submerges the roots of the released cultured organisms and mangrove seedlings 504. And when the high tide water level line 603 or the low tide water level line 604 is reached, the timing flow solenoid valve 104 is controlled to close and the water supply action stops. At this time, the seawater injected into the first cylinder block 101 will enter the second cylinder block 105 through the stainless steel mesh 204, realizing the connectivity and coupling of the aquaculture environments of the first cylinder block 101 and the second cylinder block 105, and further improving the reliability of the simulation parameters of the aquaculture coupling system.

[0056] It should be noted that the water quality parameter automatic tester 106 can monitor environmental parameters such as the temperature, salinity, pH, and dissolved oxygen of the water body in real time. In the natural tidal flat sea area, the temperature of the seawater at different times usually varies under sunlight irradiation. Therefore, in order to more truly restore the temperature of the mangrove planting area in the tidal flat sea area, the temperature regulator 107 is controlled to adjust the temperature of the injected natural seawater 503 by simulating the natural environment temperature. And at the same time, the air inflation device 602 is controlled to start injecting gas into the natural seawater 503 to make it more conform to the underwater environment of the natural tidal flat sea area, so as to ensure the simulation accuracy of the mangrove planting-aquaculture coupling mode simulation platform. After the simulation is completed, the water quality of the seawater in the first cylinder block 101 and the second cylinder block 105 is synchronously detected by the water quality automatic tester 106 to obtain the detection data of the seawater quality after simulation in real time. By further analyzing the detection data of the seawater quality, the purification effect of different mangrove planting schemes on the natural tidal flat aquaculture water body can be evaluated, thereby providing key parameters for the design of the mangrove aquaculture coupling scheme.

[0057] As Figure 4As shown, the planting assistance mechanism includes a movable support frame 206, a universal caster 207 is installed at the bottom of the movable support frame 206, a cross beam 208 is arranged on the movable support frame 206, and a first planting module 209 is welded on the cross beam 208.

[0058] As Figure 4 , 5 , 6 shows, the first planting module 209 includes two symmetrically arranged L-shaped fixing strips 301, a guide rail frame 302 is connected between the two L-shaped fixing strips 301, a guide rail column 303 penetrates through the middle of the guide rail frame 302, two first bearing brackets 304 are fixed at the rear end of the guide rail column 303, the two first bearing brackets 304 penetrate through a ball screw 305 at the same time, a ball screw guide block 306 is connected to the ball screw 305, the ball screw guide block 306 is fixed on the side surface of the guide rail frame 302, and one end of the ball screw 305 is connected to a first servo motor 307 through a coupling.

[0059] It should be noted that when the first servo motor 307 is controlled to start, the first servo motor 307 drives the ball screw 305 to rotate. Since the guide rail frame 302 is fixed to the cross beam 208 through two L-shaped fixing bars 301, and the ball screw guide block 306 is fixed to the side of the guide rail frame 302, the rotation of the ball screw 305 will cause the ball screw 305 to make a gradually descending rotational movement on the ball screw guide block 306. Therefore, the guide rail column 303 is driven to make a relative vertical descending movement in the guide rail frame 302. The vertical descending movement of the guide rail column 303 will drive the entire second planting module 308 to descend according to the ideal height where the mangrove seedlings 504 are placed by the operator. At this time, the operator can further control the second planting module 308 to open and place one or more mangrove seedlings 504 to be planted into the second planting module 308, realizing the preparation before the planting of the mangrove seedlings 504. After the placement is completed, the first servo motor 307 is controlled to reverse. The reverse rotation of the first servo motor 307 causes the ball screw 305 to rotate synchronously in the reverse direction, so that the ball screw 305 makes a gradually ascending rotational movement on the ball screw guide block 306. Therefore, the guide rail column 303 is driven to make a relative vertical ascending movement in the guide rail frame 302, thereby driving the entire second planting module 308 to rise until it is higher than the height of the second cylinder 105. At this time, the planting auxiliary mechanism is placed on one side of the second cylinder 105 by pushing the movable support frame 206, and the position of the movable support frame 206 is adjusted through the universal casters 207 so that the second planting module 308 is aligned with the predetermined mangrove planting position. At this time, the first servo motor 307 is controlled to rotate forward again. Similarly, the guide rail column 303 is driven to make a relative vertical descending movement in the guide rail frame 302, so that the guide rail column 303 continuously descends in the second cylinder 105 until the first servo motor 307 stops running after driving the second planting module 308 to reach the appropriate planting height, realizing the purpose of automatically transporting the mangrove seedlings 504 into the second cylinder 105, replacing the labor steps of manually transporting the mangrove seedlings 504 in and out of the second cylinder 105 multiple times by hand, saving time and effort, greatly improving the planting rate of the mangrove seedlings 504, and being able to transport various different quantities of mangrove seedlings 504 according to requirements, solving the transportation problem that it is difficult for traditional manpower to carry multiple mangrove seedlings 504, improving the planting quality of the mangrove seedlings 504, and ensuring the simulation accuracy of the mangrove planting and breeding coupling mode simulation platform.

[0060] Such as Figure 5 、 7As shown in Figures 7 and 8, a second planting module 308 is fixed to the front end of the guide rail column 303 through a connecting bar. The second planting module 308 includes a driving plate 309. Two second bearing brackets 401 are arranged on the driving plate 309. A left - right threaded rod 402 is fixed to the two second bearing brackets 401. One end of the left - right threaded rod 403 is connected to a second servo motor 403 through a coupling. Each of the left - hand and right - hand threads on the left - right threaded rod 402 is connected to a nut guide block 404.

[0061] As Figure 5 , 7 As shown in Figures 7, 8, one end of a U - shaped connecting rod 405 is hinged to the outside of one of the nut guide blocks 404. The other end of the U - shaped connecting rod 405 is hinged to one end of a Y - shaped connecting rod 406. The other end of the Y - shaped connecting rod 406 is hinged to the outside of the other nut guide block 404. And an arc - shaped object - topping groove 407 is connected to the hinged part of the U - shaped connecting rod 405 and the Y - shaped connecting rod 406.

[0062] As Figure 5 , 7 As shown in Figures 7, 8, a dredging plate 408 is welded to the bottom of each nut guide block 404. And the two dredging plates 408 are symmetrically distributed. A dredging shovel 409 is arranged at the bottom of each dredging plate 408. A mud - spreading shovel 501 is fixed to the side of the dredging shovel 409. A distance sensor is arranged at the bottom of the dredging plate 408. An underwater vision camera 502 is installed on the side of the dredging plate 408.

[0063] It should be noted that when the second servo motor 403 is controlled to rotate forward, the second servo motor 403 will drive the left - right threaded rod 402 to rotate forward. When the left - right threaded rod 402 rotates forward, it will drive the nut guide blocks 404 connected to the left - right threads respectively to move towards both ends of the left - right threaded rod 402, so that the two nut guide blocks 404 make a relative separation movement. During the relative separation movement of the two nut guide blocks 404, they will synchronously drive the U - shaped connecting rod 405 and the Y - shaped connecting rod 406 to move towards both ends of the left - right threaded rod 402 respectively. Therefore, the included angle between the U - shaped connecting rod 405 and the Y - shaped connecting rod 406 will gradually increase to achieve an opening trend. When an opening trend is formed, the hinge point of the U - shaped connecting rod 405 and the Y - shaped connecting rod 406 will gradually move backward, so that the arc - top object groove 407 will gradually move backward synchronously. At this time, a certain object - clamping space is formed between the arc - top object groove 407 and the two dredging plates 408, and the operator can place the mangrove seedlings 504 in this object - clamping space; after the placement is completed, control the second servo motor 403 to reverse to drive the left - right threaded rod 402 to rotate in the reverse direction. When the left - right threaded rod 402 rotates in the reverse direction, it will drive the nut guide blocks 404 connected to the left - right threads respectively to move towards the middle part of the left - right threaded rod 402, so that the two nut guide blocks 404 make an opposite converging movement, and then gradually reduce the included angle between the U - shaped connecting rod 405 and the Y - shaped connecting rod 406 to form a closing trend, which can drive the arc - top object groove 407 to gradually move forward, so that the arc - top object groove 407 clamps the placed mangrove seedlings 504 by pushing against the object. The placement, clamping and fixing effect before the planting and transportation of the mangrove seedlings 504 is realized, replacing the traditional manual handling process of the mangrove seedlings 504, saving labor, and playing an auxiliary role in the accurate positioning and placing of the subsequent mangrove seedlings 504 in the second cylinder body 105, improving the planting quality of the mangrove seedlings 504, avoiding the dropping or damage of the mangrove seedlings 504 caused by shaking and vibration during the transportation to the second cylinder body, ensuring the integrity of the mangrove seedlings 504, reducing the replacement cost of the mangrove seedlings 504, and having high economic benefits and reliability.

[0064] It should be noted that the distance sensor needs to preset a distance threshold between the dredging shovel 409 and the second intertidal zone sediment 109 when the dredging shovel 409 is inserted into the second intertidal zone sediment 109; when the first planting module 209 drives the second planting module 308 to vertically descend in the natural seawater 503 of the second cylinder body 105, the distance sensor and the underwater vision camera 502 are turned on at this time. The underwater vision camera 502 will synchronously capture an image of the second intertidal zone sediment 109 at the optimal planting height and transmit the image to the operating system, enabling the operator to judge whether the second planting module 308 deviates from the ideal planting area, so as to facilitate the operator to adjust the position of the movable support frame 206 so that the second planting module 308 is directly below the ideal planting area; the distance sensor will detect the distance information between it and the second intertidal zone sediment 109. If the detected distance information is less than or equal to the preset distance threshold, it means that the dredging shovel 409 has contacted and inserted into the second intertidal zone sediment 109. At this time, the first servo motor 307 will be controlled to stop working; when the dredging shovel 409 is inserted into the second intertidal zone sediment 109, the second servo motor 403 can be controlled to rotate forward at this time, so that the two nut guides 404 make a relative separation movement. When the two nut guides 404 make a relative separation movement, they will drive the two dredging plates 408 to synchronously make a relative separation movement. The relative separation movement of the two dredging plates 408 will drive the dredging shovel 409 to dig the second intertidal zone sediment 109 in the ideal planting area to both sides to form a planting hole of appropriate size. And when the two nut guides 404 make a relative separation movement, the arc top object groove 407 will move backward at the same time. At this time, the mangrove seedlings 504 will pass through the gap between the two dredging plates 408 and fall into the dug planting hole, realizing the actions of automatically digging a hole and automatically putting the mangrove seedlings 504 into the planting hole; after the mangrove seedlings 504 are put into the dug planting hole, since the second intertidal zone sediment 109 will accumulate on the side of the dredging shovel 409 when the dredging shovel 409 dredges to both sides and is placed between the dredging shovel 409 and the mud spreading shovel 501, controlling the second servo motor 403 to reverse, so that the two nut guides 404 make an opposite converging movement, can make the two dredging plates 408 synchronously make an opposite converging movement. At this time, the mud spreading shovel 501 will aggregate and spread the second intertidal zone sediment 109 accumulated on one side of the dredging shovel 409 into the planting hole where the mangrove seedlings 504 have been previously placed, realizing the mud filling action effect of planting the mangrove seedlings 504; through this process, it is possible to replace the cumbersome steps and labor output of manually putting the mangrove seedlings 504 and manually digging and filling the mud, saving time and effort, improving the planting rate and quality of the mangrove seedlings 504, and at the same time being able to adjust the planting position of the mangrove seedlings 504 to explore the coupling and symbiotic effects of different mangrove seedling 504 planting patterns on aquaculture organisms in a diverse manner, realizing the intelligent automation of the mangrove planting and breeding coupling simulation system, with high practicality.

[0065] The second aspect of the present invention provides a method for using a simulation platform for the ecological effects of mangrove cultivation and aquaculture, which is applied to any one of the simulation platforms for the ecological effects of mangrove cultivation and aquaculture, and specifically includes the following steps:

[0066] Obtain the tidal law parameters and environmental parameters of the natural tidal flat sea area within a preset time period, simulate the natural tidal law and environmental parameters, and put different aquaculture organisms into the mangrove cultivation and aquaculture simulation platform for simulation cultivation and aquaculture in the cases of no mangrove planting, single-species mangrove planting, and mixed planting of multiple mangroves;

[0067] During the simulation cultivation and aquaculture process, regularly detect the growth conditions of each aquaculture organism, and obtain the growth parameters of each aquaculture organism under different mangrove planting conditions; wherein, the different aquaculture organisms include fish, shrimps, crabs, oysters, clams, benthic sipunculids, etc.; the growth parameters include organism size, weight gain rate, biomass, density, etc.;

[0068] Construct a bubble chart, import the growth parameters of each aquaculture organism under different mangrove planting conditions into the bubble chart for plotting and analysis, and obtain the growth bubble volumes of each aquaculture organism in the cases of no mangrove planting, single-species mangrove planting, and mixed planting of multiple mangroves;

[0069] Analyze one by one the growth bubble volumes corresponding to each aquaculture organism in the cases of no mangrove planting, single-species mangrove planting, and mixed planting of multiple mangroves, obtain multiple growth bubble volume change trends, and determine the coupling and symbiosis effect coefficients of each aquaculture organism in the cases of no mangrove planting, single-species mangrove planting, and mixed planting of multiple mangroves according to the multiple growth bubble volume change trends.

[0070] It should be noted that mangrove plants can provide nutritional support for symbiotic economic animals. Since there are many types of mangrove plants, there are differences in the coupling and symbiosis effects between different types of mangrove plants for different aquaculture organisms. Therefore, it is still necessary to conduct simulation experiments on the mangrove planting-aquaculture coupling model through this simulation platform. This method first obtains the growth parameters of different aquaculture organisms put into the simulation platform after simulated cultivation and aquaculture coupling under different mangrove planting conditions, and compares and calculates the coupling and symbiosis effect coefficients of each aquaculture organism in the cases of no mangrove planting, single-species mangrove planting, and mixed planting of multiple mangroves by constructing a bubble chart, so as to quickly and accurately determine the coupling and symbiosis effects of different mangrove planting conditions and different aquaculture animals, for the operator to extract the key parameters of the cultivation and aquaculture coupling model for the planning and formulation of the actual mangrove planting-aquaculture coupling plan, and provide a scientific basis for the selection of mangrove seedlings and aquaculture organisms in the cultivation and aquaculture coupling system, with high reliability.

[0071] Further, in a preferred embodiment of the present invention, the following steps are further included:

[0072] During the simulated aquaculture process, the water quality of aquaculture water bodies is detected and analyzed at fixed points to obtain the water quality indicators of aquaculture wastewater under different mangrove planting conditions. Among them, the water quality indicators include chemical oxygen demand, biological oxygen demand, nitrate, nitrite, phosphate, ammonia salt, heavy metals, etc.

[0073] Based on the big data network, several qualified thresholds of water quality indicators for aquaculture water bodies under various mangrove planting conditions are obtained. The Newton interpolation algorithm is introduced to interpolate and fit the several qualified thresholds of water quality indicators to construct an evaluation model for the water quality purification effect of mangroves on aquaculture water bodies.

[0074] The water quality indicators of aquaculture wastewater under different mangrove planting conditions are imported into the evaluation model for evaluation, and the water quality purification evaluation scores without mangrove planting, the water quality purification evaluation scores for single mangrove planting, and the water quality purification evaluation scores for mixed planting of multiple mangroves are generated.

[0075] According to the water quality purification evaluation scores without mangrove planting, the water quality purification evaluation scores for single mangrove planting, and the water quality purification evaluation scores for mixed planting of multiple mangroves, the water quality purification effects of aquaculture water bodies under different mangrove planting conditions are determined. According to the water quality purification effects, key parameters are provided for the mangrove planting-aquaculture coupling mode for practical application.

[0076] Comprehensively analyze the coupling symbiosis effect coefficients of each aquaculture organism under the conditions of no mangrove planting, single mangrove planting, and mixed planting of multiple mangroves, and the water quality purification effect parameters of aquaculture water bodies under different mangrove planting conditions, and plan the best mangrove planting-aquaculture coupling scheme.

[0077] It should be noted that mangrove plants have an objective purification effect on pollutants such as excessive N, P, and heavy metals in water bodies, which can reduce the incidence of diseases in aquaculture organisms. However, there are many types of mangrove plants, so there are differences in the purification effects of different types of mangrove plants. Therefore, simulation experiments can be carried out through this simulation platform to analyze the water quality indicators of aquaculture water bodies under different mangrove planting conditions, so as to evaluate and verify the purification effects of different mangrove species on aquaculture water bodies. Among them, the different mangrove planting conditions include no mangrove planting, single-species mangrove planting, and multiple-species mangrove mixed planting. Since the qualified thresholds of various water quality indicators can determine whether each water quality indicator meets the standard and can be used to objectively evaluate the purification effects of different mangrove planting conditions on the water quality of aquaculture water bodies, the qualified thresholds of several water quality indicators of aquaculture water bodies in natural tidal flat sea areas can be obtained based on the big data network, and the Newton interpolation algorithm can be introduced to construct an evaluation model for the purification effect of mangroves on the water quality of aquaculture water bodies. Then, the water quality indicators of aquaculture water bodies detected under different mangrove planting conditions are imported into the water quality purification effect evaluation model for evaluation, and the water quality purification evaluation scores under different mangrove planting conditions are obtained. According to the water quality purification evaluation scores, the purification effects of different mangrove plantings on the water quality of aquaculture water bodies can be accurately evaluated; the coupling symbiosis effect coefficients of each aquaculture organism under the conditions of no mangrove planting, single-species mangrove planting, and multiple-species mangrove mixed planting and the water quality purification effect parameters of aquaculture water bodies under different mangrove planting conditions are comprehensively analyzed to provide key parameters and scientific basis for operators to plan and formulate the best mangrove planting-aquaculture coupling scheme and to improve the sustainability of the mangrove planting-aquaculture coupling mode.

[0078] The above is inspired by the ideal embodiments of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
