TECHNICAL FIELD
[0001] The present application relates to the technical field of environmental protection, in particular to a seeding device for trans-sea seaweed introduction and an evaluation system thereof. BACKGROUND
[0002] Seagrass bed is an important near-shore ecosystem, which has key ecological functions such as maintaining biodiversity, purifying water quality, stabilizing seabed and carbon sequestration. However, affected by human activities and climate change, the global seagrass bed resources are declining rapidly. In order to restore the damaged ecosystem, trans-sea seaweed introduction has become a key technical means to restore and expand seagrass resources. This technology aims to introduce seagrass plants or seeds from healthy source habitats to target degraded areas to rebuild seagrass communities. However, trans-sea introduction faces many challenges such as unstable planting success rate in target areas, and efficient and reliable introduction technology and equipment need to be developed.
[0003] In the prior art, at present, seed-based introduction methods are favored due to their small damage to source habitats and potential for large-scale application. In the prior art, mature and healthy seagrass seeds are usually collected and screened by divers first, then the seeds are mixed with water to form a seed slurry, and a pump body system (such as SP-80 self-priming centrifugal pump) installed on a ship is used for seeding. The pump body sprays the seed slurry to the target seabed area through a pipeline, thereby achieving introduction.
[0004] However, in this seeding method, the pump blades are prone to damage the seeds when the pump discharges the seeds, which seriously reduces the survival rate of the seeds, and the seed slurry is prone to aggregation, which affects the distribution of the seeds and the repair effect of the sea area. Therefore, it is necessary to propose a seeding device for trans-sea seaweed introduction and an evaluation system thereof, which can effectively reduce the damage risk of seeds, improve the survival rate of seeds, and improve the uniformity of seeding. SUMMARY
[0005] To solve the above problems, the present application provides a seeding device for trans-sea seaweed introduction and an evaluation system thereof. Through the design of the seeding ring and the top rod, the seaweed seeds are uniformly collected into the conical hole for storage through the rotation of the seeding ring, and the seeding ring and the top rod are synchronously rotated, the top rod uniformly pushes the seeds in the seeding ring to the outside of the conical hole, thereby achieving uniform seeding and not cutting the seeds, thereby effectively reducing the damage risk of the seeds and improving the survival rate of the seeds.
[0006] In order to achieve the above object, the technical scheme of the present application is as follows: A device for introducing seeds of sea grass across a sea area, comprising a base, a seed introduction ring rotatably connected to the side wall of the base, a plurality of tapered holes for storing seeds of sea grass are formed in the seed introduction ring, the diameter of the bottom of the tapered hole is smaller than the diameter of the top, a protective frame is rotatably connected to the top of the seed introduction ring, a plurality of rotating columns are rotatably connected to the side wall of the protective frame, and a plurality of top rods for extruding the seeds of sea grass in the tapered hole are fixedly connected to the side wall of the rotating column; a driving assembly is arranged in the protective frame for driving the rotating column and the seed introduction ring to rotate, thereby uniformly dispersing and sowing the seeds of sea grass; a seed inoculation box is fixedly connected to the top of the base, and a cover plate is hingedly connected to the top of the seed inoculation box; the outer side wall of the seed inoculation box is fixedly connected to the inner side wall of the protective frame; a discharge pipe is communicated with the bottom of the seed inoculation box, and a discharge assembly for discharging a certain amount of seeds of sea grass into the protective frame is arranged in the seed inoculation box; an intercepting assembly for intercepting the seeds of sea grass and uniformly distributing them into the tapered hole is arranged at the bottom of the seed inoculation box; and a moving assembly for moving the device as a whole along the surface of the seabed is arranged at the bottom of the base.
[0007] The technical principle of the above scheme is as follows:
[0008] The diameter of the bottom of the tapered hole is slightly smaller than the diameter of the mature sea grass seed, the sea grass seeds are stored in the seed inoculation box and transported to the target sea area, the device as a whole is placed on the surface of the target seabed, the moving assembly drives the device to move uniformly along the surface of the target seabed, the discharge assembly discharges a specified weight of sea grass seeds into the protective frame, and the driving assembly drives the rotating column and the seed introduction ring to rotate synchronously, the sea grass seeds are uniformly introduced into the tapered hole under the action of the seed introduction ring, since the diameter of the mature sea grass seed is larger than the diameter of the bottom of the tapered hole, each tapered hole can only accommodate one seed, and the seed cannot pass through the bottom of the tapered hole without external force; when the rotating column and the seed introduction ring rotate synchronously, the top rod will extrude the seed in each tapered hole in turn, the seed will be elastically deformed and pass through the bottom of the tapered hole, and the device moves at the same time, the seeds are uniformly dropped onto the surface of the seabed, and the introduction work is completed.
[0009] The above scheme has the following beneficial effects:
[0010] 1. The seed introduction device in the prior art has the problems of uneven distribution of seeds during sowing, poor sea area restoration effect, insufficient resources in some areas due to excessive concentration of seeds, interspecific competition, low seed survival rate, insufficient coverage of seabed introduction due to excessive sparseness, and influence on sea area restoration effect. The present application can uniformly and independently disperse and store a large number of mature sea grass seeds through the size and structure design of the tapered hole, and can uniformly sow the mature sea grass seeds on the surface of the target seabed through the synchronous rotation design of the rotating column and the seed introduction ring and the uniform movement of the device, thereby improving the seed survival rate and the uniformity of distribution, and further improving the sea area restoration effect.
[0011] 2、The prior art seed introduction device is prone to damage (such as cutting, stirring and collision) to the seeds during discharge, and the present application can discharge the eelgrass seeds from the conical hole by slightly extruding the eelgrass seeds in the conical hole with the ejector rod, the elastic deformation of the eelgrass seeds during the process is far lower than the maximum deformation that the eelgrass seeds can withstand, and the eelgrass seeds are not damaged by cutting, stirring and collision, thereby effectively ensuring the integrity of the eelgrass seeds and further improving the seed survival rate and the effect of sea area restoration.
[0012] 3、Immature eelgrass seeds are difficult to survive after introduction, and the present application can automatically screen the eelgrass seeds through the structure and size design of the conical hole, since the diameter of the immature eelgrass seeds is smaller than the diameter of the bottom of the conical hole, the immature eelgrass seeds can directly pass through the conical hole and are not intercepted by the conical hole, thereby achieving automatic screening of eelgrass seeds of different diameters and ensuring the uniformity of sowing of mature seeds, thereby further improving the effect of sea area restoration.
[0013] Further, the driving assembly comprises a controller and a driving member embeddedly installed in the protective frame, the output shaft of the driving member is coaxially fixedly connected with the adjacent rotating column, the controller is used for controlling the driving member to run and drive the rotating column to rotate, and the rotating column is provided with a transmission assembly for driving the seed introduction ring to rotate.
[0014] Beneficial effect: the operator only needs to start the driving member through the controller, so as to quickly drive the rotating column to rotate, which is simple in operation and can effectively improve the seed introduction efficiency.
[0015] Further, the transmission assembly comprises a first gear ring fixedly connected to the rotating column, and the top of the seed introduction ring is fixedly connected with a second gear ring, and the first gear ring is engaged with the second gear ring.
[0016] Beneficial effect: the present application can effectively drive the rotating column and the seed introduction ring by using a single driving member through the design of the first gear ring and the second gear ring, thereby effectively reducing the production cost of the device.
[0017] Further, the upper part of the base is conical.
[0018] Beneficial effect: the eelgrass seeds may roll to other positions during the discharge of the seeds to the top of the seed introduction ring and the rotation of the seed introduction ring, the conical upper part of the base can limit the seeds and reduce the rolling space of the seeds, and the conical surface can also guide the seeds into the seed introduction ring, thereby improving the stability and feasibility of the seed introduction work.
[0019] Further, the intercepting assembly comprises an intercepting plate fixedly connected to the bottom of the seeding box, the side wall of the intercepting plate is fixedly connected to the upper side wall of the base, and the bottom of the intercepting plate is in sliding fit with the top of the seeding ring.
[0020] Beneficial effects: the design of the intercepting plate can prevent the seeds from rolling irregularly when the seeds are discharged to the top of the seeding ring and during the rotation of the seeding ring, thereby greatly reducing the irregular rolling behavior of the seeds. In combination with the limiting effect of the upper part of the base, the seeds can be stably concentrated on the top of the seeding ring, thereby further improving the stability and feasibility of the seeding work.
[0021] Further, the discharging assembly comprises a control valve fixedly connected to the top of the discharge pipe, and a controller for controlling the operation of the control valve; the inner side wall of the seeding box is hingedly connected with a weighing plate, the weighing plate is embeddedly installed with a pressure sensor for collecting the weight of the seaweed seeds, and the controller is used to receive the pressure signal collected by the pressure sensor; the seeding box is provided with a rotating assembly for driving the rotation of the weighing plate.
[0022] Beneficial effects: the pressure sensor can monitor the total weight of the seaweed seeds on the weighing plate. When the total weight of the seaweed seeds on the weighing plate meets the seeding demand, the operator can stop collecting. When seeding is needed, the weighing plate is driven to rotate by the rotating assembly, and then the seaweed seeds above the weighing plate are guided to be discharged to the control valve. By opening the control valve through the controller, the seeds can be transported to the top of the seeding ring.
[0023] Further, the rotating assembly comprises a telescopic piece hingedly connected to the inner bottom wall of the seeding box, the output shaft of the telescopic piece is hingedly connected to the bottom of the weighing plate, and the controller is used to control the operation of the telescopic piece and thereby control the rotation of the weighing plate.
[0024] Beneficial effects: when the output shaft of the telescopic piece is retracted, the weighing plate will rotate downward, thereby guiding the seaweed seeds to be discharged to the control valve; when the output shaft of the telescopic piece is extended, the weighing plate will rotate upward, thereby intercepting and weighing the seaweed seeds.
[0025] Further, the moving assembly comprises a plurality of track wheels installed at the bottom of the base, and the controller is used to control the operation of the track wheels and thereby drive the overall movement of the device.
[0026] Beneficial effects: the user can start the track wheels through the controller to drive the overall movement of the device at a constant speed along the surface of the seabed. The track wheels can better adapt to the uneven surface of the seabed and improve the stability of movement.
[0027] Further, the top of the seeding ring is rotationally connected with a baffle for preventing the seaweed seeds from entering between the first tooth ring and the second tooth ring, the top of the baffle is fixedly connected to the bottom of the seeding box, and a plurality of rotating holes for the rotation of the rotating column are formed in the baffle.
[0028] Beneficial effects: the baffle can prevent the sea grass seeds from entering between the first tooth ring and the second tooth ring without affecting the rotation of the rotating column, avoid the sea grass seeds from being damaged by the extrusion of the first tooth ring and the second tooth ring, and also avoid the sea grass seeds from affecting the normal operation of the first tooth ring and the second tooth ring.
[0029] Further, an introduction evaluation system for sea grass introduction across sea areas includes an environment evaluation module, a seeding efficiency evaluation module, an uniformity evaluation module, and a comprehensive evaluation module.
[0030] The environment evaluation module is used to collect the water depth, water temperature, salinity, and seabed light intensity of the seed collection environment and the seeding environment, generate seed collection environment parameters and seeding environment parameters, calculate the environment similarity, generate an environment evaluation report, and transmit it to the comprehensive evaluation module.
[0031] The calculation formula of the environment similarity is as follows:
[0032] Delta H = |H1-H2| (1);
[0033] Delta T = |T1-T2| (2);
[0034] Delta S = |S1-S2| (3);
[0035] Delta G = |G1-G2| (4);
[0036] W = 1-(Delta H + Delta T + Delta S + Delta G) / 4 (5);
[0037] Wherein, H1, T1, S1 and G1 are the water depth, water temperature, salinity and seabed light intensity of the seed collection environment, H2, T2, S2 and G2 are the water depth, water temperature, salinity and seabed light intensity of the seeding environment, Delta H, Delta T, Delta S and Delta G are the difference values of water depth, water temperature, salinity and seabed light intensity, and W is the environment similarity.
[0038] The seeding efficiency evaluation module is used to monitor the total weight change of the sea grass seeds on the top of the weighing plate and the total seeding time during the seeding process, judge the current total seeding amount based on the current total weight change, calculate the seeding efficiency based on the total seeding amount and the total seeding time, and generate a seeding efficiency evaluation report and transmit it to the comprehensive evaluation module.
[0039] The calculation formula of the seeding efficiency is as follows:
[0040] E = Delta M / T (6);
[0041] Wherein, Delta M is the total seeding amount, T is the total seeding time, and E is the seeding efficiency.
[0042] The uniformity assessment module is used to set the density threshold; it is also used to monitor the rotation speed of the rotating column and the overall moving speed of the device in real time, and calculate the sowing density based on the overall moving speed of the device and the rotation speed of the rotating column; it calculates the sowing uniformity based on the sowing density and the density threshold, generates a uniformity assessment report, and transmits it to the comprehensive assessment module.
[0043] The formula for calculating sowing uniformity is as follows:
[0044] P=K·V1 / V2 (7;
[0045] U = 1 - [|P - P0| / P0] (8);
[0046] Wherein, U is the sowing uniformity, with a minimum value of 0 and a maximum value of 1, P is the sowing density, P0 is the density threshold, K is the number of top rods, V1 is the rotational speed of the rotating column, and V2 is the overall moving speed of the device.
[0047] The comprehensive evaluation module is used to calculate the comprehensive score of the current introduction work based on the environmental assessment report, the sowing efficiency assessment report, and the uniformity assessment report, and generate a comprehensive evaluation report.
[0048] The formula for calculating the overall score is as follows:
[0049] Z = W + E + U (9);
[0050] Z represents the overall score.
[0051] Beneficial effects: This solution breaks down the previously difficult-to-quantify sowing operation into multiple measurable indicators such as environment, efficiency, and uniformity. By generating data-driven evaluation reports on environment, efficiency, and uniformity, users can accurately grasp the quality and effectiveness of each sowing operation. The environmental assessment module compares the environmental parameters (water depth, water temperature, salinity, and seabed light intensity, etc.) of the inoculation site (seed source) and the sowing site, enabling early prediction of the seagrass's adaptability potential in the new environment. Furthermore, the evaluation of sowing efficiency and uniformity provides a direct reflection of the quality of the introduction work.

[0062] The following detailed description illustrates the specific implementation method:
[0063] Example 1:
[0064] like Figure 1 andFigure 2 As shown, an introduction device for introducing seagrass seeds across sea areas includes a base 1, an introduction ring 2 rotatably fitted to the side wall of the base 1, a plurality of conical holes for storing seagrass seeds on the introduction ring 2, the bottom diameter of the conical holes being smaller than the top diameter, a protective frame 3 rotatably connected to the top of the introduction ring 2, a plurality of rotating columns 6 rotatably fitted to the side wall of the protective frame 3, and a plurality of top rods 8 welded to the side wall of each rotating column 6 for squeezing the seagrass seeds in the conical holes; a drive component is provided inside the protective frame 3 for driving the rotating columns 6 and the introduction ring 2 to rotate, thereby evenly dispersing and sowing the seagrass seeds.
[0065] The bottom diameter of the conical hole is slightly smaller than the diameter of a mature seagrass seed (approximately 90% of the diameter of a mature seagrass seed; users can design the size of the conical hole according to the actual diameter of the seagrass seeds they introduce).
[0066] like Figure 1 and Figure 2 As shown, the top of the base 1 is bolted to the inoculation box 4, and the top of the inoculation box 4 is hinged to the cover plate 15; the outer wall of the inoculation box 4 is bolted to the inner wall of the protective frame 3; the bottom of the inoculation box 4 is connected to the discharge pipe 11, and the inoculation box 4 is equipped with a discharge component for quantitatively discharging seaweed seeds into the protective frame 3; the bottom of the inoculation box 4 is equipped with an interception component for intercepting seaweed seeds so that the seaweed seeds are evenly distributed into the conical hole; the bottom of the base 1 is equipped with a moving component for moving the entire device along the seabed surface.
[0067] like Figure 2 As shown, the drive assembly includes a controller and a drive component (a waterproof motor is selected in this embodiment) embedded in the protective frame 3. The output shaft of the drive component is coaxially bolted to the adjacent rotating column 6. The controller is used to control the operation of the drive component, thereby driving the rotating column 6 to rotate. Each rotating column 6 is equipped with a transmission component for driving the seed-introducing ring 2 to rotate.
[0068] like Figure 3 and Figure 4 As shown, each transmission component includes a first toothed ring 7 bolted to the rotating column 6; a second toothed ring 9 is bolted to the top of the seed-introducing ring 2, and the first toothed ring 7 meshes with the second toothed ring 9.
[0069] like Figure 3 As shown, the upper part of the base 1 is conical; the interception assembly includes an interception plate 13 bolted to the bottom of the inoculation box 4, the side wall of the interception plate 13 is bolted to the upper side wall of the base 1, and the bottom of the interception plate 13 is slidably engaged with the top of the seed introduction ring 2.
[0070] like Figure 2As shown, the discharge assembly includes a control valve 12 fixedly bonded to the top of the discharge pipe 11, and a controller for controlling the operation of the control valve 12; a weighing plate 14 is hinged to the inner wall of the inoculation box 4, and a pressure sensor for collecting the weight of seaweed seeds is embedded in the weighing plate 14, and the controller is used to receive the pressure signal collected by the pressure sensor; a rotating assembly for driving the weighing plate 14 to rotate is provided inside the inoculation box 4. The rotating assembly includes a telescopic member 16 (an electric cylinder is used in this embodiment) hinged to the bottom wall of the inoculation box 4, the output shaft of the telescopic member 16 is hinged to the bottom of the weighing plate 14, and the controller is used to control the operation of the telescopic member 16, thereby controlling the rotation of the weighing plate 14.
[0071] like Figure 1 As shown, the moving component includes several track wheels 5 installed at the bottom of the base 1. The controller is used to control the operation of the track wheels 5, thereby driving the entire device to move.
[0072] like Figure 2 and Figure 3 As shown, the top of the seed introduction ring 2 is rotatably connected to a baffle 10 to prevent seaweed seeds from entering between the first toothed ring 7 and the second toothed ring 9. The top of the baffle 10 is welded and fixed to the bottom of the inoculation box 4. Each baffle 10 has several rotating holes for the rotating column 6 to rotate.
[0073] Specifically, such as Figure 2 As shown, in the initial state, the weighing plate 14 is horizontal, the cover plate 15 is closed, and the control valve 12 is closed.
[0074] First, the operator collects target seagrass seeds in the sampling area, then opens the cover 15 and puts the collected seagrass seeds into the inoculation box 4 for storage. The weighing plate 14 weighs the seagrass seeds in the inoculation box 4, so that the operator can determine whether the collected seagrass seeds are sufficient according to the required amount. After collection, the device and its seagrass seeds are transported to the target sea area, and then the entire device is placed on the surface of the target seabed to start the inoculation work.
[0075] In this process, such as Figure 2 As shown, the operator controls the output shaft of the telescopic component 16 to retract via the controller. At this time, the weighing plate 14 will rotate downward around its hinge point, and its left side will fit against the bottom of the inoculation box 4, thereby guiding the seaweed seeds to be discharged to the control valve 12. The operator then activates the control valve 12 via the controller, thereby discharging the seaweed seeds into the protective frame 3, and they will accumulate on the top of the seed introduction ring 2 under the limiting action of the baffle 10 and the upper part of the base 1.
[0076] Then, the operator can start the track wheel 5 through the controller, thereby driving the entire device to move at a constant speed along the seabed surface (the track wheel 5 can better adapt to the uneven surface of the seabed and improve the stability of movement). At the same time, the controller starts the drive unit, and the output shaft of the drive unit will drive one set of rotating columns 6, push rods 8 and first toothed rings 7 to rotate clockwise. Since the first toothed ring 7 meshes with the second toothed ring 9, the first gear will drive the second toothed ring 9 and the seed-introducing ring 2 to rotate clockwise. The second toothed ring 9 will also drive the other first gears, rotating columns 6 and push rods 8 to rotate. During the rotation, the seed-introducing ring 2 will drive the seeds to move towards the interceptor plate 13. Since the bottom of the interceptor plate 13 and the top of the seed-introducing ring 2 slide together, only the seeds that enter the conical hole can pass through the interceptor plate 13. Due to the relative movement between the interceptor plate 13 and the conical hole, the interceptor plate 13 will also push the seeds into the conical hole, thereby dispersing and storing the seaweed seeds in large quantities and evenly and independently into the conical hole.
[0077] Since the diameter of mature seagrass seeds is larger than the bottom of the conical hole, each conical hole can only hold one seed, and the seed cannot pass through the bottom of the conical hole without external force. When the rotating column 6 and the seed introduction ring 2 rotate synchronously, the top rod 8 will squeeze the seed in each conical hole in turn. The seed will undergo elastic deformation and pass through the bottom of the conical hole. As the device moves, the seed will fall evenly to the seabed surface, completing the seed introduction work.
[0078] In this process, since the diameter of immature seagrass seeds is smaller than the diameter of the bottom of the conical hole, the immature seagrass seeds will pass directly through the conical hole without being intercepted, thus realizing the automatic screening of seagrass seeds of different diameters. Furthermore, since immature seagrass seeds are difficult to survive after introduction, this embodiment can effectively ensure the uniformity of sowing of mature seeds, thereby improving the marine restoration effect.
[0079] During the process of seed placement on top of the introduction ring 2 and the rotation of the introduction ring 2, seagrass seeds may roll to other positions. The conical upper part of the base 1 can limit the seeds, reducing their rolling space. At the same time, the conical surface will guide the seeds back into the introduction ring 2, thereby improving the stability and feasibility of the introduction work. The interceptor plate 13 can directly and significantly reduce the irregular rolling behavior of the seeds. Combined with the limiting effect of the upper part of the base 1, the seeds will be stably concentrated on the top of the introduction ring 2, further improving the stability and feasibility of the introduction work.
[0080] The baffle 10 can prevent seaweed seeds from entering between the first toothed ring 7 and the second toothed ring 9 without affecting the rotation of the rotating column 6, thus avoiding damage to the seaweed seeds due to the squeezing of the first toothed ring 7 and the second toothed ring 9, and also preventing the seaweed seeds from affecting the normal operation of the first toothed ring 7 and the second toothed ring 9.
[0081] Existing seed introduction devices often suffer from uneven seed distribution during sowing, leading to poor marine restoration results. Overly dense seed distribution can cause resource shortages in some areas, resulting in interspecific competition and low seed survival rates. Conversely, overly sparse distribution can result in insufficient seabed coverage, further hindering restoration. This embodiment utilizes the size and structure design of a conical orifice to automate the screening and storage of seagrass seeds. Furthermore, the synchronous rotation of the rotating column 6 and the seed introduction ring 2, combined with the uniform movement of the device, ensures that mature seagrass seeds are evenly distributed onto the target seabed surface, improving seed survival rate and distribution uniformity, thereby enhancing marine restoration effectiveness.
[0082] Existing seed-introducing devices are prone to damaging the seeds during seed discharge (e.g., cutting, stirring, and collision). This embodiment, through the linkage design of the conical hole and the top rod 8, only requires slight squeezing of the seaweed seeds in the conical hole by the top rod 8, allowing the seaweed seeds to be discharged from the conical hole. During this process, the elastic deformation of the seaweed seeds is far lower than the maximum deformation they can withstand, and it does not cause hard damage such as cutting, stirring, and collision, effectively ensuring the integrity of the seaweed seeds, thereby further improving the seed survival rate and the marine restoration effect.
[0083] Example 2:
[0084] like Figure 5 As shown, unlike the above embodiments, an introduction evaluation system for cross-sea seagrass introduction includes an environmental evaluation module, a sowing efficiency evaluation module, a uniformity evaluation module, and a comprehensive evaluation module; all modules are interconnected.
[0085] The specific functions of each module are as follows:
[0086] The environmental assessment module is used to collect water depth, water temperature, salinity, and seabed light intensity of the seed collection and sowing environments, generate seed collection environment parameters and sowing environment parameters, calculate environmental similarity, generate an environmental assessment report, and transmit it to the comprehensive assessment module.
[0087] Specifically, each factor is first normalized (water depth, water temperature, salinity, and seabed light intensity), with a maximum value of 1 and a minimum value of 0. Then, the difference value of each factor is calculated, where the difference value = seed collection environment factor - sowing environment factor. Finally, the environmental similarity is calculated based on each difference value.
[0088] The formula for calculating environmental similarity is as follows:
[0089] ΔH = |H1-H2| (1);
[0090] ΔT = |T1 - T2| (2);
[0091] ΔS = |S1-S2| (3);
[0092] ΔG = |G1-G2| (4);
[0093] W=1-(ΔH+ΔT+ΔS+ΔG) / 4 (5);
[0094] Where H1, T1, S1 and G1 are the water depth, water temperature, salinity and seabed light intensity of the seed collection environment, respectively; H2, T2, S2 and G2 are the water depth, water temperature, salinity and seabed light intensity of the sowing environment, respectively; ΔH, ΔT, ΔS and ΔG are the differences in water depth, water temperature, salinity and seabed light intensity, respectively; and W is the environmental similarity.
[0095] The higher the environmental similarity, the more suitable the sowing environment is for the growth and development of the collected seagrass seeds, which in turn indicates a better seabed restoration effect. The environmental assessment module will also generate a corresponding environmental assessment report, such as:
[0096] Similarity > 80%: The environment is assessed as excellent, highly suitable for introduction work, with a high expected survival rate and excellent restoration effect.
[0097] Similarity 60%-80%: The environment is assessed as good, suitable for introduction work, with a high expected survival rate and good restoration effect. Specific difference factors need to be monitored.
[0098] Similarity 40%-60%: This environment carries certain risks, and the survival rate may be affected. It is recommended to plant with caution or choose a better region.
[0099] Similarity <40%: This environment is not suitable for the introduction of this species. It is recommended to cancel the sowing to avoid wasting resources.
[0100] The sowing efficiency assessment module is used to monitor the total weight change of the seaweed seeds on the top of the weighing plate 14 and the total sowing time in real time during the sowing process. Based on the current total weight change, it determines the current total sowing amount, calculates the sowing efficiency based on the total sowing amount and the total sowing time, and generates a sowing efficiency assessment report and transmits it to the comprehensive assessment module.
[0101] Specifically, the formula for calculating sowing efficiency is as follows:
[0102] E=ΔM / T (6;
[0103] Where ΔM is the total seeding amount, T is the total seeding time, and E is the seeding efficiency. Formula (6) directly represents the weight of seeds sown per unit time, which is the most intuitive indicator for measuring the speed of operation, and operators can quickly judge the current seeding efficiency.
[0104] The uniformity assessment module is used to set the density threshold; it is also used to monitor the rotation speed of the rotating column 6 and the overall moving speed of the device in real time, and calculate the sowing density based on the overall moving speed of the device and the rotation speed of the rotating column 6; it calculates the sowing uniformity based on the sowing density and the density threshold, generates a uniformity assessment report, and transmits it to the comprehensive assessment module.
[0105] Specifically, the formula for calculating sowing uniformity is as follows:
[0106] P=K·V1 / V2 (7;
[0107] U = 1 - [|P - P0| / P0] (8);
[0108] Wherein, U is the sowing uniformity, with a minimum value of 0 and a maximum value of 1, P is the sowing density, P0 is the density threshold, K is the number of top rods (8), V1 is the rotational speed of the rotating column (6), and V2 is the overall moving speed of the device.
[0109] The uniformity assessment module generates a uniformity assessment report, for example:
[0110] U≥90%: The height is uniform, the sowing density is consistent with the target height, and the distribution is very uniform.
[0111] 75%≤U<90%: Basically uniform, the sowing density is within an acceptable range, and the distribution is basically uniform.
[0112] U<75%: Insufficient uniformity, with a significant deviation between the sowing density and the target.
[0113] The comprehensive evaluation module is used to calculate the comprehensive score of the current introduction work based on the environmental assessment report, the sowing efficiency assessment report, and the uniformity assessment report, and generate a comprehensive evaluation report.
[0114] Specifically, the formula for calculating the overall score is as follows:
[0115] Z = W + E + U (9);
[0116] Z represents the overall score; a higher overall score indicates a better overall performance in the introduction of new species. Users can quickly assess the current status of their introduction efforts based on the comprehensive evaluation report.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
