[0047] The present application embodiment first provides a method for simulating the marine ecological environment. Please refer to Figure 1 , Figure 1 A flow chart of a method for simulating the marine ecological environment provided in an embodiment of the present application.

[0048] like Figure 1 As shown, the simulation method of the marine ecological environment includes the following S101 to S103:

[0049] S101, running a calculation thermodynamic process based on a mass conservation ocean circulation numerical model to determine a first parameter required for simulating the ocean hydrodynamic environment of a preset ocean space.

[0050] The Mass Conservation Ocean Model (MaCOM) is a computer model used to simulate global or local ocean circulation, ocean dynamics and the interaction between the ocean and the atmosphere. The model is based on the basic physical principles of conservation of mass and momentum. It discretizes and numerically solves a set of partial differential equations describing the movement of ocean water (including the mass conservation equation, momentum conservation equation, thermodynamic equation and salinity equation, etc.) to predict and analyze the changes in ocean state parameters such as ocean temperature, salinity, flow velocity and sea level.

[0051] In the embodiment of the present application, the simulation of the marine ecological environment specifically refers to determining the distribution and concentration of marine ecological environment variables in a preset marine space. The marine ecological environment variables include at least: small phytoplankton and diatoms, two sizes of zooplankton, microzooplankton and medium zooplankton, nitrogen element variables such as nitrate, ammonium salt and particulate nitrogen, silicon element variables such as silicate and particulate silicon, phosphorus element variables such as phosphate, dissolved oxygen, dissolved inorganic carbon and total alkalinity of seawater.

[0052] In an embodiment of the present application, the purpose of the simulation method of the marine ecological environment is to couple the simulation of the marine ecological environment with the simulation of the marine hydrodynamic environment by the mass conservation ocean circulation numerical model, so that the mass conservation ocean circulation numerical model can simultaneously simulate the marine hydrodynamic environment and marine ecological environment of a preset ocean space.

[0053] The mass conservation ocean circulation numerical model includes a dynamic process and a thermodynamic process, wherein the dynamic process is used to calculate the flow rate and flow velocity of the ocean, and the thermodynamic process is used to calculate the temperature and salinity of the ocean.

[0054] The temperature and salinity in the ocean are important factors affecting the changes in the marine ecological environment. Therefore, in order to enable the mass conservation ocean circulation numerical model to simulate the ocean hydrodynamic environment and marine ecological environment of the preset ocean space at the same time, before simulating the marine ecological environment, the mass conservation ocean circulation numerical model needs to run the calculation thermodynamic process to obtain the temperature and salinity of the preset ocean space, and further realize the simulation of the marine ecological environment based on the temperature and salinity.

[0055] In an embodiment of the present application, the purpose of the above S101 is to obtain the temperature and salinity of a preset ocean space obtained by thermodynamic process calculation, and to simulate the ocean hydrodynamic environment by combining the mass conservation ocean circulation numerical model to obtain other first parameters related to the simulation of the marine ecological environment.

[0056] Wherein, the first parameter at least includes:

[0057] The upper surface forced long and short wave radiation of the preset ocean space in the ocean hydrodynamic environment, the time step integral required to simulate the ocean hydrodynamic environment, the water depth information of the preset ocean space and the pressure information corresponding to different water depths.

[0058] Furthermore, considering that when constructing the necessary data required to simulate the marine ecological environment, there may be a problem that the constructed data does not match the computer model used to simulate the marine ecological environment. In order to avoid this problem, the preset initial field data of the marine ecological environment variables, open boundary data and related parameters required for the marine ecological environment simulation operation can be matched with the computer model.

[0059] For example, the initial field data and open boundary data of preset marine ecological environment variables such as nitrate, phosphate, silicate, dissolved oxygen, and total inorganic carbon are standardized through the corresponding model codes, so that these data can be converted into the data format required for computer model data processing through the input program.

[0060] For example, through the corresponding input program, a series of data required for simulating the marine ecological environment, such as data reading and writing frequency, file storage times, whether it is an average field, maximum growth rate of phytoplankton, growth limiting factor, half-saturation constant, reference concentration, etc., are input into the computer model, and these data are converted into the data format required for computer model data processing through the input program.

[0061] S102, connecting the first parameter to the marine ecological environment of the preset ocean space to obtain a second parameter required for simulating the marine ecological environment.

[0062] The purpose of the above S102 is to convert the first parameter related to the simulation of the marine ecological environment into the second parameter required for simulating the marine ecological environment.

[0063] In the embodiment of the present application, S102 includes:

[0064] Determining illumination information of the preset ocean space in the marine ecological environment according to the upper surface forced long-wave and short-wave radiation;

[0065] Determining the daily cycle integral required for simulating the marine ecological environment according to the time step integral;

[0066] According to the water depth information and the pressure information corresponding to different water depths, the true light layer information of the preset ocean space in the marine ecological environment is determined.

[0067] That is, the upper surface long-wave and short-wave radiation of the preset ocean space in the ocean hydrodynamic environment is corresponded to the illumination information in the marine ecological environment; the time step integral used in calculating the simulated ocean hydrodynamic environment is corresponded to the daily cycle integral required for simulating the marine ecological environment; and, the water depth information of the preset ocean space in the hydrodynamic environment and the pressure information at different water depths are combined to determine the true light layer depth of the preset ocean space.

[0068] In the process of practical application, in order to better simulate the ocean hydrodynamic environment and marine ecological environment of the preset ocean space, it is necessary to grid the preset ocean space to divide the three-dimensional ocean space into a series of small, interconnected grid units, where each grid unit represents a basic computing unit.

[0069] Therefore, in order to further improve the coupling between the simulation of the marine ecological environment of the preset ocean space and the mass conservation ocean circulation numerical model, it is also necessary to unify the grid used to simulate the ocean hydrodynamic environment of the preset ocean space and the grid used to simulate the marine ecological environment.

[0070] Specifically, the process of unifying the grid used to simulate the ocean hydrodynamic environment of the preset ocean space and the grid used to simulate the ocean ecological environment includes:

[0071] Obtaining a first grid required for calculating marine ecological variables at different times when simulating the marine ecological environment of a preset marine space, and obtaining a second grid required for the mass conservation ocean circulation model to simulate the marine hydrodynamic environment of the preset marine space;

[0072] Using the first grid as a standard, aligning the second grid; or using the second grid as a standard, aligning the first grid;

[0073] The first grid and the second grid are used to divide the preset ocean space into grid units respectively.

[0074] The alignment process refers to aligning or re-dividing another grid based on the size of grid cells of one of the first grid and the second grid and the position of each grid cell.

[0075] It should be noted that the purpose of the above alignment processing of the first grid and the second grid is to make the positions and sizes of different grid units in the first grid and the second grid consistent. Therefore, in the actual application process, before simulating the marine ecological environment and marine hydrodynamic environment of the preset marine space, the preset marine space can be gridded with the same parameters to make the sizes and positions of the grid units in different environments the same.

[0076] S103, based on the initial data of the marine ecological environment variables, the temperature and salinity of the preset ocean space obtained by running the mass conservation ocean circulation numerical model to calculate the thermodynamic process, and the second parameter, to obtain the simulation result of the marine ecological environment.

[0077] The initial data are the initial field data of preset marine ecological environment variables or the marine ecological environment variables in the marine ecological environment corresponding to a specific moment.

[0078] Specifically, when the mass conservation ocean circulation numerical model is started in an initial field mode, the initial data of the marine ecological environment variables include preset initial field data of the marine ecological environment variables;

[0079] When the mass conservation ocean circulation numerical model is started by hot start at a specific moment, the initial data of the marine ecological environment variables include the marine ecological environment variables of the preset ocean space corresponding to the specific moment.

[0080] Among them, the initial field data refers to the initial data of marine ecological environment variables when the marine ecological environment simulation starts; the marine ecological environment variables of the preset marine space corresponding to a specific time refer to the marine ecological environment variables in the marine ecological environment at the specific time used when the simulation of the marine ecological environment of the preset marine space is terminated at a specific time and the simulation of the marine ecological environment is started again.

[0081] Furthermore, the above S103 includes:

[0082] Based on the initial data of the marine ecological environment variables, the temperature and salinity of the preset ocean space obtained by running the mass conservation ocean circulation numerical model to calculate the thermodynamic process, and the second parameter, determine the marine ecological environment variables in each grid cell of the preset ocean space corresponding to the target time step;

[0083] Based on the position of each grid unit in the preset ocean space and the ocean ecological environment variables in each grid unit, the simulation result of the ocean ecological environment is obtained.

[0084] That is, after determining the initial data of the marine ecological environment variables, on the basis of the initial data, combined with the illumination, daily cycle integral, true light layer depth information of the marine ecological environment and the temperature and salinity of the preset ocean space, the changes in the marine ecological environment variables in the preset ocean space are calculated to realize the simulation of the marine ecological environment for the preset ocean space.

[0085] The grid unit is an independent calculation unit, and the simulation result for the marine ecological environment is the marine ecological environment variable information in each grid unit. In order to intuitively determine the simulation result of the marine ecological environment of the preset marine area as a whole, it is also necessary to combine the positions of each grid unit in the preset marine area, splice each grid unit, and combine the concentrations of each marine ecological environment variable at different locations to derive the corresponding marine ecological environment map.

[0086] Further, in order to facilitate understanding of the simulation method of the marine ecological environment provided in the embodiment of the present application, the following is combined with Figure 2 Further explanation of the simulation process of the marine ecological environment

[0087] Please refer to Figure 2 , Figure 2 A schematic diagram of a marine ecological environment simulation provided in an embodiment of the present application.

[0088] Input module 201, calculation module 202, output processing module 203;

[0089] The input module 201 is used to receive the initial field data of the marine ecological environment variables, the relevant parameters required for the marine ecological environment simulation operation, and the open boundary data of the marine ecological environment variables.

[0090] The calculation module 202 is used to determine whether the start-up mode of the mass conservation ocean circulation numerical model capable of simulating the marine ecological environment is hot start or initial field start;

[0091] When the startup mode is the initial field startup, the calculation module 202 obtains the initial field data of the marine ecological environment variables sent by the input module 201, and inputs the initial field data of the marine ecological environment to the marine ecological environment simulation calculation unit 2021 of the calculation module;

[0092] In one case, appropriate adjustments to the data parameters may occur, resulting in the interruption of the simulation of the marine ecological environment at a specific time. At this time, the calculation module 202 will save the marine ecological environment variables corresponding to the specific time.

[0093] When the startup mode is hot start, the calculation module 202 calls the marine ecological environment variables corresponding to the specific moment and sends them to the marine ecological environment simulation calculation unit 2021.

[0094] The calculation module 202 also includes: a data docking unit 2022 .

[0095] The data docking unit 2022 is used to obtain the upper surface forced long and short wave radiation of the preset ocean space required for simulating the ocean hydrodynamic environment by the mass conservation ocean circulation numerical model, the time step integral required to simulate the ocean hydrodynamic environment, and the water depth information of the preset ocean space, and convert this information into parameters required to simulate the marine ecological environment.

[0096] Specifically, information conversion includes:

[0097] Converting the forced long-wave and short-wave radiation of the upper surface into illumination information of a preset ocean space;

[0098] Converting the time step integral into a daily cycle integral;

[0099] The water depth information and pressure information corresponding to different water depths are converted into true light layer information of a preset ocean space.

[0100] The data docking module 222 is also used to unify the grid and vertical stratification information of the preset ocean area used to simulate the ocean hydrodynamic environment and the grid and vertical stratification information of the preset ocean area used to simulate the ocean ecological environment, so that after the above-mentioned upper surface forced long and short wave radiation, the time step integral for simulating the ocean hydrodynamic environment, the water depth information of the preset ocean space and the pressure information corresponding to different water depths are converted, the grid distribution of the preset ocean area and the data corresponding to the grid can correspond to the marine ecological environment.

[0101] The data docking unit 2022 is also used to send the converted illumination information, daily cycle integral and true light layer information to the marine ecological environment simulation calculation unit 2021.

[0102] The calculation module 202 is also used to determine whether the mass conservation ocean circulation numerical model has an open boundary. If it has an open boundary, it receives the open boundary data of the marine ecological environment variables in the input module 201 and inputs it into the marine ecological environment simulation calculation unit 2021.

[0103] In the case of no open boundary, the open boundary data of the marine ecological environment variables in the input module 201 are no longer received, so that the marine ecological environment simulation calculation unit 2021 adopts the default value of the open boundary data to calculate the marine ecological environment variables.

[0104] After the marine ecological environment simulation calculation unit 2021 obtains the data input by the above modules and units, it can further calculate the cyclic increments of the marine ecological environment variables in each time step and each unit grid, and determine the marine ecological environment variables in each unit grid at each time step of the preset ocean area based on the initial field data of each unit grid or the marine ecological environment variables corresponding to a specific time combined with the cyclic increments.

[0105] The output processing module 203 receives the marine ecological environment variables in each unit grid at each time step of the preset ocean area output by the calculation module 202.

[0106] The coordinates of the positions of the various unit grids are transformed to draw a corresponding marine ecological environment simulation map in combination with the marine ecological environment variables in each unit grid at each time step in the preset marine area.

[0107] To summarize, the method for simulating the marine ecological environment provided in the present application, in the process of simulating the marine ecological environment, connects the first parameter required for simulating the marine hydrodynamic environment of a preset marine space to the marine ecological environment, and obtains the second parameter required for simulating the marine ecological environment, thereby realizing the parameter coupling of the mass conservation ocean circulation numerical model and the marine ecological environment simulation; at the same time, in the process of running the calculated thermodynamic process based on the mass conservation ocean circulation numerical model to obtain the simulated marine hydrodynamic environment, the temperature and salinity that affect the marine ecology are realized, thereby realizing the environmental coupling of the mass conservation ocean circulation numerical model and the marine ecological environment simulation, so that the mass conservation circulation numerical model can simulate the marine ecological environment while simulating the marine hydrodynamic environment.
