Problems solved by technology
[0005] First, it is difficult to integrate simple models into more complex integrated models because the application fields, development requirements, development environments, operating environments, and operating modes of existing simple models are generally different;
[0006] Second, in the traditional integrated modeling method, the integrated model and the actual application scenario are often tightly coupled, and the scalability of the model is poor;
[0007] Third, when the application scenario changes slightly, the integrated model needs to be rewritten or reconstructed, and the workload is relatively large;
[0008] Fourth, the integrated model is also a model, which may become part of another more complex integrated model, but the existing model integration methods lack the idea of supporting this further integration, and the existing integrated modeling environment also lacks corresponding mechanisms, making integration Models are hard to reuse

Embodiment
[0220] The invention of the present invention integrates WOFOST (crop growth model), HYDRUS-1D (unsaturated zone hydrological model) and MODFLOW (groundwater model) to simulate the action process between crop growth, unsaturated zone moisture and groundwater, thereby Study the interaction between groundwater and crops.
[0221] The growth of crops is affected by the water near the root system, and the water in the shallow layer is also affected by the vegetation and groundwater, and the water level of the groundwater interacts with the water content of the shallow surface. WOFOST is a crop growth model, which is generally used to simulate the growth process of crops such as wheat and corn; HYDRUS-1D is an unsaturated zone hydrological model, which is used to simulate shallow hydrological activities below the surface; MODFLOW is a groundwater model, which is used to simulate groundwater activities. The three models are all existing models, but they are all packaged into separat...

Description
technical field [0001] The invention relates to the technical field of computer modeling and simulation, in particular to an integrated modeling and simulation method with high scalability. Background technique [0002] Computer modeling and simulation is an important method and means to use computer-related software and hardware technology to simulate the real world, so as to explore, analyze and predict the real world. Now, computer modeling and simulation has been widely used in almost all disciplines such as industrial control, environmental monitoring, social science and natural science. [0003] With the continuous expansion of application fields, the scale of research problems is expanding, and researchers in different fields have established various simulation models. However, most of the existing simulation models are small in scale and simple in function, and are generally used to solve specific problems in the field. Therefore, it is difficult to simulate and stu...
