Problems solved by technology
However, there are still the following problems in the existing jellyfish disaster forecasting system: there are few influencing factors considered in the forecasting, and most of them only consider the influence of wind or current, and do not consider the influence of factors such as water temperature and bait on the processes of jellyfish cleavage and growth.
The general-purpose particle tracing model is widely used, and there is a lack of targeted optimization of jellyfish life history

Embodiment Construction
[0025] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0026] Such as figure 1 , figure 2 The technical scheme of the jellyfish disaster forecast system based on the marine ecological model is shown, including the hydrological model, the low trophic level model and the jellyfish model. The hydrological model includes the water temperature, flow field and mixed layer depth of the simulated sea area; the low trophic level model includes nutrients, phytoplankton and zooplankton, and the zooplankton includes three different particles of small zooplankton, macrozooplankton and predatory zooplankton. path; the jellyfish pattern includes a transverse split module, a growth module and a mobile module. Low trophic level mode and jellyfish mode are run in online coupled mode.

The invention discloses a marine ecologic model-based jellyfish disaster forecasting method. A forecasting system comprises a hydrologic mode, a low-nutrition-level mode and a jellyfish mode; the low-nutrition-level mode provides zooplankton concentration for the jellyfish mode; and the hydrologic mode provides hydrologic, flow field and mixed layer depths for the low-nutrition-level mode and thejellyfish mode. The method comprises the steps of 1, inputting initial and forced conditions of the hydrologic mode; 2, setting parameters of the low-nutrition-level mode and the jellyfish mode; 3, inputting initial and forced conditions of the low-nutrition-level mode and the jellyfish mode; 4, running a model to obtain a calculation result; 5, performing comparison and judgment on the calculation result and observation; and 6, according to jellyfish distribution in the next year, forecasting a result. The method has the beneficial effects that the influence of factors such as a temperature,a flow field, a bait field and the like on a jellyfish disaster and life history characteristics of jellyfishes are fully considered; the model is optimized; the method has the advantages of comprehensive simulation factors and strong pertinence; and the shortcomings of single simulation factor and life history simulation deficiency are overcome.
Description
technical field [0001] The invention relates to the technical field of marine ecological numerical simulation, in particular to a jellyfish disaster forecasting system and forecasting method based on a marine ecological model. Background technique [0002] Since the 1990s, disasters caused by jellyfish outbreaks worldwide have increased day by day. Jellyfish disaster is an ecological disaster caused by the mass reproduction of jellyfish. It will not only affect the health of the ecosystem, but also block the water inlets of coastal factories and nuclear power plants, threatening production safety; block fishing nets and interfere with fishery production; sting tourists and affect coastal areas. tourism. The forecast of the quantity and distribution of jellyfish can provide reference for the production activities of fishery and coastal industry, and it is also an important basis for coastal tourism to issue early warning and forecast. However, there are still the following ...
