Problems solved by technology

[0002] For the spatial interpolation of marine pollution, the traditional spatial interpolation method uses the Euclidean distance in the weight calculation, and the reference point selection method is a fixed range or a fixed number of points. When it is used for marine pollution interpolation, it is easy to ignore two problems: (1) The ocean has " Soft "natural boundaries, the diffusion of pollutants in the ocean is affected by factors such as ocean currents, and the diffusion path is not a straight line. The diffusion path is not only affected by land barriers such as peninsulas and islands, but also largely affected by the speed and direction of ocean currents.
The traditional spatial interpolation Euclidean distance weighting method exaggerates the influence of the surrounding reference points on the interpolation points, and its fixed selection of reference points may lead to serious interpolation distortion in areas with large water quality spans, which violates the law of pollution diffusion, and the final interpolation results cannot reflect The real distribution and diffusion trend of sea area pollution

Abstract

The invention provides a sea area pollution space distribution obtaining method and device, electronic equipment and a readable storage medium. The method comprises the steps: calculating path distances between a monitoring station of a to-be-researched sea area and multiple position points of the to-be-researched sea area according to data of the to-be-researched sea area; determining an interpolation reference station meeting a set condition according to the path distance of the plurality of position points; according to the interpolation reference site and the path distance of the plurality of position points corresponding to the interpolation reference site, calculating the distance weight of a to-be-measured point of the to-be-researched sea area, wherein the to-be-measured point is a position point in the plurality of position points of the to-be-researched sea area; and according to the distance weight, obtaining sea area pollution space distribution of the to-be-researched sea area through calculation. According to the spatial interpolation method, the influence of the spatial position of the water quality monitoring point and ocean current activity on pollution diffusion is considered, and the spatial distribution and diffusion trend of pollutants under the ocean current action can be more effectively simulated.
