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
