1. a kind of concentration distribution of pollutants map generalization method, which is characterized in that the concentration distribution of pollutants map generalization sideMethod includes:

  • Target area is divided, multiple grids are obtained;

    Each grid in the multiple grid has grid position information;

    According to the first model, the pollutant concentration data of each grid in multiple grids are determined;

    Appointing in the multiple gridOne grid is the first grid;

    First grid is divided, multiple sub-grids are obtained;

    Each sub-grid in the multiple sub-grid has sonGrid position information;

    According to cubic spline interpolation, the pollutant concentration data of first grid and the grid adjacent with first gridPollutant concentration data, determine the pollutant concentration data of each sub-grid in the multiple sub-grid;

    The pollutant concentration data of each sub-grid and preset concentration ranges are compared, determine each sub-gridColor;

    According to the color of each sub-grid and the sub-grid location information, the concentration distribution of pollutants of the first grid is determinedFigure;

    According to the concentration distribution of pollutants figure of each grid and the grid position information, the pollutant concentration of target area is determinedDistribution map.
