High-precision modeling method and system for attribute data of layer-control phase-control multi-constraint contaminated site

Abstract

The invention provides a high-precision modeling method and system for attribute data of a layer-control phase-control multi-constraint contaminated site, and the method comprises the steps: buildinga homogenized contaminated site geologic body three-dimensional model through employing a site geologic layered structure and a sedimentary microfacies as constraint conditions; and performing non-uniform segmentation processing on attributes in the attribute range according to the elevation of the contaminated site, and establishing attribute segmentation data; under the constraint of a geologicbody three-dimensional model, establishing a homogenized three-dimensional attribute body model for segmented data, then adooting a spatial interpolation algorithm combining a deterministic model anda non-deterministic model to carry out non-valued area control processing, and establishing a high-precision three-dimensional attribute body model; and finally, performing color separation and colormatching on the model to form a high-precision three-dimensional attribute body model under multiple constraints of layer control and phase control. Through layer control and phase control multi-constraint site pollution attribute modeling, the influence of the concentration distribution diffusivity difference of pollutants between different stratums and different phases on the three-dimensional attribute body model is eliminated, and the pollutant attribute modeling precision is improved.
