The Application of Gift Value Algorithm and Stable Source Diffusion Fitting Algorithm in the Soil Pollution
this article gives weight to the study of the environmental pollution degree caused by heavy metal and the finding of the pollution source position. First of all,we rank the pollution degree by the geoaccumulation index,regard it as the assessment set,establish fuzzy relation matrix,and get the comprehensive evaluation results in order to get the pollution degree in different functional areas of a city. Secondly,on the fundation of the study on pollution source,we apply Kriging interpolation to interpolate the space,get the concerntrations in various heavy metal via the simulation which uses the stable source diffusion equation . Then,we fit the pollution degree that is caused by the assumption pollution source and the actual pollution source,and compare the fitting result to find the coordinate point that is most close to the practical pollution source. In the practical experiment,we adopt the heavy metal sample datas of one city to do the calculation. The outcome can properly reflect the contamination of the city and show the pollution source location.
