摘要：Heavy metal pollution is an important factor to destroy the food cultivation soil environment and directly or indirectly endanger people's food safety and healthy diet. In this study, two methods are used to evaluate soil heavy metal pollution: The first method is to establish the Nemerow index model, the degree of heavy metal pollution in urban soil is analyzed and evaluated, the Nemerow comprehensive pollution index shows the pollution level; the second method uses FIS and correlation function of MATLAB software, combined with fuzzy comprehensive evaluation method to establish the membership function of Hg and other 6 kinds of soil heavy metal pollution factors. Through the normalization of Matlab-FIS-sugeno model weights, make the membership function adapt fuzzy comprehensive evaluation of weighted fuzzy operator. Thus, we establish the fuzzy comprehensive evaluation model of heavy metal pollution in soil based on Matlab-FIS-sugeno. Respectively, using these two models to evaluate the heavy metal pollution in agricultural soils of Tongling area, the results were consistent with the actual situation.
