Application of Mathematical Model Based on Fuzzy Comprehensive Evaluation
The paper introduces a fuzzy comprehensive evaluation method model, the formulation of the level pollution grade standard, and using the fuzzy mathematics were calculated by the regions for different pollution levels of membership, membership and corresponding grade product obtained the regional pollution comprehensive evaluation index, through the accurate evaluation regional pollution degree of heavy metal. This model advantage of the region's total potential ecological risk coefficient obtaining, and the model advantage of accurate evaluation of a regional heavy metal pollution degree.
