Fuzzy Mathematics Based Comprehensive Evaluation of Atmospheric Environmental Quality in Huaian

Consulting the standards of atmospheric environment, the atmospheric environment quality of Huaian was evaluated by using the method of fuzzy mathematics, selecting SO2 , NO2 , PM10 as evaluation factors to caculate the weight of distribution coefficients and grade attachment of atmospheric pollution factors. The results of comprehensive evaluation indicated that the atmospheric environment of Huaian was moderately polluted, and it was deteriorated year after year. The results of comprehensive evaluation using the method of fuzzy mathematics were more objective than any other normal evaluation methods.
