Abstract:A new environmental risk evaluation index system made up of 3 first-grade indicators including source indicator, process indicator and receiving indicator, and 14 second-grade indicators was established to overcome the limitation of indicators selecting and uncertainty processing in traditional evaluation methods for chemical enterprises. The evaluation system was further quantified by employing fuzzy-analytic hierarchy process programming to reduce the uncertainty of indicator’s weighted value and fuzzy membership degree to ascertain the indicator’s risk level. The newly developed method was applied to environmental risk evaluation of a given chemical enterprise in Shanghai to prove its availability. It was found that the composite environmental risk value of this enterprise could be reduced from 0.75 (risk rank Ⅳ) to 0.59 (risk rank Ⅲ) by moving it to an industrial area with population density less than 2000 person/km2 and keeping chemicals in equipment with filling ratio lower than 80%.
