China Environmental Science, 2010,30(1)：133~138 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 fu
