基于层次分析法评估长江上游宜宾段工业园区环境风险

长江宜宾段工业园区中分布着众多化工企业，对周边流域生态环境具有潜在风险。选择环境风险源、管控机制、风险受体3个准则层，包括行业类型、园区企业生产工艺、环境管理体系、环境风险管理体系、受纳水体环境等13个指标层建立评估模型体系；采用层次分析法(AHP)评估了宜宾市6家工业园区(A~F)的环境风险评。结果表明，6家工业园区准则层权重总占比表现为环境风险源(69.939)>环境风险受体(38.076)>风险管控机制(33.420)，各园区环境风险综合值表现为B园区(19.147)

Assessment of the environmental risk of the industrial parks of Yibin section of the upper reaches of the Yangtze River based on analytic hierarchy process

Many chemical enterprises are distributed in the industrial parks of Yibin section of the Yangtze River, which have potential risks to the ecological environment of the surrounding basin. There is still a lack of corresponding technical guidelines and normative references for regional environmental risk assessment such as industrial parks. Using analytic hierarchy process (AHP), the environmental risk assessment of six industrial parks (A-F) in Yibin was carried out. Three criteria layers, namely, environmental risk sources, control measures and risk receptors, and 13 index layers were selected to establish the evaluation model. The 13 index layers included industry type, production process of enterprises in the park, environmental management system, environmental risk management system and receiving water environment, etc. The results showed that the total weight proportion of the criterion layer of the six industrial parks was environmental risk source (69.939) > environmental risk receptor (38.076) > risk control mechanism (33.420). The total environmental risk values of the parks were in the order of Park B (19.147) < Park D (19.265) < Park A (22.237) < Park C (23.646) < Park F (25.838) < Park E (30.321), all belonging to medium environmental risk.
