| 摘要: |
| 【目的】开展洛阳市伊洛河流域固定源突发性水环境风险评估。【方法】基于层次分析法，从环境风险源强度分析、环境受体脆弱性分析和环境风险防控及应急能力分析3个方面构建水环境风险评估体系，对洛阳市伊洛河流域进行固定源突发水环境风险评估。【结果】洛阳市伊洛河流域风险企业整体逼近河流，除东部的部分县区外，县区风险企业均以化工、石油、采选危害性较高的行业为主，流域整体为中高水环境风险水平，除西部洛宁和北部新安、孟津及瀍河回族区外，其余县区均为高风险地区。【结论】主导环境风险因子为环境应急指挥机制、应急设施与物资准备和最近河流距离。本研究可为伊洛河流域突发污染事件的应急响应和风险防范提供依据。 |

| Abstract: |
| 【Objective】Water pollution incidents pose a serious threat to public drinking water. Assessing watershed water environment risk is necessary to prevent and reduce impact of such incidents. Taking Yiluo River Basin in Luoyang City of Henan Province as an example, this paper proposes a method to assess its environmental risks.【Method】The analysis was based on analytic hierarchy process (AHP). We constructed an environmental risk assessment framework that encompasses three key factors: ① intensity of environmental risk sources, ② vulnerability of environmental receptors, and ③ capacity for environmental risk prevention, control, and emergency response. From this framework, a water environmental risk assessment was conducted for fixed-source pollution emergencies in the study region.【Result】The highest-risk areas in the basin are in proximity to the river. With the exception of certain counties in the eastern part of the basin, high-risk sectors are chemicals, petroleum, and hazardous material industries. Overall, the basin is in a medium-to-high environmental risk level. Specifically, most counties and districts in the basin are at high risk, except for parts of Luoning County in the west and Xin’an, Mengjin, and Chanhe Huiyuan District in the north, which show comparatively low risk levels.【Conclusion】The dominant environmental risk factors in the basin include the efficiency of emergency command mechanisms, availability of emergency facilities and materials, and proximity to the nearest river. Our findings provide a scientific basis for emergency preparedness and risk management of pollution incidents in the Yiluo River Basin. |
