摘要:

开展引调水工程突发水污染事件风险评价,降低突发水污染事件的危险性和危害程度,对发挥引调水工程综合效益、提高区域供水安全保障能力等具有十分重要的意义。基于驱动力-压力-状态-影响-响应(DPSIR)模型,构建能反映风险源特征和风险受体特性的引调水工程突发水污染事件风险评价指标体系,提出基于云模型的引调水工程突发水污染事件风险等级评价方法,定量评价引江济淮工程(河南段)突发水污染事件风险。结果表明,引江济淮工程(河南段)突发水污染事件风险较低,有5个评价河段的风险等级均为一般(Ⅳ级),2个评价河段的风险等级为重大(Ⅱ级),与从风险源危险性、风险受体易损性、风险控制有效性等3个方面开展的定性评价结果一致。研究结果为合理评价引调水工程突发水污染事件风险提供了新的方法,为引江济淮工程(河南段)突发水污染事件风险管理提供了依据。

Abstract:

Assessing the risks and reducing the hazard level of water pollution emergencies in water diversion projects are of prominent significance to leveraging the benefits of such projects and enhancing regional water supply safety. The Drivers-Pressures-State-Impacts-Responses (DPSIR) model was employed to establish a risk evaluation index system that reflects the characteristics of risk sources and risk receptors. A method of evaluating the risk grades of water pollution emergencies was proposed by utilizing the cloud model to quantitatively assess the risk water pollution emergency in the Henan section of the Yangtze River to Huaihe River Diversion Project. Findings revealed low risks of water pollution emergency in the studied section. Specifically, the risks of two sections were classified as significant (Level II), while five were designated as general (Level IV). These results aligned with qualitative evaluations considering risk source magnitude, risk receptor vulnerability, and risk control effectiveness. Our study offers a novel approach for assessing the risks of water pollution emergencies in water diversion projects and lays a foundation for risk management in the study area.
