摘　　要：以常州新北区为研究区域,在水文、水质及污染源调查资料的基础上,建立二维水动力水质模型,并以常州魏村水厂取水口为研究对象,建立了水源地风险等级判定模型。模型的建立主要考虑企业风险等级,以及风险发生后对水源地的影响,包括水源地水质超标倍数、水质超标持续时间以及污染团到达时间等因子,模型阈值参数根据调查及分析得到。通过模型计算得到魏村水厂取水口的风险等级,为该区域进行环境风险管理提供技术支持。Based on hydrological, water quality, and water quality model was established in the study area, pollution source data, a two-dimensional hydrodynamic and the Xinbei District in Changzhou City. A risk discrimination model was developed for the water source area at Weicun Waterworks in Changzhou City. Factors including the risk levels of the waterworks, the water quality standard exceeding rate, the duration of non-compliance, and the pollutant arriving time were incorporated into the modeling process with parameters obtained from a field survey. The risk level of Weicun Waterworks was determined using this model, which provided technical support for the management of environmental risks in this district.
