摘　　要：水利水电工程的建设和施工过程中,会对周围的地下水环境产生潜在的影响。为及早发现并解决污染问题,减少对地下水资源的损害,提出了水利水电工程施工期地下水污染溯源辨识方法。通过地下水监测井采集样本,分析污染物可能产生的来源,利用梅罗综合指数方法建立地下水污染指标与等级相关模型,归一化全部因子,计算变量的方差贡献率,获得各污染指标的权重,实现污染溯源辨识。实验结果表明,所提方法能够准确追溯水利水电工程施工期地下水污染源头,便于及时作出治理措施,降低污染物浓度,改善地下水环境。The construction and construction process of water conservancy and hydropower projects may have potential impacts on the surrounding groundwater environment.In order to detect and solve pollution problems early and reduce damage to groundwater resources,a method for identifying the source of groundwater pollution during the construction period of water conservancy and hydropower projects is proposed.The study collects samples through groundwater monitoring wells to analyze the possible sources of pollutants.By establish a groundwater pollution index and level correlation model using the Merow comprehensive index method,it normalizes all factors,calculates the variance contribution rate of variables,obtains the weights of each pollution index,and achieves pollution traceability identification.The experimental results show that the proposed method can accurately trace the source of groundwater pollution during the construction period of water conservancy and hydropower projects,facilitate timely implementation of control measures,reduce pollutant concentration,and improve groundwater environment.
