摘　　要：利用池州西南地区水文地质调查工作所取得的数据,采用单因子评价法和综合质量评价法进行地下水质量与污染评价。评价结果显示,潜水含水层Ⅳ类水占85%,Ⅴ类水占15%;承压含水层Ⅳ类水占26%,Ⅴ类水占74%,均无可直接饮用(Ⅰ-Ⅲ类水)的地下水。该区潜水及承压水层大部分(> 95%)受到了中度及重度污染,其中潜水层主要受到硝酸盐、亚硝酸盐和氨氮污染,而承压水层主要超标指标为铝、铁等。池州市西南地区地下水污染形势较为严峻,应尽快完成地下水污染防治规划,有效保护池州市地下水资源与环境。Based on the data obtained from the hydrogeological survey of southwestern Chizhou,the authors use both single component evaluation method and comprehensive evaluation method to evaluate the quality and pollution of the groundwater.The results show that the phreatic aquifers consist of type Ⅳgroundwater( 85%) and typeⅤgroundwater( 15%),while the pressurized aquifers consist of different percentage of type Ⅳ groundwater( 26%) and typeⅤgroundwater( 74%).Both of the two aquifers contain no groundwater water suitable for drinking directly( Ⅰ-Ⅲ level).The majority( > 95%) of the phreaticand pressurized aquifers in southwestern Chizhou were moderately and severely polluted.The phreatic aquifers were mostly polluted by nitrates,nitrites,and ammonia nitrogen,while the pressurized aquifers’ main excessive indicators are aluminum,iron,etc.The groundwater pollution situation in southwestern Chizhou is relatively serious,and the groundwater pollution prevention and control planning should be organized to effectively protect the quality of groundwater resources and environment in Chizhou City.
