摘　　要：饮用水安全关系着当地居民的身体健康和生命安全.为了全面了解川西高原集中式饮用水源地水质现状和安全情况,选择了代表性地区作为研究对象,基于2014—2015年的水质数据,通过单因子进行水质现状分析.结果表明,100个地表水源地中48%水源地水质达Ⅱ类标准,93%水源地水质达Ⅲ类标准,超标的基本项目主要是总氮、溶解氧、总磷,其次是锰、铁;地下水型集中式饮用水水源地中100%水源地水质达Ⅲ类标准.通过水源地安全状况评价技术进行水质安全评价,地表水质安全指数为3级或好于3级的水源地(即合格水源地)占评价水源地总数的99%,不合格水源地1个,主要表现在铅元素超标.地下水水源地全部合格.Drinking water safety concerns the health and life safety of local residents.In order to have a comprehensive understanding of the water quality and safety situation of the centralized source of drinking water in the Western Sichuan Plateau, a representative region was selected as the research object.Based on the data of water quality in 2014-2015, through the single factor water quality situation analysis, from 100 surface water sources, water quality reaches up to 48%Ⅱ class standard, 93% water quality of Ⅲ class standard.The basic item that exceeds bid basically is total nitrogen, dissolved oxygen, total phosphorus, and other basically is manganese, iron.For groundwater type of centralized drinking water source, water quality reaches 100%Ⅲ class standard.According to the water quality safety assessment technology of water sources, the surface water quality safety index is grade 3 or better than grade 3 (i.e., qualified water sources), which accounting for 99% of the total number of water sources, and the unqualified water sources account for one, which is mainly reflected in the excessive lead.All groundwater sources are qualified.
