摘　　要：[目的]对南充市农村生活饮用水进行水质评价,为该地生活饮用水基础设施建设提供科学依据。[方法]2009年3月对南充市41个集中式饮水工程的管网水进行9项指标的检测,计算信息熵确定各检测指标权重,采用改进的尼梅罗指数评价法对水质进行综合评价。[结果]有37份水样满足二级水质要求,合格率为90.25%,有3份水样属于放宽限制的三级水质范围,仍有1份水样完全不满足农村生活饮用水的限制要求。[结论]与传统尼梅罗指数评价法、单因子指标评价法比较,熵权尼梅罗指数法更为客观、全面,评价结果更有实际意义。[Objective] To evaluate the rural drinking water quality in Nanchong in order to provide scientific basis for infrastructure construction of drinking water.[Methods] According to the monitoring of 9 index at 41 pipe network water in Nanchong,water quality was evaluated by using Nemerow index method based on entropy weight in March 2009.[Results] The water quality category of the 37 pipe network water was below the level II with the qualified rate of 90.25%.Three water samples were the level III of liberalization of restriction.Only one water sample was above level III,and it could not satisfy the quality of rural drinking water.[Conclusion] The Nemerow index method based on entropy weight was more objective and comprehensive,and its result was more practical and applicable than single factor index method and traditional Nemerow index method.
