Research on the Evaluation Index System of Rural Drinking Water Safety in Minhe County of Qinghai Province

研究了青海省民和县农村饮水安全评价指标体系,以《农村饮水安全评价准则》(T/CHES18-2018)中的评价指标作为一级指标,结合民和县实际情况,选取、分析了影响民和县农村饮水安全的14个二级指标。运用层次分析法和熵权法得到各评价指标权重,运用模糊综合评价得到了民和县农村饮水安全状况。研究结果表明:①对民和县农村饮水安全评价影响较大的8个指标分别为水质净化与消毒设施(备)配套率、实际供水能力、水质达标率、自来水普及率、水源保证率、取水时间/距离达标率、水质监测能力和供水保证率;②通过模糊综合评价法计算,民和县农村饮水状况得分为76.1335,表明民和县农村饮水处于安全状态。同时,还提出了需要完善配套设施、强化水源保护等民和县农村饮水安全工程建设与管理方面的几点建议。
