%X 以林芝市朗县 18 个村庄为评价对象, 采用综合污染指数法、主成分分析法两种评价法进行水质安全评价, 为避免各种评价法权重赋值对评价结果的影响, 将两种方法的评价结果运用组合的模糊 Bo rda 法进行了二次评价, 研究结果显示: 组合的模糊 Bor da 法相对综合污染指数法、主成分分析法两种方法具有较高的区分度; 经评价结果和评价排序分析可以发现综合污染指数法、主成分分析法、组合的模糊 Bor da 法 3 个排序具有相近的趋势, 较高的斯皮尔曼等级相关系数和肯达尔相关系数也证明了运用组合的模糊 Bor da 法开展农村饮用水源安全评价是可行的。林芝市朗县 18 个村庄饮用水安全评价结果表明, 帮玛村、托麦村、冲康村、堆村、卓村、来义村、列村、秀村、扎西塘村、杰村、娘村、康玛村、嘎贡村、东雄村、多龙村、热米村、拉多村、桑木村等 18 个村饮用水源安全性依次递减。  Comprehensive pollution index and principal component analysis ( PCA ) method were used to perform water safety evaluation based on drinking water sources obtained from 18 villages of Lang County in Nyingchi City. In order to avoid the influence of weight assignment on single evaluat ion method, two methods were used by combining the evaluation method based on Fuzzy Borda. The results sho wed that the combined evaluation method based on Fuzzy Borda had higher discrimination comparedto comprehensive pollution index and principal component analysis method. Results revealed that comprehensive pollution index assessment, PCA , combined evaluation method based on Fuzzy Borda had similar trend. The higherSpearman coefficient and Kendall correlation coefficient had also proven that the fuzzy Borda method was a feasible option for rural drinking water safety assessment. The results of drinking water safety evaluation assessment in 18 villages showed that the drinking source of villages such as Bangma, Tomai, Chongkang, Dui, Zhuo, Laiyi, Lie, Xiu, Zhaxitang, Jie, Niang , Kangma, Gagong, Dongxiong , Dorong, Remi, Lado and Sangmuin was turned decreasing gradually.  西藏地区自然基金( XZ 2018 ZR G220) ; 国家自然科学基金( 51868069; 51769034) ; 西藏自治区高等学校科研创新团队项目; 西藏农牧学院研究生创新计划( ST X2018204)
