摘要
本文采用层次分析法对内江市中小型河流和水库水质安全进行了评价。结果表明,内江市水质安全总体状况在中等级别,水质安全存在一定风险。处于水质安全级别Ⅱ级以下的河流主要来自威远县和隆昌县的次级河流。采用包括水质评价、营养状态评价、健康风险评价、水质污染风险评价在内的水质安全综合评价,具有直观和定量定性的特点,能够判断水质安全度。
The water quality safety of small and medium-sized rivers and reservoirs in Neijiang was evaluation by analytic hierarchy process. The results showed that the water quality safety in Neijiang was at middle level with certain safety risk. The rivers with water quality safety level worse than grade 1I were mainly secondary revers in Weiyuan County and Longchang County. The comprehensive evaluation of water quality safety including water quality, eutrophication, health risk and water pollution risk is characterized as being intuitive, quantitative and qualitative, which can judge the level of water quality safety.
