摘　　要：文章通过传统的内梅罗指数法、改进内梅罗指数法和单因子指数评价法对京杭大运河嘉兴段的7个水质监测断面进行评价,与传统的内梅罗指数法相比,改进的内梅罗指数法可以更好地消除污染极大值的影响,并且考虑了各评价因子的权重,可以较为全面地反映河流水质情况,使评价结果具有更好的可信度。结果表明:京杭大运河嘉兴段的7个水质监测断面水质在2019年都为Ⅲ类水质,均达到了水质类别要求。Based on 7 monitoring section samples of water quality of Jiaxing section in Beijing-Hangzhou Canal in 2019,the improved Nemerow index method was used to assess the water quality of these 7 monitoring sections of Beijing-Hangzhou Canal.Compared with single factor evaluation method and traditional Nemerow index method,the improved Nemerow index method permits more reasonable and objective assessment of water quality because it takes into account the difference and relative importance of various evaluation indexes and adopts weight factors.The results indicated that the water quality of the 7 monitoring sections in 2019 were gradeⅢ.Meanwhile,our study also showed that the improved Nemerow method may provide decision-making basis for water recourses administration.
