摘　　要：以南流江流域玉林段为研究对象,采用单因子指数评价法、综合污染指数评价法、有机污染指数评价法三种水质评价方法对其水质污染指数进行计算,确定水质等级,并通过污染分担率计算出主要污染指标。结果表明,通过单因子指数评价法评价时,水质相对较差;通过有机污染指数评价法评价时,水质相对较好,通过综合污染指数评价法则更能客观评价南流江流域玉林段的水质。评价结果显示,南流江流域玉林段2个断面水质能够达到Ⅲ类标准,其余7个断面的水质均不能达标,主要污染指标为总磷和氨氮。评价结果对南流江流域玉林段的水质治理工作具有一定的参考作用。This paper takes Yulin section of Nanliujiang River Basin as the research object, calculates its water quality pollution index by three water quality evaluation methods: single factor index evaluation method, comprehensive pollution index evaluation method and organic pollution index evaluation method, determines the water quality grade, and calculates the main pollution index by pollution sharing rate. The results show that the water quality of Yulin section of Nanliujiang River basin is relatively poor when evaluated by single factor index method, relatively good when evaluated by organic pollution index method, and more objective by comprehensive pollution index evaluation rule. The evaluation results show that the water quality of two sections in Yulin section of Nanliujiang river basin can meet the third class standard, while the water quality of the other seven sections can not meet the standard. The main pollution indicators are total phosphorus and ammonia nitrogen. The evaluation results can be used as a reference for water quality control in Yulin section of Nanliujiang River Basin.
