摘 要:为了研究鄱阳湖五大水系的污染现状,采用灰色关联法、单因子评价法和综合污染指数评价法,选取溶解氧、高锰酸盐指数、氨氮、总氮和总磷5个评价因子,对赣江、信江、抚河、修河和饶河水质进行了分析评价。结果表明研究水域水质总体为Ⅰ—Ⅲ类,由于农业污水排放导致五河全年总氮含量均过高,同时由于七八月份温度过高导致溶解氧含量过低。运用灰色关联法、单因子评价法和综合污染指数评价法,分析3种方法的优缺点,对比综合分析其评价结果,其中综合污染指数法和灰色关联法得出的结果较为客观,其产生的研究结果可为鄱阳湖五河水污染防治以及水质综合管理提供参考。To study the pollution status of the five water systems of Poyang Lake,this paper analyzes and evaluates the water quality of the Ganjiang River,Xinjiang River,Fuhe River,Xiuhe River,and Raohe River by adopting the gray correlation method,the single-factor evaluation method and the comprehensive pollution index evaluation method.Five evaluation factors,namely,dissolved oxygen,potassium permanganate,ammonia nitrogen,total nitrogen,and total phosphorus are selected.The results show that the overall water quality of the studied waters is between Class I and Class III,with all five rivers showing excessive total nitrogen levels throughout the year due to agricultural wastewater discharge,and low dissolved oxygen levels in July and August due to high temperatures.By using the gray correlation method,single factor evaluation method,and integrated pollution index evaluation method,the study analyzes the advantages and disadvantages of the three methods,and compares and synthesizes the evaluation results.Specifically,the integrated pollution index method and the gray correlation method provide more objective results,and the results of the study can be used as a reference for the prevention and control of water pollution in the"Five Rivers"as well as for the integrated management of water quality.
