| 摘 要： | 【目的】研究伊犁河河段水质特征,为其水环境污染防控提供科学依据。【方法】分别采用单因子评价法、内梅罗指数法、水质质量指数以及主成分分析法4种方法,对伊宁城市河段南北断面的水环境质量进行评价。【结果】该河流段水体综合水质状况良好,主要污染因子为总氮、总磷、化学需氧量,表现为有机污染。该河段不存在重金属污染状况。主成分分析法结果表明,A5断面水质在该河段中水质最差,整体水域表现为河段北面污染高于南面,上游断面水质好于下游断面。【结论】伊犁河伊宁河段夏季水体污染原因与生活污水、农业活动及工业污水有关。

| Abstract: | 【Objective】 In order to comprehensively understand and master the characteristics of water quality in Yili River reach, and to provide scientific basis for the prevention and control of water environment pollution. 【Method】 Four methods, single factor evaluation method, Nemerow index evaluation method, water quality index and principal component analysis were used to evaluate the quality of water environment in the north-south section of an inland urban river located in Yining.【Result】 The results of single factor evaluation method and Nemerow index evaluation method showed that the comprehensive water quality of the water body in this section was in good condition. The main pollution factors were total nitrogen, total phosphorus, and chemical oxygen demand, expressed as organic pollution. The method of water quality index showed that there was no heavy metal pollution in the river being researched. The principal component analysis showed that the water quality of A5 section was the worst in this basin. The overall water area was characterized by higher overall pollution in the north of the river section than that in the south section and the water quality of upstream section was better than that of the downstream section.【Conclusion】 The causes of summer water pollution in Yining reach of Yili River are related to domestic sewage, agricultural activities and industrial sewage. |
