摘  要：
[目的]对辽河干流的水环境质量进行综合评价。[方法]利用模糊综合评价和隶属度加权平均处理方法,对2004～2010年辽河干流2个监测断面的水质污染状况进行评价,并提出辽河干流水污染治理的建议。[结果]2004～2010年,辽河干流朱尔山断面的水质为国家Ⅱ～Ⅲ类,兴安断面的水质为国家Ⅱ～Ⅳ类,总体水质明显好转。影响辽河水质的主要因素是溶解氧含量过低。同时,耗氧有机污染物的排放是造成辽河流域水质污染的主要原因,另一个不可忽视的因素是氨氮的排放。[结论]该研究为辽河干流水环境的保护和污染治理提供了科学参考。

摘  要：
[Objective] The study aims at evaluating the water environmental quality of the Liaohe River mainstream.[Method] Water quality of two monitored sections in the mainstream of the Liaohe River from 2004 to 2010 was assessed by the fuzzy comprehensive appraisal combined with weighted average,and some practicable measures were put forward according to the assessment results.[Result] From 2004 to 2010,the water quality of the Liaohe River mainstream varied from Grade Ⅱ to Ⅲ at Zhuershan section,and changed from Grade Ⅱ to Ⅳ at Xing'an section,becoming better on the whole.In addition,the major factor influencing the water quality is the small content of dissolved oxygen(DO) in the water body.Meanwhile,the pollution of the water body mainly results from the discharge of organic matter consuming oxygen largely,and ammonia nitrogen should be paid more attention to.[Conclusion] The research could provide scientific references for the protection pollution control and water environment in the mainstream of the Liaohe River.
