摘　　要：采用模糊综合评价隶属度加权平均处理的方法,对2004～2010年大辽河营口段水质污染状况进行评价,并深入分析了水体中溶解氧含量过低的原因。结果表明,影响大辽河营口段水质的主要因素是溶解氧含量过低,2004～2010年大辽河营口段水质有逐年变好的趋势,为区域水环境综合治理提供科学依据。By using fuzzy comprehensive evaluation method of membership degree with weighted average processing,the water pollution status of Yingkou section of Daliao River during 2004-2010 were evaluated,and the reason for the low content of DO in water body was deeply analyzed.The results showed that the main factor influencing water environmental quality is the low content of DO in water body.During 2004-2010,water quality in Yingkou section,Daliao River was gradually better,which will provide scientific basis for regional water environment comprehensive control.
