| 摘 要： | 利用1987～2009年辽河干流8个常规监测断面的历年监测数据,通过统计分析确定辽河水质的主要污染指标为化学需氧量(COD)和氨氮,2007年前辽河水质首要污染指标是COD,2008年和2009年氨氮超过COD成为辽河水质污染首要污染指标；分析干流两项指标的时间、水期、空间分布规律,明确给出水质污染重点治理时段和河段.

| Abstract: | This paper determines the contamination indexes of Liaohe River are COD and NH3-N using 8 Liaohe River main stream sections monitoring data between 1987 and 2009. In 2008 and 2009, NH3-N has been the primary pollution index other than COD, the paper analysis this two indexes features between different spatial-temporal and water periods, and gives out the suggestions when and where is the key to make Liaohe River pollution abatement. |
