| 摘 要： | 以多年水质监测数据和水文资料为基础,分析COD和流量、悬浮物之间相关性,阐明悬浮物对辽河COD贡献的变化。辽河自2000年开始,流量显著下降,西辽河输沙量的减少,悬浮物对辽河COD的贡献下降;通过对比辽河和典型受到生活污水和工业废水污染的浑河COD、DO和BOD/COD比值,分析主要支流COD变化,辽河近年污染特征发生了显著变化。

| Abstract: | This paper gives the conclusion that Liao River SS in contributions to COD had been declined since 2000 based on long years quality monitoring data and hydrologic information between COD, flow and SS. By contract Liao River and Hun River＇s COD, DO and BOD COD ratio and main tributaries cod changings, we found that Liao River pollution characteristics had been significant changed in recent years. |
