| 中文摘要 |
| 采用模糊综合评价模型对大伙房库区下游浑河抚顺段在1996～2004年间水质状况进行评价.结果表明，在1996～2004年间该河段水质呈波动性变化；除1997、2001、2003年外，该河段的3个监测断面的年综合评价值属Ⅱ类和劣Ⅲ类水质，其主要污染物是有机污染物、油类和氨氮；但污染物变化规律各不相同，油类和氨氮呈逐年增加趋势，COD呈波动性变化，BOD5呈现逐年递减趋势. |

| Fuzzy comprehensive model was used to assess water quality state in Hunhe river of Dahuofang reservoir from 1996 to 2004. It was found that the water quality of Hunhe river changed fluctuantly and belonged to Ⅱ and serious Ⅲ state besides in 1997, 2001, and 2003.
