摘 要:为评估伊通河长春城区段底泥的污染特征,在目标河段进行底泥样品采集,对其水理性质、总有机碳、有机质、总氮、总磷等指标进行测试分析,运用模糊综合评价法对目标河段底泥营养物质污染进行评价。结果表明:目标河段底泥pH平均值为7.22,基本呈中性。总氮、总磷平均值分别为622,639 mg/kg,总有机碳、有机质含量从上游至下游逐渐上升,下游营养物质污染程度严重。模综合评价结果显示:总有机碳所占权重最大,大部分河段底泥质量模糊综合评价等级高于1.6级,自上游至下游污染渐趋严重。The study collected sediment samples in Changchun city section of Yitong River in order to assess the pollution characteristics of the sediment. The water properties,total organic carbon,organic matter,total nitrogen and total phosphorus in sediment samples were tested and analyzed. The fuzzy comprehensive evaluation method was used to evaluate the nutrient pollutants of sediment. The results showed that,the average pH value in target river was 7. 22,which was basically neutral.The average value of total nitrogen and total phosphorus were 622,639 mg/kg,respectively. The content of total organic carbon and organic matter gradually increased from upstream to downstream,and the nutrient pollution level was more serious in downstream. Total organic carbon was the largest weight in fuzzy comprehensive evaluation,and the evaluation level in most parts were more than 1. 6. The pollution showed a trend of getting worse from upstream to downstream.
