摘　　要：通过监测蒲河水质的部分指标,包括底泥的pH、有机质含量、重金属(主要铜、锌、铅、铬、镉)等,使用OPT-MA3000全谱等离子体直读光谱仪对重金属含量进行测定,并运用模糊综合评价方法对蒲河水体底泥进行了综合评价。结果发现:底泥中有机质含量比较低;蒲河水体底泥状况属于污染严重级别;Cr的污染明显超标;蒲河水体底泥受到了Cr、Pb、Zn、Cu这4种重金属的复合污染。This paper mainly monitors and evaluates the sediment quality of Pu River which flows through Shenbei new district in Shenyang city,in terms of indicators of the water quality of Pu River,including pH,organic matter content,heavy metals（Cu,Zn,Pb,Cr,Cd）,etc.in sediment.Contents of heavy metals were measured by OPTMA 3000.The sediment quality of Pu river was evaluated by using fuzzy comprehensive evaluation.It was found that the organic matter content in sediment is relatively low,sediment in Pu River was seriously polluted,especially Cr pollution is significant,and sediment of Pu River is polluted by the combined pollution of Cr,Pb,Zn and Cu.
