摘　　要：在飞云江河口设点采集表层沉积物进行分析,研究表明TN、TP、OM平均含量高于其他江河湖库,TN评价为中度污染,TP为重度污染,As为轻度污染,Cu、Zn、Cd、Cr、Pb、As平均含量高于土壤环境背景值,部分元素高于其他区域实测值,TN、TP与OM没有相关性,Cr与Cu、Pb之间、Cd与Zn、As有着正相关关系,可能具有相近的来源。The surface sediment was collected at the Feiyunjiang River estuary.The study showed that the average content of TN,TP,and OM was higher than that of other rivers,lakes,and reservoirs.TN was evaluated as moderate pollution,TP as severe pollution,and Asas mild pollution.The average content of Cu,Zn,Cd,Cr,Pb,and As was higher than the soil environmental background value,and some elements were higher than the measured values in other regions.TN,TP,and OM were not correlated,but Cr was positively correlated with Cu,Pb,Cd with Zn,and As,which may have similar sources.
