摘　　要：以重金属污染严重的江西乐安江表层沉积物为对象，利用热力学相平衡分配法（ＥｑＰ）和相关基础数据库，研究探讨了该流域沉积物中重金属污染的数值型质量控制基准（ＳＱＣ）．结果表明，铜矿采矿活动导致某些江段沉积物中铜实际污染程度远高于相应的ＳＱＣ水平．另外，由于沿江中、小工矿企业废水的随意排放，同样造成附近沉积物中铅、锌、铬等重金属含量不同程度地超出各自的基准数值．此ＳＱＣ的建立为制订该流域沉积物质量管理标准（ＳＱＳ）及污染治理措施提供科学依据．Based on equilibrium partitioning approach (EqP) and CERP DBMS database, the preliminary surface sediment quality criteria (SQC) for heavy metals in the Lean River were developed. The numerical SQC indicated that mining activities of Dexing Copper Mine caused the level of copper contamination much higher than the corresponding SQC value within the specific sections along the Lean River. In addition, release of wastewater from some factories anong the bank also led to increases in concentrations of lead, zinc and chrome, superior to their SQC to different extent. Therefore, it is urgent to link the SQC with the feedback from local economic conditions and social benefits, so that the sediment quality standards (SQS) can be established, and remediation program can be performed.\
