摘　　要：以2009年9月岚山港临时海洋倾倒区表层沉积物监测数据为基础,分析了该倾倒区海域表层沉积物重金属污染分布情况,发现该倾倒区海域表层沉积物重金属Cu、Pb、Zn、Cd、Cr、Hg污染分布大致表现为倾倒区范围内含量高,倾倒区外围含量低的趋势,可能是疏浚物的倾倒造成的这种分布特征。分析了岚山港临时海洋倾倒区表层沉积物重金属含量与有机碳、粒度的相关性,发现重金属含量与有机碳含量具有较高的正相关性,其中Cr与有机碳含量显著相关(P<0.01),重金属含量与粒度(沉积物黏土含量)呈正相关性。Based on the monitoring data of surface sediment in September 2009, the distribu-tion of surface sediment heavy metals contamination of Temporary Ocean dumping site in Lanshan Port were analyzed. The content of heavy metals （Cu, Pb, Cd, Zn, Cr, and Hg：） were high in central dumping area while low in the outside, which showed that dredged ma-terial dumping was possibly the main source of pollution. By analyzing the relationship be- tween surface sediment heavy metals pollution and organic carbon, salinity, particle size, the results showed that there was a positive correlation between sediment heavy metals pollution factors and organic carbon, particle size, while there was significant correlation between Cr and organic carbon （P〈O. 01）.
