摘　　要：根据2002年6～7月对象山港进行生态调查所获得的资料，评价了象山港水域的沉积物类型变化和沉积环境质量状况，结果表明；与20世纪80年代相比，象山港沉积物类型已发生了较大的变化，由80年代的粉砂质粘土、粘土质粉砂、粘土-粉砂-砂及砾砂4种沉积物类型变为2002年的粉砂质粘土、砂、砂-粉砂、粘土-砂、砂-粉砂-粘土、中细砂、中砂7种沉积物类型。象山港沉积物的质量良好，底质中总氮的含量较高，普遍出现超标现象；部分测站的多氯联苯（PCB）略有超标，各测站总磷硫化物、有机质、石油类等指标均符合一类标准。Based on the monitoring data on the Xiangshangang Bay in 2002, the assessment and analysis for the seamud quality has been made. The results indicated that the type of seamud has been more changed since 1980. The quality of surface sediments was in middle level, the content of nitrogen was high and went beyond the standard widely, the content of PCB in 9 and 16 stations went beyond the standard. The total nitrogen, total phosphorus, organic carbon, sulfide, oil hydrocarbon below the standard.
