摘　　要：于2012年3月至8月对大神堂贝类养殖区海水中的Cd、Pb、Cu含量进行了分析,结果表明,大神堂贝类养殖区5个站位海水中的Cd含量变化范围在0.104-1.525μg/L之间,Pb含量变化范围在0.120-4.905μg/L之间,Cu含量在0.764-8.429μg/L之间,3种重金属含量符合海水Ⅰ类水质和Ⅱ类水质标准。从重金属污染指数来看,所有调查站位在2012年春季和夏季Pi平均值均小于1,范围在0.209-0.499之间,夏季比春季稍高,说明大神堂贝类养殖区水质状况良好,适合养殖底栖贝类。2012年春季重金属污染指数平均值排序为：Cd〉Cu〉Pb,夏季为：Cu〉Cd〉Pb。From March to August of 2012, Analysis was made to the content of Cd, Pb and Cu of seawa- ter in Dashentang shellfish farming areas. The results showed that in the five sampling sites Cd con- tent were in between 0. 104-1. 525 ttg/L,Pb in between 0. 120-4. 905μg/L and Cu in between 0. 764 -8. 429 μg/L. The water quality was conformed to Grade I and Grade Ⅱ of the national water quality standard. For the heavy metal pollution index analysis：the average of Pi was less than 1 in both spring and summer in the year 2012 in all the sampling sites,ranging between 0. 209 and 0. 499. It is slightly higher in summer than in the spring. The water quality of Dashentang shellfish farming area is in good condition ,and it is suitable for the cultural of benthic shellfish. The order of average pollution index of heavy metal in 2012 were： spring ： Cd〉Cu〉Pb, summer ： Cu〉Cd〉Pb.
