| 根据2012年3月、5月、8月、11月表层沉积物调查资料，分析了双岛湾附近人工鱼礁区表层沉积物重金属的分布特征，并采用潜在生态风险评价法对重金属的生态危害进行了评价。结果表明：（1）研究海域表层沉积物中重金属含量较低，全部测站Cu、Zn、Pb、Cd、Hg、As的含量符合《海洋沉积物质量》（GB 18668-2002）第一类标准的要求；（2）表层沉积物中重金属的分布较为规律，除Hg含量站间差异不明显外，鱼礁区内站点的Cu、Zn、Pb、Cd、As重金属含量低于周边海域；（3）表层沉积物中重金属含量的月际变化比较明显，以8月最高、3月最低；（4）双岛湾附近海域重金属污染程度处于低级水平，且总体潜在生态危害处于轻微水平。

| 英文摘要: |
| Based on the investigation of surface sediments in the artificial reef area near Shuangdao Bay in March, May, August and November of 2012，the distribution characteristics of heavy metals in surface sediments were analyzed and the ecological risk was assessed by the method of potential risk assessment. The results showed that the average contents of Cu、Zn、Pb、Cd、Hg、As in the artificial reef area were in accordance with the first class standard of the national standard of marine sediment quality(GB18668-2002). In the study area there was a regular distribution of heavy metals, and the contents of heavy metals were lower than those in the neighboring artificial reef area except Hg, which had no obvious difference from that in the neighboring area. Monthly variations were observed in the contents of heavy metals with the highest value in August and the lowest in March. Therefore, the heavy metals pollution around Shuangdao Bay was low and the potential ecological risk of these heavy metals in this area was slight.
