| 摘 要： |  为了解大亚湾2010—2018年表层沉积物中重金属铜 (Cu)、铅 (Pb)、锌 (Zn) 的时空分布特征及其潜在生态风险，该研究于2010、2012、2015和2018年在大亚湾海域采集表层沉积物并进行分析研究。结果表明，近十年来大亚湾表层沉积物中Cu、Pb、Zn的含量较稳定，未出现明显的增加，3种重金属的空间分布情况大致相同，高值区均集中于澳头至石化区一带的近岸海域。  |

| Abstract: | In order to understand the tempo-spatial distribution characteristics and potential ecological risks of heavy metals (Cu, Pb, Zn) contents in the surface sediments of Daya Bay from 2010 to 2018, we collected and analyzed the surface sediments in Daya Bay in that period. The results show that the Cu, Pb and Zn contents in the surface sediments had been relatively stable in the past ten years without a significant increase. The spatial distribution of the three heavy metals was roughly the same with the high-value areas in the district from Aotou to the petrochemical area.  The Cu, Pb and Zn presented a significant homology, mainly coming from coastal industrial enterprises and marine aquaculture in Aotou area. Their pollution degree showed a descending trend of Zn>Cu>Pb, and the overall potential ecological risk was slight. |
