Artificial islands construction can significantly influence the spatial distribution of heavy metals in inshore sediments. In this study, the distribution and contamination of heavy metals (Cd, Co, Cr, Cu, Ni, Pb, Zn, As and Hg) in inshore sediments of the Longkou Bay and artificial island adjacent areas were investigated in 2013 and 2014, respectively. Results showed that the contents of heavy metals increased in the Longkou Bay and decreased in the west of the artificial island in 2014 compared with 2013. The contamination and potential eco-risk of heavy metals in the sediments were higher in 2014 than those in 2013. Cd and Hg showed a high potential eco-risk in LK02, and other metals were in the lower level. The results indicated that after the construction of artificial islands in the Longkou Bay, the contamination and eco-risk of heavy metals in the sediments markedly increased in the Longkou Bay.

人工岛的建设会严重影响近海沉积物中重金属的空间分布。本研究分别于2013年和2014年调查了龙口湾近海沉积物和人工岛附近地区重金属（Cd，Co，Cr，Cu，Ni，Pb，Zn，As和Hg）的分布和污染。结果表明，与2013年相比，2014年龙口湾的重金属含量有所增加，而人工岛西部的重金属含量有所减少。2014年沉积物中重金属的污染和潜在的生态风险高于2013年。镉和汞在LK02中显示出很高的潜在生态风险，而其他金属则处于较低水平。结果表明，在龙口湾建设人工岛后，
