中文摘要：

以2011年洋浦港近岸海域表层沉积物的调查资料为基础，选择2种评价方法（地积累指数、潜在生态危害指数）来了解该区域沉积物中重金属含量的分布特征、污染状况并进一步分析评价。结果表明，洋浦港近岸海域沉积物重金属含量相对远岸海域明显增高，可能已受到陆源污染的影响；洋浦港附近海域表层沉积物重金属含量都符合海洋沉积物质量一类标准，大部分海域沉积物属无污染，仅部分样点沉积物中Cd、Pb受中度污染；洋浦港附近海域重金属潜在生态危害较国内其它港区轻，不存在重金属潜在生态危害，典型重金属潜在生态危害大小顺序依次为Pb、Hg、Cd、CU、Zn。

英文摘要：

Based on the survey data from 2011 for the surface sediments near Yangpu Port, potential ecological risk index and geo-accumulation index are calculated to evaluate heavy metals pollution in the area. Results show that the contents of heavy metals in surface sediments of Yangpu Port inshore are significantly higher than that of its surrounding, may have been the impact of land-based sources of pollution. The contents of heavy metals in all sites are all belonging to Class I ; Most areas were not polluted by heavy metals, except for sam- piing sites Z14, Z15, and Z16, where contents of Cd, and Pb are slightly exceed; The results also reveal that the Yangpu Port and its surrounding sediments have no potential ecological risks for the time being. The order of potential ecological risks is Pb〉Hg〉Cd〉Cu 〉Zn.
