本文以闽南沿海典型河口海域为研究对象，以厦门湾九龙江口和泉州湾为例，对表层沉积物中重金属的含量、重金属沉积规律、营养盐含量水平和分布特征进行了研究，对厦门湾九龙江口和泉州湾环境质量进行了定量和定性描述，并对重金属和营养盐进行了潜在的风险评价，得到了以下的结果： （1）厦门湾九龙江河口海湾表层沉积物中重金属含量基本符合一类海洋沉积物质量标准，铅和镉在个别站位含量超标，有机碳含量均符合一类海洋沉积物质量标准；泉州湾有机碳、铬、汞、铅、锌的含量均符合一类海洋沉积物质量标准，镉在个别站位超标；泉州湾芦苇中的重金属含量普遍较低，仅在湾内的西滨处呈现较高水平；蟹类对重金属具有较高的摄取量，其中铅在河流入...In this paper, Jiulong river estuary and Quanzhou bay of Minnan area were investigated. We have studied the contribution and contents of heavy metals in the surface and nutrient elements in Jiulong river estuary and Quanzhou bay. The environmental quality was quantitatively and qualitatively described and discussed in two main aspects. The eco-enviromental effects of heavy metals and nutrient elem...学位：理学硕士院系专业：海洋与环境学院海洋学系_海洋化学学号：2242006115229
