中文摘要：

根据近几十年来发表的关于渤海沉积物中Cu元素含量与分布的相关研究结果,编制了渤海表层沉积物中Cu含量分布图,系统分析了渤海表层沉积物中Cu含量在1980S年代和2000年以后的含量分布特征及影响其分布的相关因素,分析结果表明：近几十年来渤海表层沉积物中Cu含量有增加趋势,其分布受河流的输入影响明显,其次还受控于表层沉积物组成特征和区域背景值。

英文摘要：

Copper is an element widely distributed in the nature.It＇s also widely used in modern industry,which leads to the increase in Cu levels in various environments and poses great risks to the environment quality.In this paper,the Cu distribution pattern in sediments of the Bohai Sea is discussed with the support of the distribution maps of Cu in the surface sediments during the 1980＇s and 2000＇s.Additionally,the relationships between the distribution pattern and terrestrial inputs are analyzed.
