摘　　要：铜在开阔大洋表层水中含量极低,以多种形态存在,具有生物可用性和毒性双重功能。海水中的铜能调节浮游植物的群落结构并影响初级生产力,在全球生物地球化学循环中发挥着重要作用。近30年来,随着样品采集、分析技术的进步,海水中铜的生物地球化学研究得到了飞速发展。综述了铜对浮游植物和微生物的生理生态效应(参与生命过程,与其他金属的相互作用和毒性等),铜在海水中的形态(价态、化学形态、有机配体和生物有效性等),源汇通量(主要源汇过程、通量及同位素组成特征),水平和垂直分布规律和影响因素等。最后,对海洋痕量金属铜的研究方向进行了展望,以期为今后海水中铜的生物地球化学研究提供参考。The concentration of copper is extremely low in the surface water of the open ocean.Copper has multiple speciations and the dual functions of bioavailability and toxicity.Copper in seawater can regulate phytoplankton and affect the primary production,playing an important role in marine biogeochemical cycles.With the advancement of sample collection and analysis techniques,the biogeochemical research of copper in seawater has developed rapidly in the past 30 years.Here,we provide a comprehensive review on marine copper biogeochemistry.Firstly,we summarized the physiological and ecological effects of copper on phytoplankton and microorganism.For example,copper can participate in the life processes of phytoplankton and microorganism,interact with other metals and have the toxicity.Secondly,we reviewed the chemical forms of copper in seawater(such as valence states,speciations,complexation with organic ligands and bioavailability).Finally,we summarized the sources and sinks of copper in the ocean(and the fluxes and isotopic composition),the horizontal and vertical distribution of copper in seawater,and factors influencing these were also reviewed.We suggest future research topics dealing with copper biogeochemistry to provide new insights into the role of copper in seawater and biological cycles.
