摘　　要：南沙群岛永暑礁小泻湖南永 3井的高分辨率岩心系统揭示了环礁泻湖近 16 82 a BP来的沉积柱样的氨基酸组成和含量 ,其垂直变化同该岩心的有孔虫丰度、微型腹足类丰度和δ1 8O含量的垂直变化基本一致 ,反映了沉积环境及其变化。By high resolution materials from the core of Nanyong 3 well,deposited during the last 1682 years,the composition and contents of amino acid in the sediment column in the Yongshu atoll lagoon are systematically demonstrated.Its vertical changes are in accordance with those of foraminifera abundance,microgastropod abundance and oxygen isotope contents in the same core,which reflect the depositional environment and changes.From the analysis we can see that climatic changes in coral reef region of the Nansha Islands are synchronous with those in China and even globally the same.
