Assemblage ) represented the coastal shallow - water environment ; factor 2 ( protelphidium tuberculatum assemblage ) represented the alongshore cold - water current area or cold shallow sea environment ; factor 3 ( elphidium magellanicum assemblage ) represented the sh allow sea ( < 20 - 30m depth ) deposit ; factor 4 ( ammonia ketienziensis assemblage ) represented the shallow - sea water more than 50m depth ; and factor 5 ( buccella frigida assemblage ) represented the colder - water sea environment ; and the distribution of factor load accorded with the character of benthic foraminifer community Q型因子分析揭示ey02 - 2孔5种有孔虫组合，分别对应滨岸盐沼环境、黄海沿岸流冷水分布区、高潮坪浅海沉积环境、水深大于50m的现代浅海环境及较冷的沉积环境。因子载荷的分布与有孔虫群落特征吻合较好。南黄海有孔虫含量? ?水深转换函数关系式有一定的局限性，并不能在南黄海陆架地区推广使用。
