对伶仃洋沉积物表层中的有孔虫生物群与埋葬群进行了比较分析 ,有效地分辨　　出河口湾内拦门沙区的高速沉积带、深槽里的有孔虫异地埋葬分子、东、西槽内陆架咸水作用的差异以及沉积物不同搬运方向等 .证明用有孔虫生物群与埋葬群的对比分析可判释出沉积动力环境的更细微的差别和变化 ,较单纯据死有孔虫群的分析效果要好 . A comparative analysis of foraminiferal biota and burial groups in the surface sediments of the Lingdingyang Bay is made to effectively distinguish the high-speed sedimentary zones of the estuary sandstorm in Hekou Bay and the foraminifera burial in the deep trough, east and west Differences in saltwater function of the inland shelf and different sediment transport directions, etc. It is proved that the comparison and analysis of the foraminiferal biota and the burial group can explain the more subtle differences and changes of the sedimentary dynamic environment, Swarm analysis is better.
