中文摘要：

通过综合分析东海陆架南部EA05岩心上部30m的岩性、有孔虫丰度和一些特征的地球化学参数，探讨了该段岩心的气候地层划分。该段岩心可依次划分为末次盛冰期（30～11．85m）、冰消期（11．85～5m）和冰后期（5～0m）地层。末次盛冰期时气温低。研究区水深浅。沉积物中有孔虫丰度很低，且大多数热带浮游有孔虫种属消失，此时陆源物质输入量较大，沉积物中有机质含量高。黑潮对东海陆架南部影响小。随着冰消期以来气温回升，海面上升，研究区水深增大。岩心中有孔虫丰度急剧增加；陆源物质输入量减少，沉积速率降低。大约在16kaB．P．左右，黑潮重新开始对东海南部陆架产生影响。在EA05岩心的6～5m，3．4～3．0m和1．4～1．2m处分辨出了3个冷事件，可能分别对应于YD事件、8．2kaB．P．冷事件和3．8kaB．P．新冰期Ⅲ。反映出该地区冰消期和冰后期气候波动较大。

英文摘要：

Based on the analysis of lithology, foraminifera abundance and typical geochemical indexes in the upper 30 m of core EA05, which was taken from the southern part of the continental shelf of the East China Sea, it is found that this portion can be divided into three strata. The 30-11.85 m section is composed of the Last Glacial Maximum sediment; the 11.85- 5 m section the deglacial sediment and the 5-0 m section the postglacial sediment. During the Last Glacial Maximum the water depth in the study area was shallow; the abundance of foraminifera was very low, and most genera of tropic planktonic foraminifera disappeared. But the terrestrial material input was very high, along with abundant organic material. The influence of the Kuroshio Current on the southern continental shelf of the East China Sea was weak at the time. During the deglacial and postglacial periods, with the increase of air temperature and sea level, the terrestrial flux and sedimentation rate decreased while the foraminifera abundance increased with the influence of the Kuroshio Current becoming stronger. The Kuroshio Current began to influence the southern part of the East China Sea continental shelf at about 16 ka B. P. Three obvious cold climate events are distinguished at 6-5 m, 3.4-3.0 m and 1.4-1.2 m of core EA05, they probably correspond to the Younger Dryas, the 8.2 ka B.P. cooling event and New Ice Age Ⅲ respectively, indicating climate fluctuation during the deglacial and postglacial periods.
