利用在东海北部海域获取的全取芯钻孔DZS1孔202.1 m深沉积物岩芯进行孢粉分析鉴定,通过对松散地层的孢粉研究自下而上划分出了7个孢粉组合带、8个气候期,由孢粉组合带反映出的该区第四纪早更新世以来的气候冷干-温凉湿润-温暖略干-温暖湿润-温凉偏干-温和略干-寒冷干燥-转暖、温暖湿润的气候特点与区域性的气候变化特征比较符合.借助AMS 14C、光释光测年和古地磁测试结果,分析了东海北部海域早更新世以来的气候、环境演化特征,进一步丰富了该海区第四纪孢粉学资料,为该海区第四纪地层划分和对比提供了证据.

7 palynology assemblages and 8 stages about the climatic evolution were distinguished according to the research of spore-pollen from whole core hole DZS1 (202.1 m long) in the northern sea area of East China Sea. Climate stages of Quaternary in this sea area were reconstructed as follows:cold-dry, temperate-cool and moist, warm and slightly dry, warm and moist, temperate-cool and more dry, temperate and little dry, cold and dry, getting warm, warm and moist. These climate fluctuations coincided with the regional climate change. Combined with data of samples AMS 14C, OSL and palaeomagnetic dating, Pliocene evolution features of climate and environment in the northern sea area of East China Sea were discussed. All these provide palynology data and lay the basis on Quaternary stratigraphic classification and correlation in the northern sea area of East China Sea.
