| 摘 要： | 对南海149站和323站深海柱状剖面进行了孢粉与藻类研究,根据孢粉成分的变化将南海149站从下至上划分了4个孢粉组合带,依次为:1带:Pinus-Quercus(常绿)-Umbellferae-Gramineae-Pteris孢粉带(407～270cm);2带:Dacrydium-Quercus-Cyathea-Pinus-Polypodiaceae孢粉带(270～105cm);3带:Pinus-Polypodiaceae-Quercus(常绿)-Pteridium孢粉带(105～30cm);4带:Gleditsia-Cyathea-Pinus-Polypodiaceae孢粉带(30～0cm)。323站也划分了4个孢粉带,与149站进行了比较研究。并相应恢复了南海东部7.5万年以来4个植被、气候、古环境演替阶段,结合氧同位素测年资料,对149站和323站柱状地层时代划分作了讨论,为南海古植被、古气候、古环境演变研究提供科学依据。

| Abstract: | Palynological research of deep-sea sediments in the South China Sea has been carried out. Based on the sporopollen and algae assemblages of the deep-sea sediments in cores 149 and 323 in the South China Sea,four sporopollen zones of core 149 have been distinguished in ascending order:Zone 1(407~270 cm):Pinus-Quercus(evergreen)-Umbellferae-Gramineae-Pteris;Zone 2(270~105 cm):Dacrydium-Quercus-Cyathea-Pinus-Polypodiaceae;Zone 3(105~30 cm):Pinus-Polypodiaceae-Quercus(evergreen)-Pteridium;Zone 4(30~0 cm):Gledit... |
