末次冰盛期低海面时南海南北陆架上的植被

An Insight into Paleovegetation on the Emerged Shelf at the Last Glaciation: Pollen Data of the South China Sea 

在探讨孢粉的传播、来源地的基础上，根据南海南北陆坡柱状剖面（１７９４０ ，１７９６４） 的孢粉资料推断末次冰盛期（包括氧同位素３ 期的上部） 低海面时，南北出露的大陆架上生长的植被。末次冰盛期时北部大陆架曾分布以蒿属（Ａｒｔｅｍｉｓｉａ Ｌ．） 为主的草原植被，气候较今日冷且干旱。南部称为“巽他古陆”，曾覆盖热带低地雨林，河口及海岸为红树林，在周围岛屿上高山雨林曾多次向山下迁移，表明当时温度可能较今日低，但湿度没有明显变化。南北大陆架末次冰期时在植被与气候演化上的巨大差异，可能与南部巽他陆架的特殊位置（ 西太平洋暖池）

Vegetation on the emerged continental shelves of the South China Sea (SCS) during the Last Glacial Maximum (LGM) was deduced based on pollen of hemipelagic sediments from the continental slopes and the consideration of pollen transport dynamics and source areas. During the LGM (including the top of Oxygen Isotope Stage 3) the sea level might be more than 100 m lower than that of the present. Consequently, both northern and southern continental shelves of the SCS were exposed. The northern continental shelf was covered by grassland mainly of Artemisia. The climate should be cold and dry, whereas on the southern continental shelf (Sunda Land) was spread tropical lowland rainforest and mangroves were scattered by the river mouths and along the coast. The climate might be cooler than that in the present day, but drop of humidity was not observed.
