Abstract
Sediment samples were collected from the south slope of the Taishan Mountain for age dating and pollen studies in order to define the paleo-climate pattern during the last glacial period of the Quaternary. Dating data show that the sediments were formed 30.54 + 2.59kaB.P, approximately during the last glacial maximum. Palynological Assemblages were dominated by the cold coniferous species of "Selaginella + Artemisia + Chenopodiaceae" assemblage with "Pinus + Selaginella + Artemisia + Chenopodiaceae" as the major population, indicating a cold climate. Compared the modern temperature and precipitation at the Taishan Mountain with the current climate at Tianshan, Changbai and Lao Mountains, it is inferred that the temperature at the top of Taishan Mountain could be as low as -11.3 to -4.3℃, with high rainfall during the last glacial period.
