摘要
利用中国第24次南极科学考察获得的沉积物样品,对南极普里兹湾表层沉积物中孢粉的含量以及分布特征进行了初步研究。研究结果显示,普里兹湾表层沉积物中孢粉由现代沉积孢粉和再沉积孢粉组成。其中,现代沉积孢粉主要来自南极辐合带以北的大陆或岛屿,风可能是将这些现代花粉长距离携带至普里兹湾的主要载体;根据区内表层沉积物中再沉积孢粉的组分、丰度及分布格局推测,其可能属于近源补给成因,主要来自于普里兹湾沿岸。
Investigations were conducted into the content and distribution of pollen and spores in surficial sediments of Prydz Bay, Antarctic during the 24th Chinese National Antarctic Research Expedition. The results show that the palynological remains in the surface sediments of Prydz Bay consist of modern pollen and redeposited sporopollen. The modern pollen is mainly transported from the continents and islands north of Antarctic Convergence Zone; upper air currents may allow the dispersal of pollen and spores for some thousands of kilometers. The composition of the reworked sporopollen assemblage and its distribution pattern indicate that it may have been supplied from nearby, and has mainly come from the coast of Prydz Bay.
