SPOROPOLLEN AND ALGAE RESEARCH OF CORE B106 IN THE NORTHERN SOUTH CHINA SEA AND ITS PALEOENVIRONMENTAL EVOLUTION

Based on the high-resolution sporopollen and algae research of the sediments from core B106 in the northern South China Sea, three sporopollen zones have been distinguished in ascending order:
Zone 1(294~194 cm):Pinus-Quercus(evergreen)-Gramineae-Polypodiaceae-Pterdium-Dicranopteris.
Zone 2(194~94 cm):Pinus-Quercus(evergreen)-Polypodiaceae-Pteridium-Dicranopteris.
Zone 3(94~4 cm):Pinus-Polypodiaceae-Pteridium-Quercus(evergreen)-Dicranopteris.
These sporopollen zones reflect three stages of vegetation, climate and paleoenvironment evolution of the northern South China Sea since 11 000 years ago. Combined with AMS ¹⁴C dating, the sporopollen and algae data can be a scientific evidence for stratigraphic division and reconstruction of paleoclimate and paleoenvironment in the South China Sea.
