摘要
In accordance with the high resolution pollen record of the Core SA09-090, which was located in the low latitude of the South China Sea, four pollen zones have been distinguished in an ascending order. Inferred from the pollen composition in each zone, the history of vegetation evolution and climate change since 15 000 a B.P. was reconstructed. The result shows that at the early stage of Last deglaciation (15.0～12.5 ka B.P.), the pollen in the research area mainly came from the emerged continental shelf. The vegetation was mainly composed of tropical low-mountain and lowland rainforests. Mangroves bloomed on the coastal area. The temperature was a little lower than that of today, but there was no clear evidence of aridity.
