Abstract：Based on the analysis of the carbon and oxygen isotopic characteristics of planktonic foramini-fera and magnetic susceptibility in the columnar samples of TS6 core from the southern part of south-west Taiwan basin of the South China Sea,the climate evolution history of the area since the last degla-ciation was discussed.Oxygen isotope and magnetic susceptibility showed multiple climatic fluctuations since the last deglaciation,and these climatic fluctuations included Heinrich event 1,Bølling-Allerød,Younger Dryas,and multiple cold events in the Holocene.Carbon isotope records showed high produc-tivity of surface seawater in the periods of 16 kaBP～8 kaBP,which was related to the prevalence of winter and summer monsoons.Since the last deglaciation,the overall trend of the magnetic susceptibil-ity was very consistent with that of the winter monsoon.The analysis showed that the change of the magnetic susceptibility was mainly controlled by the strength of the winter monsoon.
