英文摘要: In this study, paleoclimate signals were extracted from high-resolution sediment records very recently produced from the Mulyoungari swamp on Jeju Island, South Korea and examined to determine the main factors driving late Holocene climate change in East Asia. The high resolution of the Mulyoungari records allows the detection of multidecadal to centennial-scale climate change with various cycles. This enables comparisons with important paleoclimate proxies such as total solar irradiation (ΔTSI) and sea surface temperatures (SSTs) in the western tropical Pacific (WTP). Spectral analyses of pollen and magnetic susceptibility (MS) data identify significant periodicities of 780, 470, 135–145, and 50–70 years. The Mulyoungari swamp responded sensitively to global climate change during the Holocene, showing well known Holocene cycles in the results. Our tree pollen index of warmness (TPIW) shows important late Holocene cold events associated with low sunspot periods such as Oort, Wolf, Spörer, and Maunder Minimum. Comparisons among standard Z-scores of filtered TPIW, ΔTSI, and other paleoclimate records from central and northeastern China, off the coast of northern Japan, southern Philippines, and Peru all demonstrate significant relationships. This suggests that solar activity drove Holocene variations in both East Asian Monsoon (EAM) and El Niño Southern Oscillation (ENSO). In particular, the latter seems to have predominantly controlled the coastal climate of East Asia to the extent that the influence of precession was nearly muted during the late Holocene. © 2017 Elsevier B.V.
