英文摘要	The South China Sea (SCS), influenced by the tropical East Asian Monsoon (EAM), experiences winter monsoon and summer monsoon shifts in near-surface wind, air temperature, sea-surface temperature, salinity, primary productivity, and other oceanographic conditions. To understand how monsoon seasons influence palynological dynamics and which palynological index could be a reliable indicator of winter or summer monsoons, we studied palynological records of sediment trap samples collected in March-April (winter monsoon season) and July August (summer monsoon season). Fluxes and assemblages of terrestrial pollen and spores, as well as marine dinoflagellate cysts, were investigated using sediment traps in the southwest Taiwan waters of the SCS. The pollen and spores of 109 taxa and dinoflagellate cysts of 53 taxa were identified in 24 sediment trap samples that were collected at 3-day intervals. The average abundance of Pinus pollen was notably higher in March-April at similar to 40%, which was double that in July-August. This trend was associated with transport by the northwest wind in March-April when Pinus pollen are produced by the coniferous vegetation in the South China and Taiwan Island. The pollen abundances of Chenopodiaceae/Amaranthaceae and Compositae seemed to be greatly reduced in July-August, with an opposite pattern observed for Poaceae, Artemisia, Cyperaceae, Typha, and fern spores. Fluvial transport is likely the controlling factor since river runoff intensifies in summer. High relative abundances and fluxes of Poaceae pollen are not indicators of summer monsoons but related to cultivated activities.
