摘 要：We obtained a sedimentary profile from Taiwan’s Toushe *** 12 AMS 14 C samples,we established a reliable stratigraphic *** and charcoal analysis revealed four stages of vegetation,fire and climate between 6.3-1.3 cal ka *** 6.2-4.6 cal ka BP,was a warm and wet period with subtropical evergreen broad-leaved forest and infrequent *** 4.6-3.0 cal ka BP,the climate became cooler and drier with forest declining and regional fires becoming more *** 3.0-2.1 cal ka BP,the EASM continued to weaken,leading to a cooler and drier climate with alpine meadow development,and the dry climate causing high-frequency *** 2.1-1.3 cal ka BP,the climate became warmer and wetter,forest developed and low-levels of of human activity began to impact the *** in climate were closely related to the change of EASM and ENSO.
