According to a core from Tianchi Lake,Liupan Mountain in Loess Plateau sediment,fossil pollen assemblages,magnetic susceptibility(MS)and color scale were measured based on reliable Abies leaf macrofossils radiocarbon chronology.We recovered a very good high-resolution mid-late Holocene climate change achieve for the transition area of the East Asia monsoon region and northwest arid region.The results show that the basic climate background was in agreement with the records from cave records in monsoon regions in eastern China.Besides,it shows more detailed records in abrupt climate change.
