ABSTRACT

A high-resolution pollen-based bioclimatic reconstruction from Bahar Nuur Lake in Inner Mongolia, China, supported by 15 AMS dates, is compared with other records in the Ordos Plateau and stalagmite record from Dongge cave in order to better understand the Holocene climate history in semi-arid East Asian monsoon margin area better. A humid climate prevailed in the Ordos Plateau during 6.3-4.4 ka BP, as indicated by high broadleaf-tree pollen percentages and pollen concentrations. Due to a strong Asian monsoon, the mid-Holocene climatic optimum exhibited a delayed vegetative response on the Ordos Plateau.
