Abstract:

A new pollen record from the Huguangyan Maar Lake(110017'E,2109'N) in the Leizhou Peninsula,Guangdong Province,China,provides information on vegetation and climate changes since the last glaciation.Six major significant changes in pollen associations indicate the history and the process of vegetation successions,those are the southern subtropical evergreen monsoon forest,middle subtropical evergreen and deciduous broad - leave dforest,southern subtropical evergreen monsoon forest,middlesubtropical evergreen - deciduous broad - leaved and conifer mixed forest,tropical seasonal rain forest,and the semi-evergreen seasonal rain forest.The pollen record suggests that the temperature dropped 4-6 ℃ during the coldest epoch of the last glaciation than that of today.The climate in early Holocene was drier in this region.
