Abstract
Climate fluctuations during the Last Glacial Maximum have been a hot topic recently. Based on fern spores, pollen and algae records of the first hard clay layer from HM core,three palynomorphs assemblages were recognized and climate conditions during the LGM were discussed. Palynomorphs assemblages 1 and 3 show that mixed conifer broadleaf forest developed, indicating relatively warm and wet climate conditions,while palynomorphs assemblage 2 shows that vegetation was almost absent, indicating a cold climate.
