摘要
In this paper, five palaeoenvironmental development stages of the palaeolake Taicuo can be recognized: 1) 41.4~26.64 ka (369~319 cm), a warm period in MIS 3a; 2) 26.64~20.48 ka (319~284 cm), a flourishing period of the floras; 3) 20.48~14.60 ka (284~217 cm), the charophytes were less flourishing as the climate became colder and drier, which caused by the decline of water temperature and nutrients; 4) 14.60~10.40 ka (217~125 cm), the charophytes got flourishing again, but the climate was variable in the lake resulted in the frequent water temperature fluctuation; and 5) 10.43~4.5 ka (125~0 cm), the climate in the lake tended to be warm and wet, and the charophytes were in a well-growing state.
