Abstract:According to the postglacial sporo-pollen distribution from the typical borehole CSJA6 in the paleo-incised valley of the Yangtze River Delta, combining with the forams analysis and AMS 14C dating of 6 samples, 3 sporo-pollen assemblages with time calibration from below were established: I. Quercus-Lipuidambar-Artemisia-Polypodiacea assemblage, belonging to the early Holocene; II. Quercus-Castanopsis-Cyperaceae-Pteris assemblage, belonging to the early-middle Holocene; III. Quercus-Ulmus-Artemisia-Polypodiacea assemblage, belonging to the middle-late Holocene. These three sporo pollen assemblages reflect the paleoclimate evolution process as cold and dry-hot and wet-warm and dry, which is consistent with the climate environment of China. This research is basically identical with the results of previous studies in this region.
