Based on the data of spore-pollen, palaeomagnetism and optically stimulated luminescence from Hole HB1, which is located at the Balizhuang village in Huanghua City, eastern Hebei Province. The evolution of palaeovegetation in the west coast of Bohai Sea since Quaternary is found not only to be impacted by the climate change but also dominated by the sediment environment. Although the sampling density of spore-pollen analysis at this drilling hole is the highest in the holes on the coastal plain at present, but there is no continuous rich spore-pollen sequence, possibly because that Hole HB1 located at a higher place and impacted by the river sediments environment. Thus, the spore-pollen stratigraphy in the whole Quaternary cannot be reflected through one borehole study in the plain area.
