| Abstract: | Through the systematic palynological study of two drill holes from Luyangpu Plain, seven sporopollen assemblages have been obtained, and the Holocene paleovegetation and paleoenvironment in Pingtan Island have been restored. The stratigraphical division and correlation, as well as sea level changes during the Holocene in this area have been also discussed.The sporopollen assemblages in ZK417 drill hole can be divided into 3 zones in ascendent order: Zone 1: Polypodiaceae-Quercus (evergreen) palynological zoneZone 2: Castanopsis-Quercus (evergreen) palynological zoneZone 3. Quercus (evergreen)-Castanopsis palynological zoneThe sporopollen assemblages in ZK7621 drill hole can be divided into 7 zones from bottom to top:Zone 1: Pinus-Rhizophoraceae-Gramineae palynological zoneZone 2: Gramineae-Cyperaceae-Chenopodiaceae palynologieal zoneZone 3: Rhizophoraceae-Pinus-Gramineae palynological zoneZone 4: Gramineae-Cyperaceae-Polypodiaceae palynological zoneZone 5: Polypodiaceae-Gramineae-Cyperaceae Palynalogical zoneZone 6: Gramineae-Cyperaceae-Rhizophoraceae-Quercus (evergreen) palynological zoneZone 7: Gramineae-Cyperaceae-Rhizophoraceae palynological zone. |
