摘要
本文选择福建沿海中段莆田、惠安、泉州等地,晚更新世以来10个露头剖面沉积物样品进行孢粉研究,得出本地区晚更新世以来的10个孢粉组合。根据14C测年结果,划分了各孢粉组合所相应的地质时代,探讨了不同地质时代孢粉组合所反映的古植被、古气候。
From sections at middle Fujian coast, ten sporo-pollen assemblages have been obtained, and the Late Quaternary paleovegetation and paleoclimate restored, and a suitable geologic time for palynological assemblages discussed.The sporo-pollen assemblages of the Late Quaternary in this region are as follows:Whrm interglacial subperiod: Gramineae-Cyperaceae-Typha-Querc (evergreen) palynological assemblage revealing a warm and moist climate.Wurm interglacial subperiod: Gramineae-Cyperaceae-Polypodiace (evergreen)palynological assemblage revealing a temperate and semi-moist climate.Wurm glaciod period (Ⅱphase): Artemisia-Gramineae-Cupressaceae palynological assemblage revealing a cold and dry climate.From whrm glacial period (ⅡPhase) to pre-Boreal: Gramineae-Cyperaceae Quercus-Pinus Palynological assemblage revealing a temperate-cool and slightly dry climate.Boreal: Quercus-Pinus-Gramineae-Artemisi Palynological assemblage revealing a warm and a little dry climate.Atlantic: Castanopsis-Quercus (evergreen )-Rhizophoraceae palynological assemblage revealing a hot and wet clinate.Sub-Boreal:Pinus-Quercus (evergreen) Palynological assmblage revealing a warm and a little dry climate.Sub-Atlantic:Quercus (evergreen)-Castanopsis-Castanea-Rhizophoraceae palynological assemblage revealing a hot and miost climate.Sub-Atlanic: Gramineae-Potamogetonaceae-Querc (erergreen )-Hymenophyllaceae palynological assemblage revealing a warm and moist climate.
