【摘要】 通过对上海地区三个钻孔更新世地层的孢粉研究,划分出了更新世 9 个孢粉组合带,反映了该区植被演替?气候波动?环境变迁的 9 个阶段,得出该区古气候波动历程为冷凉稍湿→暖热湿润→凉冷稍干→温暖湿润→凉冷稍干→热暖潮湿→凉冷干燥→温暖湿润→凉冷略湿?这种波动不仅可与国内外气候期相对比,而且气候波动曲线与海平面变化相吻合?从而为本地区进行地层年代划分和对比提供了充分的证据,且进一步丰富了本地区孢粉学资料?更多还原

【Abstract】 Nine spore-pollen zones which have been distinguished through the palynological research of pleistocene sediments of 3 cores in the Shanghai region reflect the vegetation succession and climate fluctuation and environmental change. The course of palaeoclimate fluctuation is cold and mild wet →warm and moist→cold and cool and a little dry→warm and moist→cool and cold and a little dry →hot and wet →cool and cold and dry→warm and moist →cold and cool and a little moist. It conforms to the climate of the world and the curve line of the climate fluctuation coincides with that sea level changes. The data of spore-pollen offer the palynological information in the Shanghai region.更多还原
