摘要
第四纪地史中,冰川的消长与气候的变化会对植物界产生深刻的影响,因此可以利用研究孢粉的手段来恢复此前的古气候。本文通过对秦皇岛市控制性标准孔的孢粉组合分析,划分出三个孢粉带,六个孢粉亚带孢粉组合,其中孢粉带Ⅰ、Ⅱ了反映了更新世晚期的寒冷干燥的气候特点,孢粉带III反映了全新世中晚期的气候特点。同时通过与深海氧同位素及南极冰芯的对比研究,秦皇岛市植被类型与古气候受冰期-间冰期的影响显著。
In the Quaternary history, glacier growth and decline and climate change had profound effect on plantage, so plaeoclimate can be reconstructed by study of sporo-pollen. This paper analyzed sporo-pollen assemblage in controlled standard hole in Qinhuangdao City, divided it into three sporo-pollen zones and six subzones, of which pollen zone I and II reflected cold and dry climate in late Pleistocene, zone III climate features in mid-late Holocene. By comparing with deep-sea oxygen isotopes and Antarctic ice core, it was found that the paleovegetation type and paleoclimate of Qinhungdao City have been remarkably affected by glacier and interglacier ages.
