通过对上海地区高桥G2孔晚第四纪地层中孢粉的研究,将高桥G2孔自下而上划分出了6个孢粉组合带,并结合临近的斜土路2号孔和人民广场钻孔的孢粉研究资料,恢复了该地区植被演替、气候波动的六个阶段,这种气候的波动不仅与世界性气候变化一致,而且其波动曲线与海平面变化曲线也是相吻合的。
Through the study on the sporopollen in Quaternary of G2 hole in Takahashi, Shanghai, the G2 hole of Takahashi was divided into 6 sporopollen belt from bottom to top, and combined with adjacent No. 2 Xietu Road and People’s Square The borehole pollen research data restored six stages of vegetation succession and climate fluctuation in this area. The climate fluctuation is not only consistent with the global climate change, but also its fluctuation curve is consistent with the sea level curve.
