A Preliminary Investigation on the Holocene Vegetation Changes From Pollen Analysis in the Gaoximage Section, Hunshandak Sandy Land

浑善达克沙地高西马格剖面孢粉分析及植被演化的初步探讨


为了探讨浑善达克沙地5 000年以来的植被演化过程, 我们对内蒙古正蓝旗境内高西马格湖人工挖掘2.0 m深的剖面进行了较高时间分辨率的孢粉分析,并参考孢粉组合与植被之间的对应关系,得出: 该期的植被和气候演化大致可以划分为3个阶段:阶段 I(约5 010~4 040 aBP),孢粉组合

In order to understand the changes of palaeoclimate and palaeovegetation in Hunshandak sandy land, pollen-spores have been studied from the Gaoximage section (42°57′14.2″ N, 115°22′3″ E, Alt 1 253 m) in the Hunshandak sandy land, Inner Mongolia, Chi
