| 摘 要： | 通过对道孚县第四纪湖积剖面孢粉样分析,根据样品中孢粉百分含量的变化和种类的不同将其划分出3个组合带,并依次论述了其组合特征;另外根据孢粉组合特征分析了该区49.2万a以来的古植被、古气候的变迁与演化。结果表明,该区古植被、古气候经历了3个阶段的演化。

| Abstract: | Based on the analysis of Daofu county quaternary lacustrine section pollen samples,this paper divided them into three different combinations according to the changing percentage of pollens and different kinds of pollens in the samples.Then in this paper,we discussed the characteristics of their assemblage characteristics;analyzed the change and evolution of the palaeo-vegetations and palaeo-climate in this area for 492,000 years according to these characteristics.The results showed that the palaeo-vegetatio... |
