Accordingly, it is important to distinguish the local and regional pollen spectra in terms of the reconstruction of environmental history.

因此，在古环境研究中，区分局部性与区域性花粉谱变化有着重要的意义。

Completely different characteristics of pollen spectra are shown by the pollen records from the Southeast and the northwest of the Qinghai-Xizang Plateau.

全新世青藏高原的花粉记录，反映高原东南部和西北部截然不同的孢粉类型。

The relationship between existing vegetation diversity and its pollen diversity can be used to infer past vegetation diversity from the spectra of fossil pollen.

现存植被与其花粉分布的关系可作为利用化石花粉图谱重建古植被时的参照，因此，理解现存表土花粉分布格局对解释花粉图谱十分关键。
