摘要

Surface pollen analysis has been an important tool for refining vegetation history and palaeoclimatic interpretations. In order to study the relationships between vegetation and pollen spectra, modern samples are collected from moss and soil along an elevational gradient in the Lijiang and Dali areas, Yunnan Province. The dominant pollen taxa show relatively high pollen spectra of different vegetation types, although the pollen spectra are distorted by Pinus, which is predominant in almost all pollen spectra of vegetation. This study suggests that the paleo-vegetation could be characterized and reconstructed by pollen types which have relative high value in pollen assemblages from mountainous areas in Yunnan Province.
