| 摘 要： | 本文使用孢粉图式、最优分割、对应分析和Q型聚类分析方法，将福建霞浦No.1孔的孢粉划分为8个孢粉组合带，并由此推论出8个植被演替阶段。依据对应分析结果和一系列热力学计算公式，本文估算了该孢粉所反映的古气候因子。它们包括年平均温度、相对温度、绝对湿度、水汽压、年蒸发量、干燥度、年降水量。并依据之些古气候因子，认为该孔孢粉反映的该地区晚第四纪古气侯有7个阶段。

| Abstract: | Based on pollen diagram, optimum segmentation, corresponding analysis and clusteranalysis,this paper classifies the pollen-spores of Core No. 1 from Xiapu, Fujian, into eightpollen zones, from which eight vegetational stages are induced. On the basis of the results ofcorresponding analysis and formulas of thermodynamics, the paper calculates thepaleoclimatic factors of this core, including annual average temperature, relative humldlty, absolutehumidity, vapour pressure,annual evaporatlonal ability,dryness index and annualprecipitation. According to these paleoclimatic factors, the Late Quaternary paleoclimate of thisregion includes seven stages, |
