摘要 考虑了末次间冰期希腊大陆植被发育的区域变异程度。三个花粉序列——约阿尼纳（希腊西北部）、特纳吉·菲利普（希腊东北部）和科派斯（希腊中部）——都位于不同的环境背景下，延伸到最后一个间冰期。对末次间冰期期间这三个地点的植被历史的研究揭示了当地气候条件的影响，西北地区是封闭的混交林，向东部和南部逐渐变得更加开放和多样化。然而，所有三个序列在某些类群的扩展方面都包含许多相似的趋势。此外，它们还表明存在两步的晚冰期、间冰期第二部分的短暂森林减少以及间冰期末期树木种群的最终小幅扩张。与其他欧洲记录的比较显示了许多共同特征，但也表明与希腊遗址的特定环境设置一致的差异。
Abstract The extent of regional variability in vegetation development in mainland Greece during the last interglacial is considered. Three pollen sequences – Ioannina (northwest Greece),Tenaghi Philippon (northeast Greece) and Kopais (central Greece) – all located in different environmental settings, extend into the last interglacial. Examination of the vegetation histories of the three sites during the last interglacial reveals the influence of local climatic conditions with closed mixed forests in the northwest, becoming progressively more open and less diverse farther to the east and south. All three sequences contain a number of similar trends, however, in the expansion of certain taxa. In addition, they also show the presence of a two-step late glacial interval, a short episode of forest reduction in the second part of the interglacial and a final small expansion of tree populations at the very end of the interglacial. Comparison with other European records shows a number of common features, but also suggests differences consistent with the particular environmental setting of the Greek sites.
