Abstract The exploration of Lateglacial vegetation history in Schleswig-Holstein is elaborate and comprehensive. Despite being one of the most studied areas, regarding to the Lateglacial, no biostratigraphy covering the complete Lateglacial and Early Holocene periods without hiatus have so far been recovered. In this paper we present a biostratigraphy of the Nahe paleolake, therewith intending to deal with this desideratum. The special strength of the presented sequence is expressed in the fact that these are the only palynologically investigated sequentially annual laminated limnic sediments of the Lateglacial in Schleswig-Holstein. These laminated sediments, as well as radiocarbon dating of botanical macrofossils and three geochemically confirmed cryptotephra layers (Laacher See Tephra, Vedde Ash and Saksunarvatn Ash), provide excellent chronological control and allow for a Europe-wide correlation. Particularly important is a complete discussion of the vegetation history and the spatial proximity to Late Paleolithic sites, which renders it possible to evaluate potential human–environment-interaction long before classical palynological human indicators occur.

序列完成——对德国石勒苏益格-荷尔斯泰因州 Nahe 古湖的顺序层状湖相沉积物中记录的晚冰期/早全新世环境变化进行孢粉学调查

摘要 对石勒苏益格-荷尔斯泰因州晚冰期植被历史的探索是详尽而全面的。尽管是研究最多的地区之一,但关于晚冰期,迄今为止还没有恢复到没有间断的完整的晚冰期和早全新世时期的生物地层。在本文中,我们介绍了那河古湖的生物地层学,并打算处理这一需要。这些序列是石勒苏益格-荷尔斯泰因州晚冰期的唯一按孢粉学研究的年度层状湖泊沉积物,这一事实表明了所呈现序列的特殊强度。这些层状沉积物,以及植物大型化石和三个地球化学证实的隐藻层(Laacher See Tephra、Vedde Ash 和 Saksunarvatn Ash)的放射性碳测年,提供出色的时间顺序控制并允许欧洲范围内的相关性。特别重要的是对植被历史和与旧石器时代晚期遗址的空间接近度的完整讨论,这使得在经典孢粉人类指标出现之前很久就可以评估潜在的人类-环境-相互作用。
