项目摘要

Early Carboniferous (Mississippian) floras are rather poorly known in comparison to Late Devonian and especially in comparison to Late Carboniferous (Pennsylvanian) floras, because Lower Carboniferous floras are comparatively rare. Although much work has been done in recent years on anatomically preserved material, the classification of Lower Carboniferous compression remains is still very problematic. Although comparisons of floras from various parts of Europe are strongly hampered by the lack of a uniform nomenclature and statistical data are not available yet, within western and central Europe a regional differentiation into different types of floral assemblages seems to exist, at least during the Visean. Similar patterns have been observed in palynological associations. The exact reasons for this differentiation are not clear. The aims of this study are: (1) the establishment of a uniform classification of Early Carboniferous plants, preferably based on whole plant taxa and including biological criteria, (2) once a good taxonomic framework has been established, comparisons between the various Lower Carboniferous occurrences in Germany and other parts of Europe will be made. This project should contribute to a better understanding of regional and ecological differentiation of floras during a time interval that is the advent of the period characterized by the largest accumulation of plant biomass in Earth history.

早石炭世（密西西比纪）植物群与晚泥盆纪相比，尤其是与晚石炭世（宾夕法尼亚纪）植物群相比，知之甚少，因为早石炭世植物群相对稀少。尽管近年来对解剖学保存的材料做了大量工作，但下石炭统挤压遗迹的分类仍然存在很大问题。虽然来自欧洲各地的植物区系的比较受到缺乏统一命名法和统计数据的严重阻碍，但在西欧和中欧，似乎存在不同类型的植物区系组合的区域分化，至少在维西安时期。类似的模式也在孢粉学群丛中观察到。这种区别的确切原因尚不清楚。本研究的目的是：（1）建立一个统一的早石炭世植物分类，最好是基于整个植物分类群和包括生物学标准，（2）一旦建立了一个良好的分类框架，将在德国和欧洲其他地区的各种下石炭世之间进行比较。该项目应有助于更好地了解在地球历史上植物生物量积累最多的时期到来这段时间内植物区系的区域和生态差异。
