摘要

摘要/ Abstract摘要:本文对分布在中欧和东欧喜热栎林中的3个栎科联盟(Quercion petaea)、betonnico -Quercion和lathyroa -Quercion进行了比较分析。研究的主要目标是找出欧洲不同地区植物区系和生态差异,并评估植物社会学和层结构的特殊性。基于Bray-Curtis距离矩阵和灵活的beta算法进行聚类分析。采用植物指示法确定生态关系。植物社会学结构的变异是通过不同类型植被的物种份额来研究的。通过比较各层内恒常值最高的树种,研究了各层的结构特征。通过对分异种分布边界的分析,确定了3个分异种群的地理边界。在植物社会学结构中,槲皮属短柔毛类和短足目-槲皮属的种数比例差异最大。中欧和东欧的句法群在主要成层物种的恒常等级序列中表现出显著差异。

Comparative study of Central and Eastern European alliances of thermophilous oak forests (Quercion petraea, Betonico-Quercion, and Lathyro-Quercion) within the temperate zone of Europe
Abstract In this paper we carried out a comparative analysis of three alliances, namely Quercion petraea, Betonico-Quercion and Lathyro-Quercion, which span Central and Eastern European thermophilous oak forests. The main goal was to find out floristic and ecological differences as well as to assess specificities in the phytosociological and layer structure across the syntaxa in different regions of Europe. Cluster analysis was performed based on the Bray-Curtis distance matrix and the flexible beta algorithm. A phytoindication method was applied to determine ecological relationships. Variability in the phytosociological structure was studied by shares of species of different classes of vegetation. The layer structure features were investigated by comparing species with the highest constancy value within each layer. Analysis of the distribution boundaries of differentiating species allowed the geographical boundaries of the three identified syntaxa clusters to be delineated. In the phytosociological structure, the greatest differences were found in the proportion of species of Quercetea pubescentis and Brachypodio-Betuletea classes. The Central and Eastern European syntaxa groups were shown to be significantly different in the constancy-ranked series of major layer-forming species.
