摘要

欧洲半干草地是北半球物种最丰富的植被类型之一,是森林-草原带生境马赛克的重要组成部分。然而。目前还没有对这些草原的组成变化和植物社会逻辑分类进行综合评价。为了进行句法修正,我们使用了来自中欧和东欧的34,173个植被样地记录的数据集。使用EuroVegChecklist中列出的诊断物种将其分配到Fesiuco-Bromeiea类。为了确定该目的诊断种,我们对整个数据集使用了TWINSPAN分类。在整个数据集中,15449个片段被分配给了Brachypodietalia pinnati目。这相当于半干草原。该子集再次使用TWINSPAN进行分类。建立了下列联盟的正式定义:mesbroromion erecti,Cirsio-Brachypodion pinnati(包括Fragario-Trifolion montani)。草皮草-雪条草、黄皮草-毒叶草、绿皮草-刺叶草、黄皮草-刺叶草、黄皮草-丹参草。另一个联盟,长甲军团(=Koelerio-Phleion phleoidisp.)。是向柯氏-柯氏类过渡,其地位有待进一步评价。在研究区域内,我们还建立了所有中生统和长尾-短足纲的关联的正式定义。使用(i)整个目的aTWINSPAN分类,(ii)区域限制数据集的twinspanclassification(通常是一个国家的所有brachypoditalia地块)和(iii)现有的国家分类方案来确定关联。所有的正式定义都是用JUICE程序的专家系统语言编写的。对植物区系的相似性和梯度有更全面的了解。我们对这些协会进行了DCA协调。我们的研究结果表明,东欧森林草原带的草甸草原与中欧的半干旱草原非常相似。

Formalized classification of semi-dry grasslands in central and eastern Europe
European semi-dry grasslands are among the most species-rich vegetation types in the northern hemisphere and form an important part of the habitat mosaics in the forest-steppe zone. However. there is no comprehensive evaluation of the variation in their composition and the phytosocio-logical classification of these grasslands. For the syntaxonomic revision, we used a dataset of 34,173 vegetation plot records (releves) from central and eastern Europe. which were assigned to the class Fesiuco-Bromeiea using the diagnostic species listed in the EuroVegChecklist. To determine the diagnostic species of the orders, we used a TWINSPAN classification of the whole dataset. Of the total dataset, 15,449 releves were assigned to the order Brachypodietalia pinnati. which corresponds to semi-dry grasslands. This subset was again classified using TWINSPAN. Formal definitions of the following alliances were established: Mesobromion erecti, Cirsio-Brachypodion pinnati (incl. Fragario-Trifolion montani. Agrosiio-Avenulion schellianae, Scabioso ochroleucae-Poion angustifoliae and Adonido vernalis-Stipion iirsae), Scorzonerion villosae and Chrysopogono-Danshonion. Another alliance, Armerion elongatae (=Koelerio-Phleion phleoidis p.p.). is transitional towards the class Koelerio-Corynephoreiea and its status needs further evaluation. We also established formal definitions of all of the associations of Mesobromion and Cirsio-Brachypodion within the area studied. Associations were identified using (i) a TWINSPAN classification of the whole order, (ii) TWINSPAN classifications of regionally restricted data sets (usually all Brachypodietalia plots in one country) and (iii) existing national classification schemes. All formal definitions were written in the expert system language of the JUICE program. To obtain a more complete picture of the floristic similarities and gradients. we performed a DCA ordination of the associations. Our results revealed that meadow steppes in the forest-steppe zone in eastern Europe are very similar to semi-dry grasslands in central Europe.

期刊介绍: Preslia is a peer-reviewed scientific journal publishing original research papers on plant systematics, morphology, phytogeography, ecology and vegetation science, with a geographical focus on central Europe. The journal was founded in 1914 and named in honour of brothers Jan Svatopluk Presl (1791–1849) and Karel Bořivoj Presl (1794–1852), outstanding Bohemian botanists. It is published quarterly by the Czech Botanical Society.
