Aims: To create a comprehensive, consistent and unequivocal phytosociological classification of European marsh vegetation of the class Phragmito-Magnocaricetea. Location: Europe. Methods: We applied the Cocktail method to a European data set of 249,800 vegetation plots. We identified the main purposes and attributes on which to base the classification, defined assignment rules for vegetation plots, and prepared formal definitions for all the associations, alliances and orders of the class Phragmito-Magnocaricetea using formal logic. Each formula consists of the combination of “functional species groups”, cover values of individual species, and in the case of high-rank syntaxa also of “discriminating species groups” created using the Group Improvement (GRIMP) method. Results: The European Phragmito-Magnocaricetea vegetation was classified into 92 associations grouped in 11 alliances and six orders. New syntaxa (previously invalidly published according to the International Code of Phytosociological Nomenclature) were introduced: Bolboschoeno maritimi-Schoenoplection tabernaemontani, Glycerio maximae-Sietum latifolii, Glycerio notatae-Veronicetum beccabungae, Schoenoplectetum corymbosi and Thelypterido palustris-Caricetum elongatae. Based on a critical revision, some other syntaxa were rejected or excluded from the class Phragmito-Magnocaricetea. Conclusions: This work provides the first consistent classification of the class Phragmito-Magnocaricetea at the European scale, which is an important tool for nature conservation. Our classification largely respects previously existing concepts of syntaxa, but it also proposes modifications to the recently published EuroVegChecklist. This work also provides a protocol that can be used for extending the current classification to new syntaxa and geographical regions.

欧洲沼泽植被（Phragmito-Magnocaricetea）到协会级别的分类

目标：创建一个全面的、一致的和明确的欧洲沼泽植被的植物社会学分类。地点：欧洲。方法：我们将鸡尾酒法应用于欧洲 249,800 个植被地块的数据集。我们确定了分类的主要目的和属性，定义了植被图的分配规则，并使用形式逻辑为 Phragmito-Magnocaricetea 类的所有关联、联盟和订单准备了正式定义。每个公式都由“功能物种组”、单个物种的覆盖值以及在高级句法的情况下使用组改进 (GRIMP) 方法创建的“区分物种组”的组合组成。结果：欧洲 Phragmito-Magnocaicetea 植被被分为 92 个协会，分为 11 个联盟和 6 个目。引入了新的语法（根据《国际植物社会学命名法典》先前已失效）：Bolboschoeno maritimi-Schoenoplection tabernaemontani、Glycerio maximae-Sietum latifolii、Glycerio notatae-Veronicetum beccabungae、Schoenoplectetum corymbosi 和 The。根据批判性修订，一些其他句法被拒绝或排除在 Phragmito-Magnocaricetea 类之外。结论：这项工作首次在欧洲范围内对 Phragmito-Magnocaicetea 进行了一致的分类，这是自然保护的重要工具。我们的分类很大程度上尊重先前存在的句法概念，但它也建议修改最近发布的 EuroVegChecklist。这项工作还提供了一个协议，可用于将当前分类扩展到新的语法和地理区域。
