Approaches for classifying common hazel-dominated communities differ substantially among countries in Europe. Based on differing criteria, authors have classified identical communities within different higher syntaxa or have classified different communities within one unit. In Slovakia, the situation has been similar. These facts motivate us to accomplish (i) complex syntaxonomical revision of common hazel scrub in Slovakia, ii) comparison of West Carpathian communities with relevant Alpine and Hercynian ones, and iii) identification of the main environmental drivers of variation in their floristic composition. Based on the numerical classification of 415 relevés, two main units were distinguished. They were identified with the Pruno spinosae-Coryletum Jurko 1964 and the Lonicero nigrae-Coryletum Jurko 1964 associations. The main predictors of species’ compositional variability were found to be temperature, followed by moisture, light, and soil reaction. After comparison with all relevant communities from Alpine and Hercynian regions, both associations were classified within the alliance Populo tremulae-Corylion avellanae Br.-Bl. ex Jurko 1964 nom. invers. propos., the order Prunetalia spinosae Tx. 1952 and the class Crataego-Prunetea Tx. 1962. Relations with the other hazel-dominated communities and their classification are discussed in detail.

欧洲各国之间对以榛树为主的常见群落进行分类的方法大不相同。基于不同的标准，作者在不同的较高语法中对相同的社区进行了分类，或者在一个单元中对不同的社区进行了分类。在斯洛伐克，情况相似。这些事实促使我们完成（i）在斯洛伐克对普通榛树灌木进行复杂的句法修改，ii）将西喀尔巴阡社区与相关的高山和海西社区进行比较，以及iii）确定其植物组成变化的主要环境驱动因素。根据415个关联的数字分类，区分了两个主要单元。他们被确认与李子棘-Coryletum Jurko 1964和黑忍冬-Coryletum于尔科1964年成立的协会。物种组成变异性的主要预测因子是温度，其次是水分，光照和土壤反应。与来自高山和海西地区的所有相关社区进行比较之后，两个协会都被归入了Populo tremulae-Corylion avellanae Br. -Bl联盟。前尤尔科1964年 反演。propos中，为了Prunetalia酸枣仁的Tx。1952年和Crataego-Prunetea Tx类。1962年。详细讨论了与其他榛树为主的社区的关系及其分类。
