ABSTRACT

Urban forests are basic elements in the ecological structure of cities. The dendroflora and herb species of oak-hornbeam forests in a medium-sized city type was studied and compared with nature reserves located outside the city, based on phytosociological analysis using the Braun-Blanquet percentage-of-cover scale. More inconsistent trees and shrubs occurred in the urban forests and some tree species showed poor renewal. The herb plant species have become more frequent in nature reserves, but we were not able to detect significant differences regarding species inconsistent with the habitat. Herb plants in urban forests preferred more light and fertile habitats. Myrmecochory was the most common seed dispersal. Nowadays, the conservation of urban biota is of great importance and more sustainable approaches towards management of nature are needed. To implement such approaches, results of studies focused on ecology of urban forests may serve as an important tool.

摘要

城市森林是城市生态结构的基本要素。根据使用Braun-Blanquet覆盖率比例的植物社会学分析，研究了中等城市类型的橡树角树森林的树突植物和草本物种，并将其与城市外的自然保护区进行了比较。城市森林中更多的树木和灌木出现不一致的情况，一些树种的更新能力较差。草本植物物种在自然保护区中的频率越来越高，但是我们无法发现与栖息地不一致的物种之间的显着差异。城市森林中的草本植物更喜欢光明和肥沃的栖息地。防线虫是最常见的种子传播。如今，城市生物区系的保护非常重要，需要更可持续的自然管理方法。
