Abstract

The floristic richness of Bosnia and Herzegovina has been extensively studied, however urban flora has only recently garnered attention, but no systematic surveys of urban ecosystems have been carried out. To address this problem, a study of the seven urban floras in Bosnia and Herzegovina was conducted to determine the pattern of floristic diversity and correlation with anthropogenic factors: size of the urban area, ratio of green areas in the total urban area, number of inhabitants, and population density. The first finding of the study is that urban floras in Bosnia and Herzegovina are rich in plant species. The results have shown that the urban floristic diversity largely reflects the natural vegetation of the urban environment, compared to urban floras in other parts of Europe. Species structure reflects the geographical location as well, so are the urban areas in the Mediterranean biogeographical region, Mostar and Blagaj, floristically richer, but at the same time species richness correlates with the total urban area, as in Sarajevo and Banja Luka. Moreover, the proportion of alien species is low and there is no pronounced process of floras homogenisation. Of the anthropogenisation factors, population density correlates most strongly with the richness of urban flora. From the results, we have concluded that urban plant diversity correlates with both environmental and anthropogenic factors, in a way that provides a basis for establishment of conservation programs in urban ecosystems.

波斯尼亚和黑塞哥维那城市植物多样性--自然的反映
摘要 波斯尼亚和黑塞哥维那丰富的花卉资源已得到广泛研究,但城市植物区系直到最近才受到关注,但尚未对城市生态系统进行系统调查。为了解决这个问题,我们对波斯尼亚和黑塞哥维那的七个城市植物区系进行了研究,以确定植物多样性的模式以及与人为因素的相关性:城市面积、绿地在城市总面积中的比例、居民数量和人口密度。研究的第一个发现是,波斯尼亚和黑塞哥维那的城市植物区系拥有丰富的植物物种。研究结果表明,与欧洲其他地区的城市植物相比,城市植物多样性在很大程度上反映了城市环境的自然植被。物种结构也反映了地理位置,因此,地中海生物地理区域的城市地区、莫斯塔尔和布拉加伊的植物物种更为丰富,但同时,物种丰富度与城市总面积相关,如萨拉热窝和巴尼亚卢卡。此外,外来物种的比例较低,没有明显的花卉同质化过程。在人类活动因素中,人口密度与城市植物区系丰富程度的相关性最大。根据研究结果,我们得出结论:城市植物多样性与环境和人为因素都有关联,这为在城市生态系统中制定保护计划提供了依据。

期刊介绍: Urban Ecosystems is an international journal devoted to scientific investigations of urban environments and the relationships between socioeconomic and ecological structures and processes in urban environments. The scope of the journal is broad, including interactions between urban ecosystems and associated suburban and rural environments. Contributions may span a range of specific subject areas as they may apply to urban environments: biodiversity, biogeochemistry, conservation biology, wildlife and fisheries management, ecosystem ecology, ecosystem services, environmental chemistry, hydrology, landscape architecture, meteorology and climate, policy, population biology, social and human ecology, soil science, and urban planning.
