摘要

本文描述了Synyukha河谷草原部分(乌克兰南部的南部Bug集水区)的植被多样性模式,该地区由20个联盟、14个目和13个类组成。研究发现,植被的总体分化受土壤因素(土壤湿度、氮含量和通气量)的影响最大,而受阻尼变异性、盐度和酸度的影响较小。缬草、小檗、刺李和紫苏的植被生态因子与锡牛哈河流域草原部分的背景生态指标最为一致。花岗岩露头具有较高的cenotic多样性和特定的植被。根据计算,我们证明了Syniukha河流域的草原部分是Carpinion betuli森林分布的南部极限,因为条件接近其生态最佳极限。

Synphytoindication assessment of the steppe part of vegetation of the Syniukha River valley (the Southern Bug catchment area, Ukraine)
The article describes vegetation diversity patterns of the steppe part of the Synyukha River valley (the Southern Bug catchment area, southern Ukraine), which is represented by 20 alliances, 14 orders, and 13 classes. It has been found that general differentiation of the vegetation is most influenced by edaphic factors (soil moisture, nitrogen content, and aeration), and somewhat less – by damping variability, salinity and acidity regime. The vegetation ecofactors of the alliances Festucion valesiacae, Berberidion vulgaris, Prunion spinosae, and Prunion fruticosae best correspond to the background ecological indicators of the steppe part of the Syniukha River basin. The high cenotic diversity and specific vegetation of the granite outcrops were observed. Based on the calculations, we demonstrated that the steppe part of the Syniukha River catchment area is the southern limit of distribution of Carpinion betuli forests due to the conditions close to the limits of their ecological optimum.
