摘要

分析了卢甘斯克地区“Honcharivskyi”植物保护区(Svatove区)的植物区系现状。保护区包括科比尔卡河和克拉斯纳河右岸斜坡上的三个区域,露出白垩基岩。这项研究是在2019年夏季和秋季进行的。组织了四次远征旅行,前往奥博罗特尼夫卡村和瑙霍尔内村附近的地区。用样线法进行的植物区系描述保存为研究资料。植物区系组成通过样带植物物种清查进行鉴定。结果编制了维管植物2科3纲29科74属85种的带注释名录。在系统组成上,主要科以菊科(22种,占总区系的25.9%)、禾科(9种,10.6%)和Lamiaceae(7种,占总区系的8.2%)为主。这些科包括相当数量的原始、草原和钙质物种。以草原草甸草本植物为代表的半隐植物在植物区系生物形态结构中占优势(51种,占60%)。变色虫(在我们的案例中研究的是亚灌木,生长在草原斜坡上,白垩和石灰石露头,即,金尼斯塔·丁托利亚·L.,白垩纪·杜比扬。(Teucrium polium L.)最少(6种,7.1%)。形态分析显示,野生种占优势(35;41.2%),主要原因是放牧、践踏和经济活动。植物区系生态分析基于反映气候和土壤性质的5个主要因子。在土壤酸度方面,嗜中性物种占主导地位(53种,63%);在碳酸盐化合物方面,嗜碳物种占主导地位(34种,40%);在土壤盐度方面,富营养化物种占主导地位(36种,43%);在气候热状态方面,亚中热状态(59种,70%);在气候大陆性方面,半大陆性物种占主导地位(43种,52%)。大多数记录的物种喜欢微酸性和/或中性,富含盐和碳酸盐,草甸样和普通黑钙土的草原草甸和草原。有保护价值的有7科11属12种。其中10种被列入乌克兰红色数据手册,5种被列入欧洲维管植物红色名录(Hyssopus cretaceous Dubjan)。黄花蒿;前贝瑟,半人马座多涅茨卡Klok。;;;;;, Hedysarum白垩纪Fisch.), 2种被列入卢甘斯克地区植物红色名录(thyymus calcareus Klokov & Des.-Shost.)。和直立蕨(L.)Raeusch)。

The flora of the botanical preserve “Honcharivskyi” (Luhansk Region, Ukraine)
The current state of the flora of the botanical preserve “Honcharivskyi” (Svatove District, Luhansk Region) is analysed. The preserve includes three areas on the right-bank slopes of the Kobylka and the Krasna rivers with outcrops of chalk bedrocks. The study was conducted in summer and autumn 2019. Four expeditionary trips were organized to the areas near the villages of Oborotnivka and Nauholne. Floristic descriptions made by the line-transect method saved as research material. Identification of floristic composition was carried out by the plant species inventory along the transects. As a result, an annotated list of 85 species of vascular plants of 74 genera, 29 families, 3 classes and 2 divisions was compiled. In terms of systematic composition, the spectrum of main families is headed by Asteraceae (22 species, 25.9 % of the flora), Poaceae (9 species, 10.6 %), and Lamiaceae 7 (species, 8.2 %). These families include a significant number of ruderal, steppe and calcephilous species. Hemicryptophytes, represented by herbaceous plants of steppe meadows, prevail in the flora biomorphic structure (51 species, 60 %). Chamaephytes (in our case study the subshrubs, growing on steppe slopes, chalk and limestone outcrops, viz., Genista tinctoria L., Hyssopus cretaceus Dubjan., Teucrium polium L. etc.) are least presented (6 species, 7.1 %). A cenomorph analysis revealed predominance of the ruderal species (35; 41.2 %) due to grazing, trampling and economic activity in the study area. The flora ecological analysis was based on five main factors, which reflect climate and soil properties. In terms of soil acidity, the neutrophilic species formed a dominating group (53 species, 63 %), in terms of carbonate compounds – the acarbonatophilic (34 species, 40 %), in terms of soil salinity – the eutrophytic (36 species, 43 %), in terms of climate thermal regime – the sub-mesothermic (59 species, 70 %), and in terms of climate continentality – the hemicontinental ones (43 species, 52 %). Most recorded species prefer slightly acidic and/or neutral, rich in salts and carbonates, meadow like and common chernozems of steppe meadows and steppes. Twelve species of 11 genera and 7 families are of conservation concern. Of these, 10 species are listed in Red Data Book of Ukraine, five species are in the European Red List of Vascular Plants (Hyssopus cretaceus Dubjan., Artemisia hololeuca M. Bieb. ex Besser, Centaurea donetzica Klok., Cephalaria litvinivii Bobr., Hedysarum cretaceum Fisch.), and two species are in the Red List of plants of Lugansk Region (Thymus calcareus Klokov & Des.-Shost. and Potentilla erecta (L.)
