Abstract

The dominance of xeropetrophytic plant communities with original species composition along with high phytocenotic diversity is the first to determine the distinctness of the South Ural low-mountain steppe province within the Ural Mountains. As the zonal steppe ecosystems are totally destroyed and transformed, petrophytic cenoses represent the predominant type of natural vegetation. They are of high conservation importance due to preserving unique biodiversity with a large number of rare and endangered species, relics and endemics (Ryabinina, 2003; Yamalov et al., 2019). Stony steppes in the Southern Urals have been studied for more than 100 years. Initiated in the 1980s, the syntaxonomical research covers now only the limited territories, mainly within the protected areas (Unikalnye ..., 2014; Prirodnye ..., 2018). The recent studies are focused on the relationship between the petrophytic vegetation and macroecological gradients in the context of geographical zonation (Zolotareva et al., 2019; Korolyuk et al., 2020). Our study presents the results of the analysis of 265 relevés of petrophytic communities of the steppe zone, carried out by the authors on the territory of the Gaysky, Kuvandyksky, Saraktashsky and Belyaevsky administrative districts of the Orenburg region, as well as the Khaibullinsky district of the Bashkortostan Republic in 2014–2018 (Fig. 1). Six phytocoenons were identified using the TWINSPAN algorithm followed by manual sorting. They represent the main diversity of petrophytic vegetation in the studied region and differ in the groups of species identified by formal criteria (Korolyuk et al., 2016; Zolotareva et al., 2019). We conducted the cluster analysis to compare these with the petrophytic associations of the Urals: 26 associations from the classes Festuco-Brometea Br.-Bl. et Tx. ex Soó 1947 and Anabasietea cretaceae Golovanov et al. 2021 (Fig. 2, 3). Five communities were assigned to the steppe vegetation, and their position in the syntaxonomical system was determined. Communities 1–3 regarded as typical steppes have similar floristic composition and dominant plants; community 4 is closer to the rich forb-bunchgrass steppes; community 5 and the ass. Anthemido trotzkianae–Thymetum guberlinensis have transitional features to desert steppes. We identified the new alliance Elytrigion pruiniferae all. nov.

Holotypus — the association Elytrigietum pruiniferae Lebedeva ass. nov. Alliance represents xeropetrophytic vegetation of the steppe zone of the South Urals. Its area covers the watersheds of the Sakmara, Ural and Ilek rivers. Its communities were also found on the right bank of the Sakmara river (the Guberlya and Kuragan basins), as well as in the lower part of the Bolshoy Ik river basin.

乌拉尔南部旱生植被的分类学:鞘翅藓属。11月。

具有原始物种组成和高度植物多样性的旱生植物群落优势是乌拉尔山脉内南乌拉尔低山草原省独特性的第一个决定因素。随着地带性草原生态系统的全面破坏和改造，岩生苔藓是天然植被的主要类型。由于保存了大量稀有和濒危物种、遗迹和特有物种的独特生物多样性，它们具有很高的保护重要性(Ryabinina, 2003;Yamalov et al.， 2019)。人们对乌拉尔南部的石质草原进行了100多年的研究。分类学研究始于20世纪80年代，目前仅覆盖有限的领土，主要是在保护区内(尤卡尼耶…, 2014;Prirodnye……, 2018)。最近的研究主要集中在地理区划背景下岩石植被与宏观生态梯度的关系(Zolotareva et al.， 2019;Korolyuk et al.， 2020)。我们的研究展示了作者在2014-2018年在奥伦堡地区的Gaysky、Kuvandyksky、Saraktashsky和Belyaevsky行政区以及巴什科尔托斯坦共和国的Khaibullinsky地区对草原带岩石植物群落的265个相关数据进行分析的结果(图1)。使用TWINSPAN算法识别了6个植物群落，然后进行了人工分类。它们代表了研究区域岩石植物植被的主要多样性，并且根据正式标准确定的物种群有所不同(Korolyuk等人，2016;Zolotareva et al.， 2019)。通过聚类分析，将这些组合与乌拉尔地区的岩生组合进行了比较:Festuco-Brometea Br.-Bl类中有26个组合。et txt . ex Soó 1947和Anabasietea白垩纪Golovanov et al. 2021(图2,3)。将5个群落划分为草原植被，并确定其在分系统中的位置。典型草原群落1 ~ 3具有相似的区系组成和优势植物;4号社区更靠近茂密的束草草原;群落5和牛头草-百里香草具有向荒漠草原过渡的特征。我们确定了新联盟Elytrigion priiniferae all。11月5日:郁金香葱、土耳其花、黄花蒿、半人马草、黄花蒿、乌拉尔阿魏、乌拉尔丽娜、金盏花、金盏花、绣线菊。Holotypus - Elytrigietum pruiniferae Lebedeva ass11 .
