Abstract

The regularities of biomorphological, ecological, and species differentiation of phytocenoses in the most arid southeastern sector of the Altai Republic reflect a tendency towards the local formation of a complete type of arid vertical zoning. This is typical for arid mountains of Central Asia and includes the following belts (from bottom to top): (1) dwarf shrub deserts, (2) communities of thorn cushion plants (mountain xerophytes), (3) high-mountain steppes, and (4) cryophyte cushion plant formations. The relatively wide spread of this zoning type (in areas with sufficient height of the mountains), including belts of thorn cushion plants and cryophyte cushion plant formations, requires the revision of traditional botanical–geographical concepts in order to increase the diversity of higher vegetation syntaxa and orobiomes both in the Southeastern Altai and in the mountains of South Siberia in general.

南西伯利亚山区有山地旱植物吗？

摘要

阿尔泰共和国东南部最干旱地区植物群落的生物形态、生态和物种分化规律反映了当地形成完整干旱垂直区带类型的趋势。这是中亚干旱山区的典型特征，包括以下带（从下到上）：（1）矮灌木荒漠，（2）刺垫植物群落（山地旱生植物），（3）高山草原，以及(4) 冰冻植物垫层植物层。这种分区类型的分布相对广泛（在山脉高度足够的地区），包括荆棘垫状植物带和冰冻植物垫状植物带，需要修改传统的植物地理学概念，以增加高等植被句法的多样性以及阿尔泰东南部和南西伯利亚山区的奥生物群落。
