Abstract

The primary successions of vegetation have been investigated in the continental conditions of the Severo-Chuiskiy center of present-day glaciation (Central Altai) from the colonization of deglaciated terrains by the first plants to the formation of simple plant groups to the primary plant communities. The observations were carried out for 15 years on the young moraines of the valley glaciers of Malyi Aktru (2200–2250 m a.s.l.) and Bolshoi–Levyi Aktru (2370–2500 m a.s.l.) in chrono-sequences from the ends of glaciers to the moraines of the mid-19th century. Three stages and four sub-stages of the primary succession of vegetation are identified. The species composition of vascular plants, mosses, and ground lichens is identified; the dominant species and the peculiarities of primary vegetation are characterized. Ideas about the course of successions and their peculiarities at different altitudes in the upper part of the forest and subchalet altitudinal zones are obtained. It has been found that, in the 150 year period, a young forest community has been formed on new moraines in the upper part of the forest altitudinal zone, and a combination of microcenoses similar to tundra communities have been formed in the alpine altitudinal zone. The primary succession of vegetation on both glacier forelands has some similarities, especially in early stages of ecosystem development (pioneer species composition and three-stage structure of successions). Strong differences appear during the late stages of succession. The primary succession of vegetation on the foreland of the Malyi Aktru glacier involves 146 species of vascular plants, 44 species of mosses, and 6 species of lichens. On the foreland of Bolshoi Levyi Aktru, 128 species of vascular plants, 26 species of mosses, and 8 ground lichens have been recorded.

Severo-Chuiskiy冰川中心（阿尔泰中部）的年轻芒rain植被的主要演替

摘要

在现今冰川形成的Severo-Chuiskiy中心（阿尔泰中部）的大陆条件下，研究了植被的主要演替过程，从最初的植物在冰川化地区的殖民化到简单植物群的形成到主要植物群落。在从冰川末端到莫兰的时间序列上，对马来阿克特（2200–2250 m asl）和莫斯科大剧院–列维依阿克特（2370–2500 m asl）的年轻冰川葡萄进行了15年的观测。 19世纪中叶。确定了植被原始演替的三个阶段和四个子阶段。确定了维管植物，苔藓和地衣的物种组成；主要植被的特征和特点。在森林和亚小木屋海拔区域的上部，获得了有关演替过程及其在不同高度的特殊性的想法。已经发现，在150年的时间里，在森林海拔区域的上部新的芒rain上形成了一个年轻的森林群落，并且在高山海拔区域形成了与苔原群落相似的微人口组合。两个冰川前陆的原始植被演替都有一些相似之处，尤其是在生态系统发展的早期阶段（先驱物种组成和演替的三阶段结构）。在继承的后期阶段会出现强烈的差异。Malyi Aktru冰川前陆上的植被主要演替涉及146种维管植物，44种苔藓，和6种地衣。在Bolshoi Levyi Aktru的前陆，已记录到128种维管植物，26种苔藓和8种地衣。
