Abstract

The combination of steppe and tundra locations at Altai highland depressions—Bertek and Khindiktig-Khol’—is considered with regard to verifying the hypothesis of the existence of a tundra steppe in northern Eurasia during the Last Glacial Maximum (LGM) and its contemporary landscape analogues. Data on soil–vegetation cover diversity at the Altai highland depressions are represented. Cause-and-effect relations explaining the spatial differentiation of nature complexes are identified. The thermal regime of locations with the predominance of steppe and dwarf-birch vegetation is investigated. The interrelation between soil–vegetation cover differentiation and distinction in the microclimate and the permafrost boundary are proved.

阿尔泰高地坳陷苔原和草原位置：植被群落和土壤覆盖特征及其热规律

摘要

阿尔泰高地洼地（Bertek 和 Khindiktig-Khol'）的草原和苔原位置的组合被考虑用于验证末次盛冰期 (LGM) 期间欧亚大陆北部苔原草原存在的假设及其当代景观类似物. 代表了阿尔泰高原洼地土壤-植被覆盖多样性的数据。确定了解释自然复合体空间差异的因果关系。调查了以草原和矮桦树植被为主的地区的热状况。证明了土壤-植被覆盖分化与小气候和多年冻土边界区分之间的相互关系。
