The Study of Spatial Distribution of Permafrost Indicators and Landscape Structure of Central Yamal (the Case of Vaskiny Dachi Geocryological Station)

摘要

In September 2011 members of the scientific expedition of Earth Cryosphere Institute SB RAS conducted a topographic survey of the modeled area in the course of their comprehensive research. The area examined lies within the territory of Vaskiny Dachi geocryological station in the central part of the Yamal Peninsula. Activities conducted at the mo-deled area included a permafrost survey, landscape description and measuring of the moisture content in the seasonally thawed layer the lower part of which was in the frozen state during the survey. The purpose of the presented work is an analysis of the peculiarities of a spatial distribution of permafrost characteristics, depending on landscape structure, position in the relief, vegetative cover and ground composition.
