Main Features of Urban Pedogenesis in Permafrost Areas (Case of Yakutsk City)

摘要

The properties of permafrost soils of Yakutsk and similar soils of neighboring areas are compared (TOC content, pH, electrical conductivity, and carbonate content). The influence of vegetation type, the position in mesorelief, and the elementary urban landscape type upon the distribution of soil properties with depth and their values in root zone are analyzed. It is shown that the relative variability of organic carbon and carbonates in urban soils is affected mostly by the type of elementary urban landscape and the type of ecosystem, whereas the attribution of soils to the form of mesorelief determines the character of change in more labile properties such as pH and electrical conductivity.
