Ecological niches of major soil types in Russia: Geographical aspects of the new Russian soil classification system

The soil cover of the territory of Baikal region is characterized by a significant variety, and the structure of soil cover – by a high complexity due to complex geological history of the region, to the influence of tectonic processes of the Baikal rift zone, to the wide spread of young mountain systems, island permafrost and other factors. Distribution of loess rocks at the territory of the forest-steppe zone of Baikal region contributes to the genesis of fertile soils, but increases the heterogeneity of soil cover, which should be considered in agricultural land use.

A comprehensive study of ecological functioning features of the soils, formed on outputs of phosphorites’ layers of Ongolignur deposit of Khovsgol phosphorite basin of South-Western branch of Baikal rift zone was conducted. The understanding of the soil-ecological potential of the soil cover of the studied area both in the conditions of natural development of geosystems and under the influence of destabilizing anthropogenic factor was expanded. The possible consequences of the technogenic pressure to the unique natural ecosystem of lake Khovsgol have been studied in aspect of potential mining of the phosphorite deposit. Within the study, it was found that the soil formation, soil chemistry and biogeochemical migration of phosphorus and other elements, the humus state of soils and biological productivity of biocenosises (that is the natural-resource potential) of the study area is strongly determined by the influence of lithogenic basis (matrix) of soil, intrazonal factors and cryogenesis.

Sustainable development of the Baikal-Khuvsgul basin is not only of national, but also of great international importance. This status gives priority to preserving biodiversity and the natural-historical biosphere in general, and to the development of strategies for the rational utilization of natural resources and sustainable development of territories within the basin of the unique ecosystems of Lakes Baikal (Russia) and Khuvsgul (Mongolia). We carried out a comprehensive study of the morphogenetic and ecological features, ecological stability of soils and landscapes of the Khuvsgul phosphorite basin of the mountainous Khuvsgul region of the southwestern branch of the Baikal rift zone (BRZ). This analysis upgraded the existing knowledge of possible trends in the transformational growth and ecological balance of the soil cover of this territory both under the conditions of the natural development of geosystems and under the destabilizing anthropogenic and technogenic impact. Possible negative side effects of the development of phosphorite deposits on the unique in natural and cultural terms ecosystems of Lake Khuvsgul were predicted.
