Разнообразие засоленных почв котловин Западного Забайкалья ( на примере Иволгинской котловины)

Soil-geographic mapping of Ivolginskaya depression of Western Transbaikalia has revealed a variety of saline soils, which are of postlithogenic trunk of halomorphic, alkaline differentiated and organic-accumulative departments, and sinlithogenic trunk of alluvial department. 43 % of soil cover are effected by salinity, about 16 % of them are characterized by high and very high degree of salinity. Salinity depends on the position in the landscape, the hydrological regime of the territory and litho-chemical properties of parent rocks.
