The scheme of soil-geographical zonation of Lviv oblast is developed on the principles of structural approach to the spatial organization of soil cover. Criteria for allocation of the ranked taxonomic units, their spatial and genetic properties are qualitative and genetic indicators of soil cover with the analysis of the spatial arrangement of soil combinations and structures.The following taxonomic units are identified in the proposed scheme of soil-geographical zonation: soil-geographic kraina (soil-geographic country), soil-bioclimatic zona/poias (soil-geographic zone/mountain belt), krai (region), okrug (county or mountainous soil region), rayon (district), masyv (massif).A mandatory criterion for all taxonomic units of soil-geographical zonation is the type of soil cover mesostructures (spatial-geometric characteristics of elemental soil areals and their spatial structures, as well as the dominated class of soil combinations).Two soil-geographic kraina (countries) are identified within Lviv oblast: the East European Plain and the Carpathians; three soil-bioclimatic zones: moraine-sander (popilnyakova) zone of mixed forests, broadleaf forest, forest-steppe (loess) and mountain-brownsoil zone; six soil krai: Malopoliskyi, Volynskyi, Roztots’ko-Opilskyi, Zahidnopodilskyi, Peredkarpatskyi highland, the Carpathian mountain; 13 soil counties and 4 regions.Key words: zonation, soil cover structure, zone, krai, okrug, Lviv oblast.
