The conceptual and terminological similarity and differences in F.I. Kozlovsky's, A.A. Krauklis's and V.N. Solntsev's views of the three components of the structure of system organization of landscape (geosystem): the biotic/biogeochemical, mobile and conservative components, are considered. It is shown that Kozlovsky’s concept of the migration structure of landscape has an intransient significance for an understanding of systemic integrity of landscape as the object for study and mapping. Special attention is concentrated on the landscape-ecological focus of Krauklis'concept.Keywords: geosystem, landscape, components of natural organization of landscape: inert, mobile, and biotic/biogeochemical.
