On the basis of the analysis of data of geobotanical, hydrogeochemical and microbiological observation during 2002–2015 years on east part of Vasyugan bog complex (Western Siberia) is offered a hypothesis of formation of a convex relief of oligotrophic bog ecosystems as a result of the adaptation of system “a pine – bushes – sphagnum mosses” to hydrological and hydrogeochemical conditions and mutual influence of biotic and abiotic components. The pine forms “base” of ecosystems, bushes – “a force layer”, and sphagnum mosses act in a dual role “filler” of ecosystem and “stimulator” of a vertical gain of a surface. Oligotrophic bog ecosystem is not equilibrium and continuously changes depending on hydrogeochemical conditions which adjust quantity of accessible biogenic elements (the first – connections of Ca and P), an oxygen regime of a peat deposit, deducing or transformation of toxic products of biogeochemical and biochemical processes (for example, Al and NO2). Concentration of toxic substances in many respects depends on functioning oxidizing and regenerative geochemical barriers, which, in turn, are connected with a water mode of a bog and properties of bog vegetation.
