Modeling the Spatiotemporal Variability of Geosystems

The main features of classical structural-dynamic models (V.B. Sochava’s epifacie model and A.A. Krauklis’s system of dynamic factor series) are considered, which reflect equifinal and variable states of geosystems, their transformation trends, and the dynamic relationships that have developed between geosystems in the landscape. A scheme of landscape development is described, on the basis of which various categories of “dynamic processes” are analyzed, affecting the increase and decrease in the degree of spatial and temporal changeability of geosystems, as well as showing the mechanism for achieving the native (equifinal) state by serial geosystems. Based on this analysis, it is proposed to identify a new dynamic state of geosystems: a transitional (intermediate) one located between serial and equifinal states in the dynamic factor series of geosystems. Two categories of epigeomer models are shown: (1) epifacie (epigeomer) of the landscape and (2) epigeomer. The former model describes the macrogeochore as a structurally dynamic and spatially functional whole, and the latter model characterizes the epigeomers of various hierarchical levels and reflects not only the structural-dynamic relationships between geomers, but also their typological and classification–hierarchical (taxonomic) subordination. Using the example of geosystems of southern Cis-Baikal, a generalized hierarchical model of epigeomers of the topological level belonging to the mountain-taiga dark coniferous geome of conditions of limited development is constructed. This model shows an invariant–variant multilevel structure that reflects the spatial and temporal changeability of geosystems at different levels of the hierarchy and emphasizes their subordination and features of manifestation at each level.
