Abstract
Polysystem analysis procedures are revealed in the unity of mathematical, statistical and logical methods of spatial data processing for studying landscape-zonal geospace by using the Volga basin territory as an example. We proceed from L.S. Berg’s conceptual position about the zonal conditionality of the features of the geographical landscape, which is expressed in the ratio of background (zonal) conditions and local (zonal) factors and characteristics of natural components, the interaction of which unites them into a landscape and zonal whole. On the basis of cartographic material, regional features of the influence of the geographic environment on the formation of the areas of groups of landscape species on the territory and in the system of factor spaces and fields with a spatial framework of the organization of landscape geosystems are revealed. The methodology of polysystem analysis is based on the procedures of stratification of holistic formation into many non-intersecting system layers (monosystems), the study of each of which is carried out independently by special methods of specific theories that model earthly reality in special terms. Three layers-types of a theoretical explanation of the connectivity of groups of landscape species have been identified: a functional model of the “attribute-attribute” relationship, a model of object-typological differentiation of the “object-object” territory, and a cluster taxonomic “object-attribute” model. Based on mathematical relationships, the functions of background, frame, landscape-typological and process components of the territorial diversity of the natural environment are determined.
