This paper considers the use of the comparative-geographical method in investigating soil-biotic communities from the Tunka depression, for the purposes of cartographic modeling of the spatio-temporal state of taxonomic diversity of soil zoocenoses. To assess the current state of the soil biota, it is proposed to use the Margalef index which implies the value of the number of taxa with a total abundance in soil invertebrate communities. The limits of these changes make it possible to single out a uniform scale with five categories of diversity. The functional and trophic structure of soil zoocenoses with the identification of dominant species of pedobionts permits determination of the optimal composition of the indigenous population of biocenoses as well as understanding the mechanisms of recovery with a decrease in anthropogenic impacts. The generalized data obtained should be represented on a cartographic model. To do this, it is proposed to use a landscape basis which, in turn, reflects both the terrain features and the totality of the set of natural factors: from hydrothermal conditions to the phyto-edaphic appearance of the study area. In general, the results of the study can be used for timely decisions aimed at preserving biological diversity of the region, which, in turn, is one of the main principles of world ecology. An attempt is made to combine and analyze theoretical and methodological knowledge of soil zoogeography and its practical application with the possibility of further development of a so-called symbiosis with related branches of geography, biology and cartography. The results of the research can be used in planning measures for optimal nature management with access to the next level, i. e. the predictive level, which permits management of the processes occurring within the ecosystem of the region.
