Popis: A system of complex multiparametric description of landscape was developed on micro- and mesohierarchical levels. The field descriptions conducted in Chuya steppe following this system resulted in the database of geological data containing qualitative and quantitative characteristics of the ground ecosystems of Chuya steppe and their basic components (relief, rocks, soils, vegetation). We tested a technique for automatic calculation of specific areal ratio of abiotic and biotic components of a microlandscape using digital photographs of standard plots. We used triangular diagrams to analyze the composition of mesolandscapes. The obtained results can be used for deciphering and interpreting the data of remote sensing of the Earth as well as for map-making and modeling of geosystems on both local and regional levels.
