MAPPING OF THE SOIL-PLANT COVER IN YAKUTSK BOTANICAL GARDEN

Large-scale inventory maps of soil and vegetation cover are important for protected areas, especially in the context of increasing technogenic pressure. The purpose of our research was to map the soil and vegetation cover in Yakutsk Botanical Garden on a landscape basis using GIS technologies to ensure environmental management and monitoring of the ecological status. Today, the use of GIS technologies makes it possible to implement integrated mapping of biodiversity through the creation of a large-scale coordinated series of landscape and thematic maps of soil and vegetation cover. The use of GIS technology allowed us to produce maps describing basic natural conditions of the landscape-typological structure of the soil and the vegetation in the scale 1:10 0 00. The methodology for the creation of cartographic models was based on the analysis of the composition and structure of soil-plant complexes within the boundaries of landscape contours, pre-selected topographic map scale 1:2 000. The basic landscape map allows displaying more general patterns at the level of groups of types of tracts. The establishment of a landscape base at this level allows for the generation of various thematic maps, both for the assessment of land cover structure and for the assessment of the environmental situation in general. The compilation of a soil map on a landscape basis involves the development of a parallel comparative scheme of typological landscape units and typological units of the structure of the soil cover. Cartographic models of vegetation cover, created on the principle of mapping the distribution of vegetation complexes, which refers to the combination of phytocenoses and groups of plants, coexisting in the boundaries of landscape contours of a certain dimension. On the basis of practical application of GIS-technologies regularities in spatial distribution of landscapes, soils and vegetation were revealed. The developed maps of soil and vegetation cover allow analyzing and evaluating of the environmental value and biogeographic specificity of the territory of Yakutsk Botanical Garden, to determine the priority and effectiveness of the protection of individual species and ecosystems, to plan environmental activities
