Some aspects of the differentiation of Gobi desert ecosystems caused by climate (sectoral position of the territory on Eurasian continent, latitudinal-longitudinal changes) are reviewed. Diversity of dominant species of plant communities is noted in different regions. Ratios between areas of the different soil-lithological groups of ecosystems are presented. Main factors of anthropogenic transformation of ecosystems have been revealed and main criteria for the assessment of modern conditions of the main ecosystem components (soils and vegetation) have been developed. Ratios between ecosystems subject to different degrees of anthropogenic transformation have been calculated on the basis of ecosystem maps at a 5° scale of transformation. It is shown that anthropogenic transformation of semideserts is greater than that of deserts. Recommendations have been proposed for conservation of the ecosystems of the Gobi desert.
