Cherkashin A.K., Bibaeva A.Yu. FIELD AND REMOTE RESEARCHES AND MATHEMATICAL MODELING OF MOUNTAIN-STEPPE ECOSYSTEMS ON LANDSCAPE BASIS // Arid ecosystems. 2020. V. 26. № 4 (85). P. 108-115. | PDF
The results of research, construction and information support of ecosystem models based on spatial data using landscape GIS technology are discussed. The article considers the features of building models to describe the degradation of mountain-steppe ecosystems in the coastal zone of the lake Khubsugul (Mongolia) under the influence of natural and anthropogenic factors, taking into account the altitude differentiation of different types of ecosystems. Mathematical models are theoretically justified in the form of ordinary differential equations on a parameter and partial derivatives on factors of influence in terms of the reliability of ecosystem functioning.
Key words: mountain-steppe ecosystems, mathematical modeling, landscape-typological mapping, Ciskhubsugul landscapes, land degradation, grazing pressure.
