Аннотация: Abstract—The methods for developing the theory of geosystems are analyzed. The postulates necessary forphysical and mathematical modeling of the structure and functioning of geosystems are formulated. The differentiationof landscapes is formalized on a grid of digital elevation models using statistical methods basedon morphometric parameters describing the redistribution of geophysical fields (gravity and insolation) anddigital values of the brightness of remote sensing channels and NDVI index values. The reality and rank ofboundaries are verified using spatially continuous geophysical methods. Field digital methods of ground penetratingradar and electrical resistivity tomography complement each other: they are based on measuring variousphysical properties of sediments and differ in depth and resolution. The methods demonstrated the reliableidentification of lithology, significantly complementing drilling data. Modeling of the functioning processesof geosystems in terms and expressions of continuum mechanics is closely related to the structure oflandscapes through boundary conditions and distributed geophysical parameters of transport processes. Themultiplicity of approaches to describing the structure and functioning of geosystems (methods of thermodynamics,continuum mechanics, multivariate statistics, synergetic approach, fractal geometry, landscape “patterns”using statistical distributions, stochastic differential equations of the theory of Brownian motion, etc.) isdue to the real complexity natural processes. Based on the parameters of physical models of the transfer ofradiation, heat, moisture and nutrients in the environment and within plants and models of photosynthesis,respiration, and the redistribution of assimilates, the most important biogeophysical processes of transformationof matter and energy for the self-development of landscapes are considered, including production processesin the vegetation cover and processes of decomposition of organic matter. The description of the landscapeas a dynamic system makes it possible to formulate and solve the problem of the optimally managingnatural resources.Keywords: geosystems theory, geophysical paradigm, modeling, landscape structure and functioning
