The authors substantiate the strategy of returning the derelict land of man-made landscapes to the biosphere resources. Based on the research into the self-organizing nature of soils and analysis of data of 35-year long monitoring performed at different sites in a variety of climate zones a system of methods and procedures has been developed for the restoration of ecosystem functions of territories. It implies the formation of the biologically active medium by creation of artificial phytocenosis without fertile soil coating for the restoration of derelict land following the concept of natural soil genesis. As compared with natural self-restoration the artificial phytocenosis creates the conditions for higher rates of formation of phytocenosis having the structure of the surrounding natural landscape, implies the growth of ecological capacity and restoration of ecosystem functions of territories. A biogeochemical cycle of elements in the process of derelict land restoration has been simulated based on the concept of natural soil genesis. This model reflects the order of the component biogenic transformation. Based on the data of remote sensing of territories with the use of geoinformation systems the authors have also developed a system of methods and procedures for the prediction of the rate of derelict land restoration and a simulation analytical model for its implementation with due account for abiotic factors. The growth of the organic material content in the biogenic humus accumulation horizon predicted by computational methods is in good agreement with the data of monitoring performed in the process of derelict land restoration based on the concept of natural soil genesis.
