Forest growth and minimal model of forest ecosystem organic matter turnover: implication for sustainable forest management analysis. Forest growing stock change in time was derived from minimal model of organic matter turnover in forest ecosystem. Growth curve was calibrated on the base of growth and yield tables data and describe it with high precision as it measured by determination coefficient. Growth and organic matter turnover parameters relationships was established and interpreted. Increment and acceleration curves for growing stock changes were in special manner analyzed and 4 specific tree stands growth stages was formulated as they determined by acceleration curve singular points. Determined growth stages was interpreted and discussed from forest management point of view. Multi-criteria optimization of growing stock use in time was done on the base of special management problem decision and analyzed from point of view of sustainable forest management: carbon cycling, carbon uptake and storage, forest biodiversity conservation, soil and water protection as well as risk of natural and man-made hazards damage. Optimal parameter for continuous cover forestry approach to tree stands use such as proportion between harvested and remaining for further growth growing stock, number of thinning per rotation period and its intensity, time needed for growing stock recovering after harvesting as well as suitability of continuous cover forestry approach for tree stands of different productivity and rate of growth was determined and discussed. Sustainability and resistance of forest growth as well as organic matter turnover in forest ecosystem was examined by catastrophe theory approach and the edge values of external effects were determined in connection with tree stands productivity and growth rate.
