Sustainability of forest ecosystems, methods of its calculation and mapping

A brief review of the state of the problem of stability in forest ecology is presented, and the known mathematical models of ecosystem sustainability are estimated in the context of their applicability to landscape-ecological systems. The ideology of quantitative evaluations of forest ecosystem potential sustainability is described. Two levels of sustainability are distinguished - labile phytocoenological and passive soil-biotical. Statistically significant relations in equations have been obtained that describe the dependence of these indices on metabolic features of forest biogeocoenoses and on environmental factors. The presented large-scale and small-scale matrix maps of resistance and resilience stability of forest facies (by the example of Samarskaya Luka) and forest formations (for the Oka-Volga basin) characterize their sensitivity to climatic changes and subsequent succession/restoration potential, respectively.
