Аssessment of stability of ecosystems

Abstract

The transformation of ecosystem behavior with the change of unstable equilibrium persistent imbalances in the light of nonlinear dynamics. The task of ensuring the sustainability of ecosystems inseparable from the search admissible class of perturbations that it can withstand and not lose with the stability of their condition or movement. Focusing the analysis on the nature of the perturbations corresponds to the classical theory approach, because the essence of the stability concept is in calculation of numerical values of the perturbations for the given deviation estimates rather than in nature of the change of the perturbed movement versus undisturbed. The paper proposes expansion of methodological means of investigation and stability sustaining of the ecosystems through involvement of traditional system approaches. The analysis of ecosystem diversity, accompanied by justification of ordering options that allows us to formulate the principle of sufficiency in ecosystems, enter the parameters of heterogeneity and irregularity of states to classify these ecosystems.
