Ecological Systems and Devices Annotation << Back ENERGETICAL CRITERION FOR FORCASTING ECOLOGICAL DISASTERS R.A. Sedneva, M.A. Mirkin, A.I. Potapov This present work consideres the factors, defining the scale effect of ecology. It is shown, that the most general are the equations of thermodynamics, used in Ecology, which can be used at the decision of applied problems. Considering the general principlesr, it is possible to extract the reversible and irreversible components in physical processes of ecological, that permits to predict the beginning of the ecological disasters. Key words: criterion; prognosis; forecasting; disasters; catastrophies; ecology; the scale factor. E-mail: rsed101@yahoo.com
