Ecological Systems and Devices Annotation << Back Methodological Bases for Creating a Fundamental Theory of Biosphere Stability Mileshko L.P Methodological approaches to creating the principles of fundamental theories of biosphere stability: – the nature of the homeostatic mechanism of stability of the biosphere is characterized by self-consistent preservation of balance in material-energy and information interactions in its ecological systems. – the main condition for ensuring the safety of the biosphere is to support its stability by maximizing the information of ecological systems. It is noted that in order to build adequate models of the biosphere, it is necessary to create modern hardware and software complexes (agribusinesses) that can promptly carry out environmental monitoring. Innovative software processing tools play a key role in the agro industrial complex information from environmental systems. Keywords:information, biosphere, biosphere modeling.
