Abstract: | Some basic concepts and principles of general systems theory applicable to geographical systems are formulated. A geosystem is viewed from the point of view of the controllable processes that convert it from one state to another and insure its self-regulation and stability. Since geographical systems derive energy from the surrounding environment and use it for their physical-chemical and biological functions, the structural elements of such systems behave thermodynamically like automata performing irreversible processes, and the laws of thermodynamics can therefore be applied to the functioning of such systems. A mathematical apparatus is demonstrated for the study migratory flows of mass and energy in geographical systems. |
