The conceptual models evolution of biosphere reserves functional zoning

The evolution stages of biosphere reserves (BR) functional zoning dimensional models from ideal to clustered has been reviewed. The classification of world modern biosphere reserves has been realized based on their territorial structure. Two types, four species and seven subspecies of BR dimensional models have been distinguished. Key words: biosphere reserve, the main area (the nature protected core), the buffer zone, the transition area (transit zone), the cluster structure.
