Zonality And Geographical Zones

A theory of zones is formulated. Zones are regions that form a linearly ordered set in space. Concentric zones can be distinguished around any agent on the basis of the degree of interaction between the agent and its environment. Horizontal and altitudinal natural zones in terrestrial and oceanic areas as well as socioeconomic zones around cities and market centers are geographical zones. The displacement of zones over time is analogous to wave motion. Moving zones are historical periods imprinted upon the landscape. The intersection of two zonal systems forms a mosaic of regions. Artificial zoning is designed to insure an orderly arrangement of parts of a residential neighborhood around a civic and shopping center or around a transportation node.
