What is a Zone System?

The regional system is composed of a set of basic regional units. This regional unit appears in the form of small spatial micro-elements, such as land units, farmland, rural settlements, urban residential areas, and industrial areas. It is reflected in content. A series of geographical elements such as resource conditions, infrastructure and basic production activities are formed. These elements form different combinations in different levels of regional units. It is the integration and interaction of such basic units that constitute regional systems.
