Multiple Nuclei Model


The multiple nuclei model was proposed in 1945 by C. Harris and E. Ullman. The model shows thahttp://www.blogger.com/img/gl.photo.gift cities may grow from not on CBD, but from several independent growth poles (nuclei).

The model shows that some urban functions exist in pockets because of the advantages of a particular site.

Hoyt's Sector Model


Hoyt developed the Burgess model, suggesting that urban settlements' land uses are modified by their relative accessibility to transport routes.He expanded on Burgess' five zones, adding another three, including outlying business districts and dormitory suburbs.

The Hoyt model was developed in 1939 by economist Homer Hoyt.

Burgess Concentric Zone Model


The Burgess Concentric Zone Model was created in the 1920s by American geographer E.W. Burgess.

Burgess divided cities into 5 key zones, with the CBD in the centre. he suggested that a city would develop its land use in all directions around the CBD.

Auckland can be modeled by the Burgess model.
