  1. Ch8. Models of urban structure and the internal structure of cities- case study • 1. Location • 2. Urban process- the evolution of urban patterns ~ it includes 7 stages • 3. Urban population distribution • 4. Dynamic forces in city development ~ Centrifugal forces (push factors) ~ Centripetal forces (pull factors)

  2. Internal Structure of a city – Sydney • 1. General description • 2. Central Business Districts ~ Introduction ~ characteristic of a CBD ~ Vertical variations in rents and uses ~ Small residential population ~ Traffic congestion ~ few manufacturing industries ~ Dynamic and changing nature

  3. 3. Specialized areas in the CBD • 1. Service-finance-office zone • 2. The administrative area • 3. The retailing area • 4. Warehousing and manufacturing • 5. The entertainment area • 6. Residential area • 7. Open spaces

  4. The zones in transition • Basic characteristics ~ this is an urban zone which commonly adjoins the CBD and is undergoing change, changing from a residential function to functions associated with the CBD ~ sectors in the transitional zone ~ Delimiting the zone in Transition

  5. The residential areas • Inner residential areas • Suburban residential areas • Reasons for the development of the urban fringe • Characteristics of suburban low density housing

  6. Manufacturing zone ~ older industrial areas ~ newer industrial districts Shopping centres ~ a hierarchy of retail business districts ~ the selection of a retail site

  7. Hypermarkets (regional shopping centres) • Characteristics ~ carefully planned ~ out of town ~ provide a wide range of goods and services ~ a single complex serving a population of 250000 or more ~ Large car parks ~ serves only mobile and affluent population who are able to drive and can afford bulk purchases

  8. Other urban functions • The other urban function,which complete the land use pattern of Sydney are : ~ The port zone has been developed around Botany Bay, whilst parts of the old port near the CBD have been abandoned ~ Transport routes ~ Military land use ~ Recreational reserves

  9. Hong Kong • 1. Location,spacing and size ~ locational advantages ~ Sizes and spacing of settlements 2. Functions ~ Communication functions ~ Economic functions ~ Other functions

  10. 3. Urban population densities • High population density • Variations in population densities

  11. 4. Urban land rents • The CBD • Away from CBD • Local peaks of high land values • Industrial districts • Public housing estates and squatter areas

  12. 5. Urban land use zones in Hong Kong • 1. Characteristics • 2. Central Business District (CBD) • 3. Retailing zones • 4. Manufacturing zone • 5. Residential areas • 6. zones in transition • 7. Rural-urban fringe/ suburbs

  13. 6. Models of urban structure • ~ burgess’s concentric model • ~ hoyt’s sector model • Application of Burgess,and Hoyt’s model to Hong Kong • Harris and Ullman’s multiple nuclei model
