Internal Structure of City
Urban Land Use Pattern
2
Types of Land Use There are different types of land use such as
Commercial land use Residential land use Industrial land use Institutional land use Transportation land use Recreational land use
6
Functional Segregation
Similar activities tend to aggregate together because of Similar locational requirements and External economies of scale different types activities are separated from each other because Different locational requirements Different rent-paying ability Conflicts amongst them
7
Bid Rent Mechanism Land rent decreases with increasing distance from city centre competition for land and accessibility push up the land value/rent different land use has different rent curve because they have different demand for accessibility and space
8
Commercial land use needs large number of people to support their business Greater market threshold highest demand for accessibility require less space Can afford higher rent
9
Residential land use Accessibility is not important
require more space (especially high class residential area) cannot afford high rent
10
Industrial land use Accessibility is not very important
require large area of space cannot afford high unit rent There is great difference between light and heavy industry
11
Bid Rent Curve commercial industrial residential Rent ($/m2)
City centre Distance (km)
12
Bid Rent Curve commercial industrial residential Rent ($/m2)
City centre Distance (km) residential
13
Demand for Space High order retailing business locates nearer to _______________ comparing with wholesaling business because it can afford higher rent and occupies ____________ space. High class residential area locates ____________________ city centre so as to get more space. Heavy industries locate in suburban because ____________________ is needed.
14
Concentric Model C.B.D. Transition Zone Low class residential
Commuter’s zone Transition Zone Middle class residential Low class residential
16
Industrial area can be found along the __________and __________because
river railway
17
Low class residential areas are located next to ___________and ___________________ because
C.B.D. industrial area
18
sea shore the Governor’s house High class residential area can also be found next to _________ and _______________________ because It is also be located away from __________________ because industrial area
19
Mutual Relationship between Different Types of Land Use
Some land uses are mutually exclusive Some land uses are mutually support This will lead to segregation and aggregation of land uses
20
Impact of transport network
Industrial area Middle class residential area Low class residential area High class residential area
21
Multiple Nuclei Model
22
Harris & Ullman Multiple nuclei Model Burgess Concentric Model Hoyt Sectoral Model
24
Other Factors Government planning Physical factors e.g. Relief
New town planning Land use zoning Urban renewal Physical factors e.g. Relief Historical factors Behavioural factors
26
Central Business District(C. B. D
Central Business District(C.B.D.) is located at __________ of the city. Since the C.B.D. is near to the docks and harbour, it is believed that the early function of the city was ____. The rise of regional centres because heart port
27
At some junction of arterial / major transport routes
Relatively high accessibility Especially accessible to the local population Reach the market threshold of some middle order goods / services
28
Hierarchy of Business Centre
C.B.D. Regional business centres Community business centres
29
Rent Distance Rent Distance regional function community function
30
If the level of accessibility of the street junction deteriorates as a result of urban blight, how would the bid-rent curves and land use pattern be affected? Rent Distance
31
Main road Higher accessibility Side street
32
Example Regional centre Community Centre Mong Kok, Causeway Bay
Neighbourhood Centre Mong Kok, Causeway Bay Shun Lee Shopping centre Shun On Shopping centre
33
specialized functional commercial areas
External economies of scale / Agglomeration benefits Reputation Similar requirements Ancillary services e.g. Golden Shopping Centre
34
highway-oriented shopping ribbons
35

Vertical Zonation Zone B Zone C Zone A City centre
Floor City centre Distance from city centre Dentist Jewelry Airline Solicitor Accountant Doctor Trading Shipping Audit firm Fitness Boutique Fast food Residential Supermarket Chinese Herb Labour union Travel agent Zone A Zone B Zone C
37
Zone A is Zone B is Zone C is Central Business District Mixed land use zone Residential area
38
Central Business District
39
Characteristics of CBD
heart of city focus of major transport routes highest accessibility limited space keen competition of land use highest rent tall buildings modern buildings high order retailing business airline companies traffic congestion vertical zonation Central District Tsim Sha Tsui
40
Mixed land use Urban decay slum / poor living environment
lack of open space traffic congestion Pollution hawkers poor sanitation high crime rate
41
Mixed land use Lower buildings
vertical zonation - commercial land use occupies the lower floors residential land use occupies the upper floors higher order shops are located at main streets; lower order shops are located at side-streets factories and workshops are found in back street
42

Change of Population Density over time

44
Comparison
45
Western Vs Non-western Cities
Suburbanization counter-urbanization Rural-urban migration influx of population Good transport network Poor tarnsportation development Good economic development Poor economic development Well-developed C.B.D. Limited high order business
