Conurbations:

a group of towns that have spread and joined

together to form an area with a high population,

often with a large city as its centre

Edge cities (Garreau, 1991)

1. The area must have more than 4.5 million square meter of office space(about the space of a good-sized downtown) 2. The place must include over540,000 square meter of retail space(the size of a large regional shopping mall)

3. The population must rise every morning and drop every afternoon (i.e., there are more jobs than homes)

Urban growth boundary

• A planned capacity to accommodate a 20-year forecast of housing needs and employment growth, if the area affected by the boundary

Threshold analysis

•

Created by Malis (1960), an area delineation based on land

suitability

•

Developed by using location-oriented technique that has

already counted threshold cost in developing region

•

Threshold cost equals to grade cost (land construction) and

stepped cost (limited infrastructure services)

•

Recently, threshold consider ecosystem services cost and

Why we need the threshold index

•

To anticipatively measure the needs of

infrastructure and to ensure the basic

infrastructure well-provide and right on time

•

To al ulate the additio al i frastru tures or

•

To provide assurance to the private sectors in

deciding their investment

•

To have a good quality of space production, ensure
