Models Of Urban Land Use

  1. 1. Models of Urban Land Use
  2. 2. Economic Rent <ul><li>Why are high rises in the centre of cities? Because that is where land is most expensive. </li></ul><ul><li>Each individual square metre has to be used for maximum profit. High rise buildings help solve this. </li></ul><ul><li>Economic rent decreases as you travel from CBD. </li></ul>
  3. 3. Concentric Zone Model (Burgess) <ul><li>Different zones based on economic rent and maximising profit from land. </li></ul>
  4. 4. Concentric Zone Model <ul><li>Very simple pattern of concentric circles. </li></ul><ul><li>Stop and Think </li></ul><ul><li>Can you think of factors which add complexity to such a simple model? </li></ul>LAND/TOPOGRAPHY TRANSPORT ROUTES WATER BODIES PLANNING
  5. 5. Sector Model (Hoyt) <ul><li>Similar to concentric zone model but with wedges of similar land use along transport lines. </li></ul>
  6. 6. Sector Model <ul><li>Shows more complexity than Burgess’ model. </li></ul><ul><li>Recognises that cities can change – new transport routes can alter the morphology and land use. </li></ul><ul><li>Stop and Think </li></ul><ul><li>What is the advantage of locating a business on a main road? </li></ul><ul><li>What are some examples of sectors of industry and retail radiating along the main roads in Wagga? </li></ul>
  7. 7. Multiple Nuclei Model (Harris/Ullman) <ul><li>More complex model involving the development of urban areas around pre-existing villages. </li></ul>
  8. 8. Multiple Nuclei Model <ul><li>Each village will develop on economic activities and social attractiveness. </li></ul><ul><li>More than one CBD, although one will be dominant </li></ul><ul><li>Stop and Think </li></ul><ul><li>How does Canberra fit the multiple nuclei model? </li></ul><ul><li>Where are Wagga’s secondary nuclei located? </li></ul><ul><li>Why do you think they are there? </li></ul><ul><li>Which one is likely to grow the most in the future? Why? </li></ul>
  9. 9. Urban Ecology Structure (Murdie) <ul><li>Complex interaction of housing, ethnicity, economic activity and physical space. </li></ul>
  10. 10. Urban Ecology Structure <ul><li>Ethnicity – cells of different ethnic origin eg. Vietnamese in Cabramatta, Jewish in Eastern Suburbs </li></ul><ul><li>Residential – Housing (and usually families too) get younger the further from the centre. </li></ul><ul><li>Economics – Sectors of different commercial, industrial and services aggregated from centre. </li></ul><ul><li>Physical – infrastructure, topography and water bodies. </li></ul>
