Transcript of Main concept of the Models
Does Von Thunen Theory or Sinclair Theory explain the agricultural pattern in Pak Kong ?
Main concept of the Models
Von Thunen Theory~ stress the distance from the market & the tr
ansport cost• Near to the market (transport cost)• Far away from the market (transport cost)• Near to the market (the intensity)~ There is a negative relationship between th
e distance from the market & the intensity
0 Distance from the mkt.
Intensity
Von Thunen Model
Sinclair Model
• Competition between urban land use &farming land use
• Value of agricultural land use• Location rent of urban & agricultural use• Distance increase relationship~Production intensity increase with increasing
distance from the market(urban city)
Value of agricultural Land Use
Distance from the mkt.Expanding city

After integrated area A,B,CWe have the following conclusion
Sinclair Theory• In Pak Kong ,there are lots of abandoned la
nd ~ Urban encroachment ~ The farmers are waiting for the gov’t/privat
e developers to buy the lan
• Pak Kong is not a static single market ~ The crop is for serving all area in HK ~e.g. there is market gardening for serving banks and
hotel in Area A• Many abandoned farmland are near the main road &
some are using for farming are not nearby it ~ The reduce of relationship between transport cost and
the profit• Some farmland are changed into residential or
industrial land use ~ vacant land ~ commuter ~ urban encroachment
Von Thunen • Sai Kung can be separated into the area of r
ing 1 when the urban area is the market• Most farming activities in Pak Kong is mar
ket gardening • The distance from the market also affect the
transport cost
The two models are ignored the perceptions of the farmers so that they are partly suitable for explaining the land use pattern of Pak Kong.
