Abstract:

Urban Land shows a different development pattern under the combined effects of the driving forces. Taking Qianxi county as a case, this paper uses extreme standardized method to deal with the county's eight townships driving forces indicator data and classifies the driving forces effects according to the total scores. Based on a system of urban land quality driving forces analysis layers, superposition analysis has been done on the basis of the land classification map and the factor scores level layers using Geographic Information System (GIS) technology. The result shows that the effect degrees and mining potential space of driving forces to land quality are different. Land production potential and basic establishment influence the land quality most distinctly, and they distribute from the lowest mining potential to higher mining potential on 4 standards. Urban location and urban convergency scale influence the land quality more distinctly. Urban location distributes from mining potential moderate to the highest mining potential, and urban convergency scale distributes from lower mining potential to higher mining potential on 3 standards. Regional economy develop level and integration service ability don't influence the land quality distinctly. Regional economy develop level is in mining potential moderate and higher mining potential, and integration service ability is in lower mining potential and mining potential moderate on 2 standards.The different of driving forces spatial effects reflects the strength or weakness of the urban on this aspect, and can guide the urban construction.
