In order to know how and why the land values changed inside the city

the land-value patterns of Beijing during the period from 1998 to 2005 were studied based on Kriging and GIS Method.The land-value data of Beijing had a second order trend

so the Ordinary Kriging(OK) method was used after removing the trend surface.The results showed that there was a positive relationship between land-value and ring roads.The patterns of land values were clearly affected by the eradiating function of the city centre

and there was no independent sub-centre formed.In addition to the impact of city center

the main reasons for the land value increase were the influence of city planning

the expected appreciation

and improvement of infrastructure and transportation.In the process of suburbanization of Beijing

the land values showed a significant growth pattern from the near suburban to the city centre

which caused by the restraint of land resources.
