A Research into Urban Land Gradation with the Method of Gradation Based on Price:Taking Nanbu City in Sichuan Province as an Example

On the basis of a comparison between major methods adopted in urban land gradation,this paper analyzes how the urban land in Nanbu county of Sichuan Province has been graded.The gradation follows the process of determining different land price sections,calculating and adjusting sample land prices,and adopting the cluster analysis of land price sections to grade the land.We compare the land gradation result got by the method of gradation based on price with that got by the method of multi-factor comprehensive analysis to work out the difference between them,to find out the factors attributing to their differences,and to prove the reliability of the former observations.By this,the present study intends to provide an example of how to apply the method of gradation based on price to the gradation of the land in small towns.
