Abstract
Most cities in China have adopted graded land price to represent standard land price so far, while others have employed route price and district price. All of the methods mentioned above only show the average price in a region, which are not easy for the public to understand. The emergence of grid standard land price enhances the publicity, simplifies the process of parcel evaluation and lessens the extent of artificial interference. There are two methods to generate grid standard land price. Firstly, all grid point standard prices are calculated by establishing the relationship between the land price and graded score. This relationship can be obtained through regression analysis of graded results and the sample land price. The second method is DEM-based numerical surface rebuilt technique. It is a 3D grid model established by spatial interpolation among monitoring samples acquired by collecting market exchange price samples and the samples from land price monitoring survey. Considering the characteristic of Guangzhou City, this paper provides a method to generate grid standard land price based on Thiessen polygon interpolation method and compares it with other interpolation methods to prove its effectiveness.
