STUDY ON THE APPROACH TO URBAN LAND CLASSIFICATION
设计了一种整合多因素评价法和市场交易价格评价法的城市土地分类技术路线，并讨论了权重、空间插值等关键问题，通过案例展示了GIS支持下的应用流程。
The multi-factors appraisal method and market transaction price appraisal method,which are based on the grid unit and the isotropic unit respectively,are two kinds of common techniques applied to urban land classification.This paper designs one kind of technical approach to urban land classification.It integrates the two methods mentioned above and considers urban land evaluation as the penetration and measurement of urban land classification.On the basis of this,certain key issues,such as the weight of multi-factors appraisal,spatial interpolation of parcel pricing,the relation between grid synthesis score and the land price of specimen,the service radius of factors function,the attenuation model of factors function and so on,are discussed in technical approach designed.A case is used to demonstrate systematically the application procedures of technical approach which designs and lays emphasis on how to carry on the comparative analysis on the methods for multi-factors appraisal and market transaction price appraisal with support by GIS technology,as well as the actual problem in the operation emphasized.
