Abstract:

With the perfection of socialism market economic system, the urban construction needs more rules to follow. Rational allocation of urban land is an important part of urban development, and urban land price appraisal is significant. On the basis of assessment towards traditional assessment methods and conventional Kriging methods, this paper puts forward co-Kriging method with second message source, analyzes the forecast results comprehensively and interprets the structural characteristics of the land space reflected by this method. The case study has shown that Kriging has improved significantly in prediction and validation errors compared with IDW; co-Kriging method is even more accurate in the RMS. Therefore, the method has a relative strong scientificness and practicability and can be widely applied to all levels of city land in the assessment.

Key words: cokriging, Shishi, spatial structure, standard land price
