摘要:

随着社会主义市场经济体制的不断完善,城市建设越发需要有章可循。城市土地的合理配置是城市发展的重要环节,其基础性工作之一--城市基准地价评估更是作用显著。在对传统地价评估方法和常规克里格方法进行总结及评析的基础上,提出了基于第二信息源的协同克里格方法,并对其预测结果和精度加以全面分析,最后详细解读了由该方法反映出的地价空间结构特征。实证研究表明:克里格方法与反距离加权法相比,在预测及校准误差方面有着明显的改善;协同克里格法在均方差精度指标上更显优越性。因此,协同克里格法更具实用性和科学性,可以广泛应用到各级城市地价评估工作中。

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.
