SPATIAL AUTOCORRELATION OF URBAN LAND PRICE:A CASE STUDY OF SUZHOU
利用全局和局部空间关联指标及变异函数，全面探索了苏州商业和住宅用地价格的全局与局部空间自相关及各向异性特征，发现地价在约2800米阈值内呈显著正相关，且南北方向相关性更强。
By using of global and local spatial association indicators and variograms,global and local spatial autocorrelation and anisotropic features of commercial and residential land prices in Suzhou were comprehensively explored.The results indicate that with the thresholds of autocorrelations about 2800m, commercial and residential land prices in Suzhou present significant positive autocorrelation and tend to higher clusters,the autocorrelation is inverse with distance while semivariogram grows by spheral model.Spatial autocorrelation of land price is difference in different direction and the contingency in north-south direction where the threshold is larger,is stronger than that in west-east direction.While land prices show significant autocorrelation in global scale,most land prices present local clustering pattern but there is still some heterogeneity in some area.
