SPATIAL ANALYSIS OF HOUSES' PRICE IN DONGGUAN BASED ON ESDA AND KRIGING TECHNIQUES
使用普通克里金方法模拟东莞房价的空间分布,并用ESDA技术分析其空间自相关性和变异性,发现房价存在显著全局自相关、局部聚集与分散模式以及各向异性。
Property price and its spatial distribution is a hot topic in many applications.This paper explores and simulates the spatial distribution of property price in Dongguan using the ordinary Kriging method,and analyzes its spatial autocorrelation and variability using the techniques of ESDA.The conclusions from the analysis include: 1) proper price exhibits significant global spatial autocorrelation and overall clustering pattern;2) houses' price often has local clustering pattern,and sometime has local dispersed patterns owing to spatial heterogeneity;3)it can be found that the spatial distribution of proper price takes on a zonal anisotropy by semivariogram functions figures of different directions.This means that there were different structural characteristics in different directions for property price distribution;4) there is significant difference of the property price between districts.
