【摘要】：基于地統(tǒng)計(jì)內(nèi)插構(gòu)建數(shù)字地價模型是目前國內(nèi)研究地價空間分布的常用手段。既往的研究大多側(cè)重空間變異分析或不同模型結(jié)果的比較,較少探討一個完整的建模過程及過程中一些重要參數(shù)如何科學(xué)選擇與設(shè)置。文章以2008—2014年石家莊市主城區(qū)土地交易數(shù)據(jù)為例,借助ArcGIS、GS+軟件平臺,深入探討了基于地統(tǒng)計(jì)學(xué)原理,利用Kriging插值的方法,構(gòu)建數(shù)字地價模型的完整過程,并重點(diǎn)探究此建模過程中獲取最優(yōu)參數(shù)的方法。結(jié)果表明:基于地統(tǒng)計(jì)方法構(gòu)建的數(shù)字地價模型,能夠合理地模擬區(qū)域地價空間分布形態(tài);并通過探索性空間數(shù)據(jù)分析、變異函數(shù)分析、不同模型擬合優(yōu)度對比、交叉驗(yàn)證精度檢驗(yàn)等手段,有效地保證了建模參數(shù)的科學(xué)性和準(zhǔn)確性。
[Abstract]:To construct digital land price model based on geostatistics interpolation is a commonly used method to study the spatial distribution of land price in China at present. Most previous studies have focused on spatial variation analysis or comparison of the results of different models. This paper takes the land transaction data of Shijiazhuang City from 2008 to 2014 as an example, and discusses the principle of geostatistics based on ArcGISGS software platform. Using the Kriging interpolation method, the complete process of constructing the digital land price model is discussed, and the method of obtaining the optimal parameters in the process of the model is studied. The results show that the digital land price model based on the geostatistics method is constructed. The spatial distribution of regional land price can be simulated reasonably, and by means of exploratory spatial data analysis, variance function analysis, comparison of goodness of fit of different models, cross-validation accuracy test, etc. The scientific and accuracy of modeling parameters are ensured effectively.
