| 为揭示城市商业用地地价的微观分布规律,基于区域化变量理论和地统计学,以呼和浩特市为例,采用半变异函数分析商业用地地价空间连续及变异特征,用普通克里格插值方法模拟商业用地地价空间分布,生成地价模拟图。结果表明:商业用地样点地价兼具空间自相关性和各向异性,但受区域整体趋势的影响明显强于小范围的变异性;商业用地地价分布整体具有连续性,局部具有突变性;等价线分布呈现圈层结构,但地价越高的区域面积越小;交通道路对商业用地地价分布有重要影响,城市扩展会带动扩展方向的区域商业用地地价升高;商业用地地价从市中心向外围呈指数递减。 |

| Modeling and analyzing urban commercial land value: Huhhot City as a case study |

| Abstract: |
| To find out the microcosmic distribution rules of commercial land value,this research was conducted based on the regionalized variety theory and geostatistics.Taking Huhhot as a case study,semivariograms were used to analyze spatial continuity and variability of commercial land value,Ordinary Kriging interpolator to model distribution of commercial land value and achieves modeled map of commercial land value.The results show that commercial land samples' value take on spatial autocorrelation and anisotropics,are impacted by regional total trend more than little-range variability;land value takes on continuity in general and variability in local;land value isolines take on circles structure,but higher value regions having littler area;urban roads and streets have important impacts on land value,city expanding can heighten land value in the regions of expanding directions;commercial land value descends exponentially from city center to city periphery.The method and conclusions of this paper maybe used for reference to relative research. |
