摘要
针对城镇基准地价更新中土地级别范围调整问题,提出了运用数字地价模型去调整土地级别,用已交易的土地价格数据为前提,在ArcView系统支持下,选择合理的空间内插模型,将区域的交易地价点进行栅格化处理,可以生成三维地价模型,直观地再现了土地价格格局,内插计算出该区域内每一个单元的地价,然后根据一定的地价幅度生成土地级别图,与原有的土地级别对比,进行土地级别范围的确定和调整。
In this research,the digital land price model was proposed to adjust the land grade based on the problem of benchmark price during rectify the land grade.Chose the reasonable interpolation method and then make grid treatment,the three-dimension land price model was obtained using the bargaining land price,which supported by the ArcView.The model provided the structure of land price.The price of each unit was calculated after interpolation,then the map of the land grade was estimated that compared with the original to make adjust.
