摘　　要：以福建省厦门市2004年岛内住宅用地监测点地价为例,利用离散点(地价样点)建立基于规划网的数字地价模型.采用Surfer和ArcGIS两种地理信息处理软件,对少量监测样点进行插值,形成连续地价曲面,分别从等高线等空间特征概念对比分析两种数字地价模型的优缺点.研究表明:Surfer软件功能较单一,只能对样点进行一次插值,形成简单的数字图形,未生成可视的地价连续曲面;而ArcGIS可以对样点地价的第一次插值结果再一次插值,使地价点更密集,形成的地价曲面更平滑、准确.Taking a residential land on the island of Xiamen in 2004 as an example,the digital land price model was established through land price samples.Using Surfer and ArcGIS,software of geographic information,interpolating several samples to form a continuous surface of land price,the property of two the digital land price models was discussed through the comparison of space concept,such as isolines.The results indicate that Surfer can only interpolate once and make a simple map which is not a visual and continuous surface.However,the ArcGIS can provide second interpolation by the record of first time to increase the land price samples and make the land price surface more accurate and smooth.
