顾及地价空间分布规律的城市基准地价以价定级方法研究

Price Based Method for Land Grading and Benchmark Land Price Evaluation Considering Spatial Distribution of Land Price

提出了一种城市基准地价以价定级方法。该方法用矢栅混合模型划分评价单元,对地价样点进行趋势面分析筛选,使用最短路径距离代替欧氏距离对地价样点进行空间插值,叠加分析后得到各评估单元的指标地价,用其代替传统的因素综合得分对基准地价评估区域分等定级,同时测算出各级别基准地价。以上海市为例对该方法的实用性进行了验证。

We propose a new price based method for land grading and benchmark land price evaluation.Vector-grid hybrid model is used to dicide the assessment cells.Firstly,we use trend surface analysis model to eliminate abnormal samples.Then shortest path distance is used instead of Euclidean distance to do the interpolation of sample points.After the overlay analysis,we do some statistical analysis to decide the land grade and get the benchmark land price for each grade.At last,we take the city of Shanghai as an example to show the practicality of our method.
