摘  要:
针对城镇土地定级中扩散性因子处理存在的问题,基于Dijkstra算法对最短路径衰减方法进行了改进,并以上街区住宅用地定级为实际应用案例,运用多因素综合评价法,在扩散因子处理上采用直线衰减和最短路径衰减两种方法获取结果,通过两种方法的对比,划分住宅用地定级范围,指出在土地定级中采用沿道路衰减,即最短路径衰减的合理性、客观性,并通过测算修正地价和两种方法的相关性系数,进一步说明沿道路衰减(最短路径衰减)在土地定级中应用的优越性、真实性。

摘  要:
In view of the existing problems in urban land grading,this study selected Shangjie District of Zhengzhou City as the study area,and used the method of multi factor comprehensive appraisal to improve the shortest path attenuation method based on the Dijkstra algorithm and used both linear attenuation and the shortest path attenuation to manage the diffusion factor. By the comparison of linear attenuation and the shortest path attenuation and the division scope of residential land grading,the result shows that the shortest path attenuation with rationality and objectivity along the road is used in land gradation. By calculating the correlation coefficient between linear attenuation and the shortest path attenuation and revising the land price,the paper further illustrates the advantages and the reality of the application of the shortest path attenuation in land grading.
