城镇土地定级中定级因素因子作用分值计算难度较大、情况复杂、计算量大,特别是有阻隔存在情况下更是如此.作用分值计算直接影响定级成果的精度.以达州市城市土地定级为例,讨论栅格数据空间分析方法在定级因素作用分值计算中的应用.结果表明,栅格数据空间分析方法可以用于计算定级要素作用分值;特别在有阻隔存在的情况下,能够提高定级效率和定级成果的精度.
A Study on the Score Calculation of Grading Factor Effect in the Presence of Barriers
In urban land grading, it is rather difficult and complex to calculate the effect of grading factors with tremendous calculation work, especially there exist some barriers. The calculation of factor effect has a direct effect on the accuracy of the grading results. In this paper, the grading of urban land in Dazhou City of Sichuan Province is taken as an example to discuss the application of grid data space analysis method in the score calculation of grading factor effect. The results show that grid data space analysis method can be applied in calculating the effect of grading factors. It can promote the efficiency and accuracy of grading result in the presence of barriers.
