摘要:

本文针对目前农用地定级研究中对空间扩散因素作用分值量化方法不尽合理的问题,对空间扩散因素作用分值量化模型进行阐述,建立基于Voronoi 图的农用地空间扩散因素(点和面状因素因子)距离衰减模型,然后利用该模型计算各空间扩散因子对定级单元的作用分值,从而为准确进行土地定级提供初步依据。

Abstract:

This paper, based on the issues of irrational quantitative spacing attenuation of farmland, expands the spatial diffusion quantization model, establishes a farmland spacing attenuation model based on Voronoi diagram (point and plan factors), and applies it to calculate the effective scores of each spatial diffusion factor to grading units.

Key words:

farmland; Voronoi diagram; diffusion factors
