摘要:
文章针对局部Moran’s I值的计算公式，通过选取不同的尺度d，采用三种不同的标准化处理方法构造出不同的空间距离权重矩阵，求得相应的局部Moran’s I值。最后基于尺度的变化，对局部Moran’s I值进行显著性检验，检验结果表明尺度变化对局部Moran’s I值的变化的影响是显著的，证明了局部Moran’s I的值对尺度具有依赖性。
The paper focuses
on the calculation formula of local Moran’s I, and uses three standardized
processing methods to construct different spatial distance weighted matrix by
choosing different scale d, thus the corresponding values of local Moran’s I
are obtained. Lately, the significance testing of local Moran’s I is proceeded
based on changeable scales, and the testing result is positive. So, the values
local Moran’s I are dependent on scale.
