土壤性质的变化幅度可能会因地而异，这种缺乏平稳性的情况可能会妨碍常规的地质统计和频谱分析。相比之下，小波及其尺度函数只在短间隔内取非零值，因此是局部的，使我们能够处理这种变化。在协区域化的线性模型不成立的情况下，小波可以用来分析尺度依赖性和两个变量相关性的空间变化。
The magnitude of variation in soil properties can change from place to place, and this lack of stationarity can preclude conventional geostatistical and spectral analysis. In contrast, wavelets and their scaling functions, which take non‐zero values only over short intervals and are therefore local, enable us to handle such variation. Wavelets can be used to analyse scale‐dependence and spatial changes in the correlation of two variables where the linear model of coregionalization is inadmissible.
