摘要
土壤空间变异作为土壤科学研究中的热点,引起了广泛的关注,但其定量描述一直困扰着土壤学家。然而随着空间分析方法的引入,土壤变异的定量化程度将得到提高。常用的空间分析方法有地统计学、空间自相关分析、分维数分析、趋势面分析、尺度方差分析等。为此,介绍了这些方法的基本原理,并比较各种方法在土壤变异研究中的优缺点。
Soil spatial variability, as research focus in soil sciences, has caught wide attention, but its quantitative description has been perplexing the penologists all the time. With the spatial analytical method applied in soil spatial variability, the quantitative degree will be promoted further. General spatial analytical method include geostatistics, spatial autocorrelation, fractal dimension, trend surface analysis, scale variance analysis. This paper will introduce the basic theory of these methods one by one and compare one＇s own characteristic in soil spatial variability, as research.
