本文对51个测点各两个层次几种土壤特性进行了空间变异分析。结果表明在不考虑样点位置时,土壤饱和导水率呈对数正态分布,而两个层次的土壤粘粒、粉粒、不同粒径的微团聚体和有机质含量均呈正态分布。空间变异结构分析表明,两个层次的土壤粘粒、粉粒、微团聚体含量是空间自相关的(除表层<0.002mm微团聚体)和空间交互相关的。
In this paper, spatial variability analysis of several soil characteristics in two levels of 51 measuring points was carried out. The results show that soil saturated hydraulic conductivity shows a lognormal distribution without taking into account the location of the samples. Soil clay, silt, and different sizes of microaggregates and organic matter in two levels show a normal distribution. Spatial variability analysis revealed that soil clay, silt, and microaggregates were spatially correlated with spatial autocorrelation (excluding <0.002mm microaggregates) in the two levels.
