土非代换性钾在剖面分析特征，拟合是一个非线性方程，并以此可对 土进行初步的系统分类，初拟对５个剖面可分为三个类型。图中Ａ部位反映了 土肥熟堆垫表层（或者 化过程）中土壤非代换性钾的变化状态，表现为耕作层（现代）高，以下土层则逐渐降低，这和肥熟堆垫过程，栽培作物的吸收，迁移和富集等土壤生态环境有关．也表明了在植物参与下 土剖面的非代换性钾耗竭、富集与成壤过程的同步性和异空间性。
Soil non-substituted potassium in the profile analysis of features, fitting is a nonlinear equation, and thus the initial classification of the soil system, initially proposed five sections can be divided into three types. Part A of the figure reflects the change of soil non-substituted potassium in the surface layer (or process) of soil matured heap, showing that the tillage layer (modern) is high while the soil layer below is gradually decreasing. , The absorption of cultivated crops, migration and enrichment of soil ecological environment. It is also indicated that the non-substitutional K depletion, enrichment and soil-forming process of soil profile with the participation of plants are synchronous and spatial.
