用因子克里格法分析了内蒙地区土壤中 1 0种微量元素含量的空间结构特征。结果显示 ,母质和以土类为代表的表生地球化学作用是影响内蒙土壤中微量元素含量空间分布模式的主要因素。母质因子的空间变异尺度较小 ,而表生地球化学作用因子则具有较大变异尺度。整体而言 ,母质的影响强于表生地球化学作用。内蒙土壤中微量元素含量在不同空间尺度具有较为一致的相关特征。取决于离子半径的类质同象作用是形成特定相关特征的重要原因
The Kriging method was used to analyze the spatial structure of 10 trace elements in soils of Inner Mongolia. The results show that the parent geochemical and epigenetic geochemical processes represented by soil are the main factors affecting the spatial distribution patterns of trace elements in Inner Mongolia. The parental factors have a smaller scale of spatial variability and the epigenetic geochemical factors have a larger scale of variation. On the whole, the effect of parent material is stronger than epigenetic geochemistry. The contents of trace elements in soil in Inner Mongolia have consistent characteristics at different spatial scales. Homomorphic effects, which depend on the ionic radius, are important reasons for the formation of a particular related feature
