本研究对内蒙古地区３４９个样点Ａ、Ｃ层土壤中１０种金属元素含量的比值进行了分析．总体而言，金属元素在内蒙古地区表层土壤中有富集的趋势，但它们在Ａ、Ｃ层土壤中含量的比值具有较大方差；偏相关分析的结果表明，土壤有机质含量、ｐＨ值和粘粒含量没有对上述比值产生显著的影响；同时，通过半方差函数的计算和空间插值对上述比值的空间结构特征进行了讨论．结果显示，研究元素在内蒙古土壤中的纵向分布没有表现出明显的空间结构，多数元素在Ａ、Ｃ层土壤中含量比值的半方差函数表现为纯块金效应．因此，内蒙古地区金属元素沿土壤剖面分布特征主要影响因素的空间变异尺度可能在本研究的最小采样尺度（大约２０ｋｍ）以下．
In this study, the ratios of 10 metal elements in soil samples from A, C soil samples of 349 samples in Inner Mongolia were analyzed. In general, the metal elements are enriched in the surface soil of Inner Mongolia, but the ratios of their contents in the soil layers A and C have larger variance. The results of partial correlation analysis show that the contents of soil organic matter, pH and viscosity The grain content did not significantly affect the above ratio. At the same time, the space structure characteristics of the ratio were discussed by means of semi-variance function and spatial interpolation. The results showed that the longitudinal distribution of the research elements in the soil of Inner Mongolia did not show obvious spatial structure. The semivariance function of the ratio of the content of most elements in the soil layers A and C showed a pure block gold effect. Therefore, the spatial variability of the major influencing factors of metal elements along the soil profiles in Inner Mongolia may be below the minimum sampling size (about 20 km) in this study.
