| 摘 要： | This paper has investigated the ratios of closely related elements such as Mn, Cr, V, Ni, Co, Cu, Pb, Cd, Ba, Sr, La and Ce in the major soils of China, and the factors affecting them, and explored their use as indicators in soil formation, material transport and environmental pollution. Results show that the effect of soil-forming processes on the ratios of closely related elements varied with different elements, and became greater in the sequence of Ce/La <V/Cr=Ni/Co<Zn/Cu=Zn/Pb<Zn/Cd <Mn/Cr <Ba/Sr. The magnitude of the variation in the ratios of closely related elements depended on the chemical properties of the elements themselves, on the one hand, and the parent material and climatic conditions on the other.
