内蒙阿拉善地区植物、土壤的元素背景特征及其相互关系的研究结果表明：５３种植物的９种元素（Ｚｎ、Ｃｕ、Ｎｉ、Ｐｂ、Ｃｄ、Ｃｏ、Ｃｒ、Ｖ、Ｍｎ）背景含量有很大差异．不同生活型植物背景值也各异，总的规律为：Ｍｎ＞Ｚｎ＞Ｖ＞Ｃｕ＞Ｎｉ＞Ｃｒ＞Ｐｂ＞Ｃｏ＞Ｃｄ；同种植物的元素含量在不同群落中有明显差别，但都在同一个数量级．土壤９种元素的背景含量均以Ｍｎ含量最高，其次为Ｚｎ和Ｖ，Ｃｄ的含量最低；不同上类各剖面各种元素的垂直分布规律为底层或表层的元素含量高于中间各层．土壤元素背景值都高于植物背景值，前者一般为后者的２～２０倍．植物对元素的吸收系数以Ｃｄ最大，Ｃｒ最小．土壤元素含量与有机质含量的相关性因土类不同而异：沙土的有机质含量最低，只有Ｚｎ含量与有机质相关性显著；而盐土的有机质含量最高，有Ｃｏ、Ｃｄ、Ｍｎ、Ｎｉ、Ｃｒ、Ｚｎ６种元素含量与之显著相关．
The elemental background characteristics of plants and soils in the Alxa area in Inner Mongolia and the correlation between them show that the background contents of nine elements (Zn, Cu, Ni, Pb, Cd, Co, Cr, V, Mn) Big difference. Different living plants also have different background values. The general rules are: Mn> Zn> V> Cu> Ni> Cr> Pb> Co> Cd. The same order of magnitude. The contents of 9 elements in soil were the highest in Mn, followed by Zn and V, and the lowest in Cd. The vertical distribution of the elements in the upper and lower layers was higher than that in middle layer. The background value of soil elements are higher than the background value of the plant, the former generally 2 to 20 times the latter. Absorption coefficient of plant elements to Cd maximum, Cr minimum. The correlation between soil element content and organic matter content varies with different soil types: the content of organic matter in the soil is the lowest, only the correlation between Zn content and organic matter is significant, while the content of organic matter in salt soil is the highest, with Co, Cd, Mn, Ni, Cr and Zn6 Significantly related to the elemental content.
