山西土壤稀土元素背景值

在山西省内根据主要土壤类型布设典型剖面１５个，分层采集土壤样品，测试分析其中稀土元素的含量。经统计分析，获得了山西省土壤中１５个稀土元素背景值。与中国土壤和世界土壤稀土元素背景值比较，均无显著性差异，且均在世界土壤稀土元素含量范围之内。

The Rare Earth Element Background Values of Soil in Snanxi

The authors laid out 15 typical soil profile samples from different areas throughout Shanxi,which were treated by modern analytic method and mathematical statistics,and at last,the 15 soil rare earth element background values were obtained.Comparing the soil rare earth element background values in Shanxi to those in China, there are no obvious differences for all 15 elements and to those in the world, the soil rare earth element background values are in the world's range.
