摘要
用等离子直读光谱仪测定了山东省５种有代表性土壤中１５种稀土元素的含量。测定结果表明，山东省土壤中稀土元素含量以轻稀土元素为主，轻稀土元素含量占稀土元素总量的７６．２％～８０．４％。镧系元素的含量依各元素的原子序数呈奇偶分布，从Ｌａ到Ｌｕ元素分布呈波浪式下降趋势，这与地壳中镧系元素丰度和原子序数间的关系是一致的。
Five of the fifteen rare earth elements in Shandong province were determined with Plasma-direct legible spectrum apparatus. Results show that most of the fifteen RE elements in the province are light ones, account for 76%～80%.The content of the elements in lanthanide series are basically magatively proportional to their atomic numbers. From La to Lu, the proportion of the elements show a wavy dicline tendency, which appears to be the same as the relation between the clark values of lanthanide elements and their atomic numbers.
