摘　　要：对我国东部平原土壤微量元素共生组合特征及含量预测的研究表明，第四周期过渡元素之间、亲铜元素之间具有较好的相关关系；采用Ｌｏｇｉｓｔｉｃ生长曲线处理的结果表明，在我国华北平原及其周围地区可对土壤的微量元素含量作出较为准确的预测，而在长江及其以南地区，只能得出大致的含量估计。Trace element associations and their content prediction in the soils from eastern China plains were studied.The results show that there is significant statistical correlation between the transitional elements from the 4th period of the Periodic Table and between the chalcophile elements.Most elements indicate significant dependence on the contents of the <0.01mm particles in soil,and some have correlation with the pH value and the content of organic matter.The S-curve model can be used to predict trace element contents,and the prediction is quite good in North China,but not in South China.
