摘要
对供试土壤的稀土总量(Σ REE),轻稀土含量(Σ LREE)和重稀土含量(Σ HREE)与土壤颗粒组成、有机质含量、腐殖质组成及不同形态氧化铁含量之间的相关关系进行了统计分析.结果表明:(1)ΣREE、Σ LREE 与土壤粘粒,有机质、腐殖质及组成,Fe_t,Fe_d,Fe_(d_o),Fe_(t-d)之间均呈极显著相关;(2)Σ HREE 与上述物质的相关均不显著.
The statistical analyses between content of total rare earth element(ΣREE),light rare earth el- ement(ΣLREE),heavy rare earth element(ΣHREE)and the contents of soil particals,organic matter,hu- mus,iron oxides in the soils were made.The results showed that:(1)there was significantly positive correla- tion between ΣREE,ΣLREE and the content of clay,organic matter,humus,Fet,Fea,Fe_(d-o),Fe_(t-d),and(2) not correlation between ΣHREE and the contents of soil components above was not significant.
