| 摘 要： | 研究福建4条代表性山地土壤垂直带谱中铁的形态的结果表明,氧化铁的活化度和游离度随海拔升高而呈现规律性的变化,应用主组元分析法,前两个主组元全铁和游离铁的累计贡献率已达85％以上。据此认为,氧化铁的活化度可以作为划分常湿润铁铝土亚纲和湿润铁铝土亚纲的一项参考依据。

| Abstract: | Different forms of iron oxides of four vertically distributed spectra of mountain soils in Fujian Province were studied.The degree of activation and the degree of segregation of iron oxide varied with the variation of altitude.The result of principal component analysis showed that the accumulative contribution of the first two principal component was more than 85% (Fe_t and Fe_d).Therefore, it is considered that the degree of activation of iron oxide can be used as an refereutial index for classifying peruelic ferrallisols and udic ferrallisols. |
