摘要
研究了北亚热带地区7个白浆化土壤的元素化学组成,认为土壤的地球化学特征深受母质的影响.主组元分析表明,成土过程中元素的迁移程度以铁和锰最为活跃,钛相对稳定,而钠、钾、硅和镁等元素易淋失.
The chemical elemental components of seven albic soil profiles are analysed. It is concluded that the soil geochemical properties are affected deeply by parent materials. The main component analysis shows that Fe,Mn and Al are very active,Na,K, Si and Mg can be leached,Ti is relatively inactive. The fact that the Sa,Saf and ba values in albic horizons are higher than in illuvial horizons shows that the upper horizons were wheathered strongly.
