摘要:
以宁夏固原县上黄村和云雾山自然保护区为研究对象，通过大量的室内分析，研究其土壤中矿质元素的剖面分布状况及其氧化铁的分布特征。结果表明供试土壤土体中矿质元素的含量顺序依次为SiO2>Al2O3>CaO>Fe2O3>K2O≈MgO>TiO2>MnO2。其中硅、铝、铁的在剖面上分布较均匀，钙、镁、钾变异较大，空间分布不均；钛、锰空间变化较小，说明供试土壤处于物理风化阶段，土壤的化学风化程度较弱。氧化铁全量含量变化不大，其剖面各层的游离铁、活性铁和络合铁含量均不高，且空间变化幅度小，表明供试土壤的铁的淋溶状况不明显，土壤风化发育不好，释放出的氧化铁少。
Abstract:
Based on field investigation and analysis, the soil minerals compounds and ferric oxide in hilly-gully area of Southern Ningxia were studied, including Shanghuang experimental area and Yunwu mountainous area. The results showed that the contents order of soil bulk mineral elements are SiO2>Al2O3>CaO>Fe2O3>K2O≈MgO>TiO2>MnO2. Si, Al and Fe are evenly distributed in soil profile, Ca, Mg and K are not so even which are higher in up layer than suborder layer. It also showed that the soil genetic develop in the stage of physical weathering, the chemical weathering is not so strong. The total contents of ferric oxide didn’t change so abruptly in different soil layers, which showed the Fe weathering was not so obvious.
