摘  要：
通过野外调查采样、室内化学分析等方法,研究了吉林省中部不同亚类黑土(3个亚类,5个剖面)铁、锰的含量及垂直分布规律,分析了成土母质、成土过程、成土环境对铁、锰含量及分布的影响。结果表明:红土母质中全铁含量均高于黄土母质,而黄土母质中全锰含量较高。全铁在黄土母质的典型黑土和白浆化黑土中表现为表聚和淀积特征,在草甸黑土中差异很小;有效铁在红土母质中分布规律与全铁相反,在草甸黑土中表现出明显的淀积特征,其余各土类中有效铁含量分布与全铁一致。全锰在典型黑土中呈从上至下逐渐减小的规律,在草甸黑土中表现出较弱的淋溶特征,在白浆化黑土中表现出较明显的表聚和淋溶淀积特征。有效锰在草甸黑土中差异不大,在白浆化黑土和典型黑土中有很强的表聚特征。有效锰与有机质呈显著正相关(r=0.526,n=19)。

摘  要：
Vertical distribution regularity of Fe and Mn and their content in different subgroups of black soil in the middle part of Jilin province (three subgroups and five profiles) were studied, by means of filed work, chemical analysis, etc. The results showed that the tested trace elements had different distributions in different parent material profiles and soil types. Red parent material had high content of total Fe while loess parent material had high content of total Mn. Total Fe had surface accumulation and illuviation in loess parent material typical black soil and albic black soil. Available Fe, on the other hand, had obvious illuviation in meadow black soil. Some other available Fe had the same rule with total Fe. Total Mn had the rule of decreasing from upside to downside, and it had strong leaching in meadow black soil. In albic black soil, it had obvious surface accumulation and leaching illuviation. Available Mn had little change in meadow black soil, but in albic black soil and typical black soil it had strong surface accumulation. Available Mn was positively correlated with organic matter (r=0.526,n=19).
