对第四纪河湖沉积物母质发育成的３个暗棕壤土亚类、６个草甸土及白浆土亚类剖面氧化稀土总量和可溶态稀土总量进行了测试分析。结果表明，氧化稀土总量与可溶态稀土总量的含量呈正相关，与ｐＨ值未有明显相关性，而暗棕壤土类可溶态稀土总量与ｐＨ值呈明显负相关。从剖面分布看，随着层次加深可溶态稀土总量提高，但达到基层母质时又有降低的趋势，其含量变化呈现出不规则的正态分布.
The total amount of rare earth oxides and soluble rare earths in three sub-clayey soils, six meadow soils and albacore clays developed from the parent material of Quaternary sediments were tested and analyzed. The results showed that there was a positive correlation between the total amount of rare earth oxides and the content of soluble rare earths and no significant correlation with the pH value. However, the total amount of soluble rare earths in dark brown soil was negatively correlated with the pH values. From the distribution of profiles, the total amount of soluble rare earths increased with the deepening of the stratification, but decreased when reaching the parent material of the grassroots. The changes of the contents showed an irregular normal distribution.
