对发育在Ｑ＿３、Ｑ＿２母质上的典型土壤及其剖面进行研究。结果表明，土壤有明显的粘化现象，游离氧化铁均小于２％，粘土矿物以２：１型为主，有大量铁质凝固、结核和粘粘胶膜。Ｑ＿２母质土壤较Ｑ＿３母质土壤的粘粒硅铝率小，并含有较高的Ｆｅｄ，风化淋溶系数亦稍低，保留了其残遗特征，但仍进行着与现代生物气候条件相协调的形成过程。本文还对供试土壤的分类归属进行了探讨。 The typical soils and their profiles developed on Q_3 and Q_2 parent materials were studied. The results show that the soil has obvious sticking phenomenon, the free iron oxide is less than 2%. The clay minerals are mainly 2: 1 type, with a large amount of iron coagulation, tuberculosis and sticky adhesive film. Q_2 parental soil had smaller clay-silica-alumina ratios than Q_3 parent soil, higher Fed content, and slightly weathered leaching coefficients, which retained its remnant features but were still in harmony with modern bioclimatic conditions process. This paper also discusses the classification of soil for testing.
