在野外考察和室内分析的基础上，针对当前塿土分类中存在的主要问题，探讨了人为活动对土壤形成发育的影响。认为 土由于人工熟化培肥过程，形成了巨厚的人工覆盖层和粘化层，产生二次复钙现象，土壤风化发育处于脱盐基的硅铝化阶段，幼年性特征明显。最后提出塿土作为独立土类的依据与标准，即若有人工覆盖层，且厚度超过５０ｃｍ，应作为一种新的土类从原土壤类型中划分出来，进行单独分类；否则，仍应归属原土类──褐土。
On the basis of field investigation and indoor analysis, the paper discussed the influence of human activities on the formation and development of soil in view of the main problems existing in soil classification. It is considered that the soil forms a thick artificial cover and sticky layer due to the artificial maturation and fertilization process, resulting in secondary recalcification phenomenon. The weathered development of the soil is in the aluminosilication stage of desalination, and the juvenile characteristics are obvious. At last, it is proposed that the soil as the basis and standard for the independent soil type, that is to say, if there is artificial covering layer and the thickness exceeds 50cm, it should be classified as a new soil type from the original soil type and classified separately; otherwise, Native soil ─ ─ cinnamon.
