| 摘 要： | 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。 |

| Abstract: | Based on field surveying and indoor analysing,dealing with principal problems of the classification in Lou soil at present,the paper disscussed the effect of anthropogenic activity on the soil weathering and development. Because of artificial tilth cultivation and fertility processing,Lou soil has formed immense thick artifical mulch and argic horizon, produced twice recalcic evidence, soil weathering development is situates in desalting siallitic stage with childhood characters. Therefore,Lou soil can be serverd as foundation and criterion for soil grouping. That is,if the thickness of artifical mulch is over 50 cm,it should be serve as a new soil group from original soil type,and should be classified alone,otherwise,it should belong to the original soil group-cinnamon soil. |
