本文论述了土壤形成过程中应具有的一些质的特征,从而证明了流动砂丘并非属于土壤,而只是地质作用的非土形成物或成土母质。在此基础上,对流动砂丘上土壤的形成发育演变方向以及在土壤分类中的地位和命名等问题进行了探讨。

From the viewpoint of soil genesis,some natures existing in the process of soil formation are discussed after expounding the important functions of organisms, especially plants in the process of soil formation, development and evolution. Thus it is proved that mobile sand dunes are only non-soil materials affected, by geological function or parent materials, but not soils. Onthe basis of above analysis, the formation, development and evolution direction of the soil on mobile sand dunes and its position and naming in soil classification are approached.
