本文对安徽、河南和湖北等地７个有代表性的土壤剖面进行研究。结果表明，土壤的颗粒组成继承了成土母质黄土的特性；土壤表层和漂白层与粘淀层相比，基本性质存在明显的不同
In this paper, seven representative soil profiles in Anhui, Henan and Hubei are studied. The results show that the soil particle composition inherits the characteristics of soil-forming parent loess. The basic properties of soil surface and bleaching layer are obviously different from those of the adherent layer
