土壤系统分类的基层分类中土系的研究——以南京东郊典型样区为例

Soil series in basic categories of soil taxonomy — A case study in eastern suburbs of Nanjing

以成土母质类型、土体构型和特征土层的主要性态指标作为土系划分的依据，采用性态检索次序和地名加表下层质地的土系命名法，将南京东郊典型样区划分为１４个土系。此外，还对土壤基层分类基础成果的应用进行了初步探讨。

The authors selected parent materials, soil profile patterns and the principal features of soil horizon as the criteria for soil series identification. The nomenclature of soil series is the combination of the local name and dominant texture of subsurface soil. In total, 14 series were identified in the eastern suburbs of Nanjing. In addition, the application of the research results are discussed.
