    摘要:

    黄土高原塿土在《中国土壤系统分类(修订方案)》中属土垫旱耕人为土类的相应亚类,其土壤水分状况是诊断表层所属人为表层类堆垫表层(覆盖层)和诊断表下层(黏化层)的重要诊断特征。以土壤持水性能、蒸发性能和水分移动性能为切入点,对塿土覆盖层和黏化层的土壤水文效应进行研究论证,以期对土垫旱耕人为土类及其亚类的诊断层与诊断特征获取更深层的认识.

    Abstract:

    Lou soil (a well developed agricultural soil) in Loess Plateau can be sorted as a subgroup under the eumorthic anthrosois in the Chinese Soil Taxonomy (Revised Proposal). Soil moisture regime is an important diagnostic characteristic of the anthropic cumulic epipedons (the earth-cumulic surface horizon) and the sub-surface horizon (the argic horizon) of the diagnostic surface horizon. With soil retention capability, evaporation capability and soil water movability as starting point, soil hydrologic effect of the earth-cumulic surface horizon and the argic horizon of Lou soil is discussed in this paper.
