为了进一步研究宁夏半干旱黄土丘陵区土壤结构退化的机理，以宁夏半干旱黄土丘陵区彭阳中庄典型小流域为研究区，选取16个不同的立地类型，包括不同坡度、不同坡位、不同措施、不同年限等，采用实地调查和土壤采样分析相结合的方法，从土壤容重、土壤团聚体、土壤持水量及孔隙度等方面对土壤的退化特征进行了分析。结果表明：不同立地类型的土壤结构均有不同程度的退化，为该区域生态综合治理提供了理论依据。

In order to further study the mechanism of soil structure degradation in Ningxia semi -arid loess hilly region, the au-thor took the typical small watershed Pengyangzhongzhuang in Ningxia semi -arid loess hilly region as the studied region , selected 16 different site types (including different gradients, different slope positions, different measures, and different years), and ana-lyzed the characteristics of soil degradation from the aspects of soil bulk density , soil aggregate, soil moisture content, soil porosity and so on by using the methods of field investigation and soil sampling analysis .The results showed that the soil structure of different site types all had different degrees of degradation , which could provide a theoretical basis for the ecological management of this re -gion.
