Land use, soil organic carbon content and bulk density are important factors influencing the occurrence of soil water repellency (SWR) and water flow through the soil profile. This study elucidated the relations between the repellency index (RI) and contents of soil organic carbon (SOC), organic-complexed aluminium (Al_p) and iron (Fe_p), pH, specific surface area (SSA) and bulk density in the ortstein horizon and the overlying and underlying horizons in two podzolic soils under grassland and forest. The soil under grassland was originally used as a cropland. The RI was quantified from the ethanol/water sorptivity ratio. The results showed that the RI in the ortstein horizon (20.6–27.3) in the air-dried state in both soils was many times greater than in the overlying (7.2–19.0) and underlying (6.1–11.5) horizons, whereas in moist conditions (from soil water content at sampling and air-dried state), all horizons were not repellent. The RI in the air-dried soil in the overlying horizon was higher under grassland than forest, whereas the inverse was true in both the ortstein and underlying horizons. SOC, organic-complexed Al_p and Fe_p contents, and SSA were the highest in the ortstein horizons. The pH value increased from 5.3 in the overlying horizon to 6.0 in the underlying horizon in the grassland soil. The corresponding values in the forest soil were 4.2 and 5.0. The RI values in the dry condition were significantly correlated with Al_p (R² = 0.976), Fe_p (R² = 0.798), SSA (R² = 0.724), and SOC (R² = 0.638). The study provides new information about the vertical distribution of soil water repellency in ortsteinic soils depending on the soil water status and the type of land use. The potential mechanisms of the distribution of SWR are discussed.

土地利用、土壤有机碳含量和容重是影响土壤拒水性 (SWR) 和水流通过土壤剖面的重要因素。本研究阐明了排斥指数（RI）与土壤有机碳（SOC）、有机复合铝（Al _p）和铁（Fe _p）含量之间的关系。)、pH、比表面积 (SSA) 和 ortstein 层位以及草地和森林下两种灰化土壤的上覆层和下层层的容重。草原下的土壤最初用作农田。RI 由乙醇/水的吸着率比值量化。结果表明，两种土壤在风干状态下的奥特斯坦层 (20.6-27.3) 的 RI 比上覆 (7.2-19.0) 和下伏 (6.1-11.5) 层高许多倍，而在潮湿条件下（从取样时和风干状态下的土壤含水量），所有地层都没有排斥性。草地下上覆层风干土壤中的 RI 高于森林下，而在 ortstein 和下伏层中则相反。SOC，有机络合的 Al _p和 Fe_p含量和 SSA 在 ortstein 视野中最高。草地土壤pH值从上覆层的5.3上升到下层层的6.0。森林土壤中的相应值为 4.2 和 5.0。干燥条件下的 RI 值与 Al _p (R ² = 0.976)、Fe _p (R ² = 0.798)、SSA (R ² = 0.724) 和 SOC (R ² = 0.638) 显着相关。该研究根据土壤水分状况和土地利用类型提供了有关奥斯坦尼克土壤中土壤疏水性垂直分布的新信息。讨论了 SWR 分布的潜在机制。
