[Objective] To investigate the potential salinization of soil in Quzhou County, Hebei Province in recent years, in order to provide scientific basis for preventing soil salinization.[Methods] The brackish water irrigation experiment, soil profile observation and soil sample analysis was conducted to study the soil salinity transport and its potential salinization to the soil in Heilonggang basin from the aspects of altitude, soil depth, groundwater depth and soil texture.[Results] Rainfall and brackish water increased the possibility of surface salt leaching to the lower layer, which leads to the accumulation of soil salinity in 40-100 cm soil layer. Soil with more sticky texture appeared at 56 cm depth, which prevented the movement of soil salt and accumulated on it, thus creating potential conditions for soil salinization. Micro-topography affected the redistribution of salinity, and soil salinity content and altitude showed a good correlation (R²=0.76). The change of texture types in the soil layers at different depths affected the redistribution of soil salinity. The phenomenon of surface aggregation of HCO₃^- was obvious. The contents of SO₄^2- and Ca²⁺ in all soils were significantly correlated with total salt content (0.88^*~1.00^**, 0.89^*~0.97^**), and there was a significant relationship between the contents of SO₄^2- and Ca²⁺ (0.86^*~0.97^**).[Conclusion] The change of micro-geomorphology and soil profile pattern will affect the redistribution of soil salinity, and have an important impact on the potential salinization of soil.
