Abstract: In order to study the current soil salinization characteristics in the Huanghebei mining area, field survey in situ sampling and indoor testing were adopted to study the soil salinity content, spatial distribution, vertical variation and the correlation between shallow groundwater and soil salinization. The results show that the soil is mainly composed of potential saline soil and slightly saline soil, the anions in the soil are mainly bicarbonate and sulfate ions, and the cations are mainly sodium and calcium ions. Soil shows surface aggregation vertically, surface salinization is serious, salinization degree is reduced in the deep. There is an inherent natural direct relationship between the saline soil and the shallow groundwater. The total salt content in the soil is obviously positively correlated with the total dissolved solid content in the groundwater, while it is negatively correlated with the depth of the shallow groundwater level. The development and utilization of coal mining in the study area will aggravate the degree of soil salinization and the coal mining needs to be reasonably determined according to the degree of surface collapse, so as to reducing the degree of soil salinization.
