Embodiment
[0024] This embodiment is a method for calculating the critical groundwater burial depth of soil salinization. The principle of the method is as follows:
[0025] Under certain conditions of the soil layer medium, groundwater brings salt to the surface through capillary force to form salinization. The key to causing salinization is the maximum height of groundwater capillary rise, which is the key problem causing salinization.
[0026] In the case of a certain soil medium, groundwater will have a rising process along the soil void under the capillary force. This process is closely related to the problem of soil medium and soil water. The soil water temperature will also affect the maximum rise height of capillary water. When the groundwater level is too shallow, the groundwater will come into contact with the surface under capillary action, bringing the salt to the surface to form accumulations. When the groundwater level is too high, even if there is a certain distance betwe...
