Abstract

Soil salinization in coastal areas is closely related to the capillary rise of groundwater. However, the water-salt distribution pattern due to capillary rise in soils with different salinization types is not clear. Through indoor soil column experiments, the capillary rise process in typical coastal saline soils in China was analyzed, and the effects of different salinization types on the height of capillary rise, water content and salt content were studied. The results showed that the largest capillary rise height was found in Cl--SO42- type saline soils, followed by Cl- type, SO42--Cl-, and the smallest capillary rise height was found in SO42- type saline soils; saline soils were prone to salt accumulation at 50 - 70 cm above the diving surface under the effect of capillary rise, and the salt accumulation effect was more significant in the Cl--SO42- type and the SO42--Cl- type saline soils; The water content of different types of saline soils was similar within 60 cm above the diving surface, while the water content of the soil at the top of capillary action was in the order of Cl--SO42- type > SO42--Cl- type > Cl- type > SO42- type. The results of the study may provide a theoretical basis for the law of capillary rise in saline soils.
