Abstract：Investigating the influence of environmental factors on soil water and salt transport is crucial for the scientific improvement and efficient utilization of saline-alkali land.This study used numerical calculations to explore the effects of different irrigation-evaporation ratios and groundwater salinity on soil water and salt transport.The results showed that:different irrigation-evaporation ratio treatments had little effect on deep soil moisture content;the smaller the irrigation-evaporation ratio and the higher the groundwater salinity,the more significant the accumulation of salt in the soil profile.When the groundwater salinity increased from 1 g/L to 10 g/L,the maximum salt content increased from 12.20 g/kg to 67.60 g/kg.The cumulative salt content of each soil layer decreased with increasing depth,and the higher the irrigation-evaporation ratio and the lower the groundwater salinity,the less the cumulative salt content in the soil.
