Water transportation between soil and groundwater in soda saline soil system in summer

Based on in-situ observation, transportation feature of a saline soil system among atmosphere, soil water and groundwater was analyzed. The main constrain of soil water transportation was the pattern of micro relief, resulting in special transform model of groundwater-soil water-atmosphere water. Enrichment of soil moisture at the micro-slope (sodic saline soil) was not significant. Surface runoff is the key procedure of soil transportation. Micro basin (saline meadow soil) became channel of surface runoff and groundwater, where vast water transported in vertical direction into groundwater. Vensim software was applied to simulate the transform process between groundwater, soil water and atmosphere. The simulation result is in agreement with observed value.
