The study on soil-water is important for farm, conservancy, hydrogeology and environment. This paper introduced the method and equipment for getting soil water in carrying out the project named study on the moisture movement in unsaturated zone in the Yellow River delta. The variation and influence factor of soil-water mineral degree is analyzed by using the assaying result of water sample. The follow are the main conclusions: In shallow groundwater areas, the variation of soil water is connected with groundwater; the effect of evaporation and transpiration on soil water are different. The evaporation increases mineral degree of up layer soil water, the vegetation decreases the mineral degree when they are growing; groundwater, vegetation and the character of soil is the important influence factor of soil-water mineral degree in shallow groundwater areas.
