Abstract:: The study on soil water content in apple orchard in the highland region of the Loess Plateau showed that within the 600 cm profile, the variation of soil water could be divided into two periods which were water increased in winter and decreased in summer. With the increase of the depth of soil profile, the water content reduced and tended to be stable. The water content in winter was not only more than that in summer, but also well distributed in the soil profile. However, in summer season the soil water mainly concentrated on the upper layer. Based on the standard deviation and variation coefficient, soil water change in the profile could be divided into four layers: quickly changing layer, relative stable changing layer, slow changing layer and less changing layer.
