摘      要：Salt (NaCl) solution was applied to the surface of a cultivated field with 3 × 6 m2 and then was leached downward by a steady infiltration rate 4 mm/d. Sampling programs were designed under guiding of Dagan s scale concept. Each soil sample had eight replicates. Salt concentration exhibited a much more variability in both vertical and horizontal directions than water content, especially in the zones of peak values of concentration. The volume of immobile water, which might play an important role in the variability of concentration, was in the range of 24-39% of the total water volume in the experimental studies.
