The temporal and spatial distribution of SMP in tomato root zone and the correlation between tomato evaportranspiration and SMP variations were analyzed. The results showed that the variation of SMP among the soil profiles of 0, 15 and 30 cm from drip tape was insignificant, and the horizontal distance of tensiometers to drip tape had little effect on the correlation between tomato ETa and SMP variations. Lateral depths significantly influenced SMP from 20 to 70 cm soil layer and there were obvious effects of tensiometer depth on the correlation between tomato ETa and SMP variations.
