In order to reveal the further influence mechanism and law of intermittent infiltration of surge irrigation,based on the theory of Green-Ampt and Philip models, this paper proposes the concept of dividing the infiltration and wetting zone of the second water supply period and later period of water supply into two zones. The two zones were humid region of gravity potential and matrix potential. And the infiltration of concept characteristics of two zones was described. Building a mathematical model of the increasing capacity of volumetric water content by the inner relationship between the parameters of the two models (Green-Ampt and Philip models) and based on the linear pattern characteristics between the increment of soil volumetric water content and cumulative infiltration capacity, the water movement parameters of different water supply periods were determined. One of the water movement parameters was suction value of wetting flog hf and another was characterized saturated hydraulic conductivity Ks. The value of hf of intermittent period has the decreasing trend with the increase of the number of cycles. Finally, using the improved model to compare the calculated cumulative infiltration capacity and wetting front with measured data, a higher fitting precision was acquired. Compared with the measured data, the overall average relative deviations were 3.6% and 8.6% respectively. The improved model has good applicability. Hence a more accurate description of the mechanism of intermittent infiltration of surge irrigation could be described by this model which provides theoretical basis for the reasonable design of surge flow irrigation technology.
