The heat transport in the plasma edge region is investigated based on the transition transport model with hysteresis nature. For a given in flux from the upstream side, the heat transport equation is solved numerically. The time evolution and the burst characteristics of the heat transport are analyzed. Especially, the parameter dependences of the amplitude and the frequency of the out flux burst are examined. The critical behavior of the transition between two transport mechanisms, i.e., the hysteresis type and the discontinuous one, is expressed as power law relations of them.
