Abstract The essential of decreasing temperature by reformative soil in cold regions is the change of the transfer mechanism of reformative soil layer through changing the structure of soil. According to mechanism of heat transfer in porous media，the minimum reformative soil thickness that is needed to form heat convection in the soil layer is induced by analysis of natural convection heat transfer in reformative soil. The results can provide references to the application of reformative soil to engineering projects in cold regions.
