Provided is a method for manufacturing artificial paving that helps improving global warming. A water permeable paving layer is provided under which a drain layer, which includes gravels or sand, is selectively formed, and an interfacing layer is formed under the drain layer. An ecological gradation layer is set and rammed. The underside ecological gradation layer provides an effect of supporting and, due to the ecological gradation layer containing therein hollow bodies, which can be embodied as disaster-prevention water-storage hollow bodies or earth-improvement hollow bodies or microorganism-culture hollow bodies or water-keeping hollow bodies as desired, allows rainwater falling on ground surface to quickly penetrate down into the underground location, makes the ecological gradation layer effectively preserve water in high water content, and prompt breeding of microorganisms, whereby when the atmosphere is of a high temperature, underground humidity can be released through drainpipes that constitute the water permeable paving.
