Claim:
A method for manufacturing artificial paving that helps improving global warming, mainly constituted by an ecological gradation layer and a water permeable paving layer, characterized in that: after ground leveling, an ecological gradation layer is laid first, wherein the ecological gradation layer is formed of gradation materials for road construction or on-site earth, hollow bodies being mixed in the earth, each of the hollow bodies comprising a shell composed of two halved shell members jointed to each other to define therebetween an interior space, the shell members forming through apertures communicating with the interior space, the hollow bodies and the gradation earth being mixed and laid and then subjected to pressurization for ramming; and a water permeable paving layer set on the ecological gradation; whereby rainwater falling on ground is allowed to effectively permeate the artificially set layers to reach an underground water stratum that is located under an underground soil stratum, so that rainwater is conducted to deep location of ground to supplement the underground water stratum, and the interior space defined between the shell members of each of the hollow bodies contained in the ecological gradation layer provide an excellent survival environment for microorganisms and protozoa inhabiting in earth.
