Provided in the present disclosure are a core flooring layer of a light-foamed SPC floor and a light-foamed SPC floor. Based on the total weight of the core flooring, the core flooring of the present disclosure contains 65.0˜75.0 wt % of calcium carbonate, 18.0˜25.0 wt % of polyvinyl chloride resin, 2.2˜3.0 wt % of a foaming regulator, 2.5˜3.3 wt % of a stabilizer, 0.10˜0.20 wt % of a plasticizer, 0.10˜0.15 wt % of an external lubricant, 0.1˜0.40 wt % of an ADC foaming agent, and 0.5˜1.0 wt % of an NC foaming agent. The present disclosure can greatly reduce the density of a SPC floor while improving the static bending strength, flexural elastic modulus and peeling strength, and reducing heating warpage.
