The invention relates to a floor system and belongs to the technical field of wood-plastic floors and accessories thereof. The floor system comprises wood-plastic floors and a base, wherein tenons are arranged at the lower layer of each wood-plastic floor downwards, a first clamping action part is arranged at the side end, close to the outer side of each floor, of each tenon, and a second clamping action part is arranged at the other side end of each tenon; a base body and mortises are arranged on the base, the mortises are matched with the tenons, each mortise is provided with a first clamp and a second clamp, and the first clamp and the second clamp are respectively matched with the first clamping action part and the second clamping action part; clamping directions of the first clamp and the second clamp are opposite. According to the floor system, pavement is realized by creatively utilizing the mortises and the tenons which are matched with each other and positioned between the floors and the base, so that the labor cost is largely reduced, the mounting efficiency is improved, and the risk of structural damage is reduced; during mounting, as long as a labor treads the floors by feet to clamp the floors and the base, the pavement is realized, so that the mounting is convenient, and the mounting fun is increased.
