The invention discloses a novel warp-knitted spliced square carpet and a continuous production method thereof. The carpet structurally comprises a surface layer, a polyolefin hot melt adhesive layer, a bottom layer, a strip-shaped pressure-sensitive adhesive layer and a release film from top to bottom. The surface layer adopts 100% polyester (PET) as a surface layer raw material, has higher strength and wear resistance and is more suitable for the field of commercial offices, and the 100% polyester felt is adopted as the bottom layer, so that the surface layer has good rebound resilience and an excellent sound insulation effect. The material has excellent wear resistance, and is free of damage in 3000 circles under the load of 90kg in a wheelchair test; the upper surface of the carpet surface is subjected to special surface treatment, good waterproof and antifouling effects can be achieved, water drops are completely spherical when dropping on the carpet surface, and the carpet cannot be wetted or immersed in
