The invention provides a solar heat supply type carpet. A solar thermal collector is connected with a heat radiating tube; the heat radiating tube is positioned between a bottom material and a temperature-sensing color-changing surface material; the temperature-sensing color-changing surface material includes four layers which are respectively a first temperature-sensing color-changing layer, a second temperature-sensing color-changing layer, a third temperature-sensing color-changing layer and a fourth temperature-sensing color-changing layer from inside to outside; the first temperature-sensing color-changing layer, the second temperature-sensing color-changing layer, the third temperature-sensing color-changing layer and the fourth temperature-sensing color-changing layer are all transparent when no heat is supplied; the upper surface of the temperature-sensing color-changing surface material is covered with a layer of plush surface. The solar heat supply type carpet is capable of automatically changing the color of the carpet according to changes of heat in order to make people have a good mood.
