The invention is a multi-spectral stealth skin and an adaptive camouflage system, wherein the multi-spectral stealth skin comprises a low infrared emission layer, a microwave absorption layer and a heating layer connected in sequence from top to bottom, wherein the microwave absorption layer comprises a visible light stealth layer, and the visible light stealth layer is an environmental mimicry film prepared by injection molding of thermochromic capsules and polydimethylsiloxane. The application comprises applying the multi-spectral stealth skin to an environmentally adaptive multi-spectral compatible stealth skin system, wherein the adaptive camouflage system comprises: an environmental recognition unit, a control system unit and a multi-spectral stealth skin. The multi-spectral stealth skin and the adaptive camouflage system of the present invention have strong radar-infrared stealth and environmentally adaptive visible light stealth capabilities, and have high commercial value and promotion value.
