The bamboo-based composite sheet (BCS) based on sustainable theory was designed to improve the utilization of bamboo waste as well as provide a green and renewable product in the surface decoration field. The influence of color, width, proportion for BCS was studied to develop a preparation technology. The perception evaluation (aesthetic value and emotional characteristics) of BCS was analyzed. These results showed when the bamboo proportion was at a low level (10%), the perception evaluation of BCS was almost unaffected by the color and width of bamboo waste. As the bamboo proportion increased constantly, BSC gave a stronger feeling of lively, traditional and warm. The BCS with thin bamboo waste gave a sense of clean and regularity. On the contrary, the BCS with thick bamboo waste was more suitable for creating a dynamic and radical environment. The BCS with yellow bamboo waste gave a feeling of exquisite, modern, and warm, while green bamboo waste gave a sense of unordered, robust, traditional, and cold.
