Abstract: The present disclosure discloses a wood-bamboo double layer floor including a top panel and bottom panel. The top panel is long strip shape and made by the whole log. The bottom panel is made by the whole log. Wood fiber directions of the top panel are parallel to a long side of the floor. Wood fiber directions of the bottom panel are parallel or perpendicular to the long side. The top panel and bottom panel are adhered by adhesive. Patchwork opens are pieced up to each other and made around the bottom panel. Grooves are defined in the bottom panel and arranged in a row along a direction being perpendicular to the wood fiber directions of the bottom panel. bamboo strips embedded and adhered in the grooves, are matched with the grooves. And bamboo fiber directions are the same as length directions of the bamboo strips.
