Environment protective liner plank structure having several legs and a panel. Each leg is composed of multiple layers of rice grasses (or wheat stems) which evenly overlap each other in the same direction. A layer of adhesive is sprayed between each two layers of rice grasses (or wheat stems). When each layer of rice grasses (or wheat stems) is evenly overlaid on a lower layer of rice grasses (or wheat stems), a male mold is used to compress the rice grasses (or wheat stems) into a compact state. The lowermost layer of rice grasses (or wheat stems) of the panel is evenly overlaid on the adhesive on the uppermost layer of rice grasses (or wheat stems) of the leg. A plane board mold is used to compress the rice grasses (or wheat stems) into a compact state. A layer of adhesive is sprayed over the lowermost layer of rice grasses (or wheat stems) of the panel and then an upper layer of rice grasses (or wheat stems) are overlaid on the lowermost layer of rice grasses (or wheat stems). Then, the plane board mold is used to compress the layer of rice grasses (or wheat stems). Such procedure is repeated until the panel of the rice grasses (or wheat stems) has a certain thickness.
