Chemical composition, morphological properties and papermaking properties of Sasa quelpaertensis Nakai were investigated in order to use it comprehensively. The lignin contents of stalks and leaves were 18.8% and 15.3% and the holocellulose contents were 63.3% and 48.6% respectively. The contents of ash and the amount of water extract showed the higher value than those of wood or other bamboo species. The average fibers length and width of Sasa quelpaertensis Nakai were 780 ${mu}m$ and 14.8 ${mu}m$. The fibers of Sasa quelpaertensis Nakai stalk had thinner width and more slender structure than those of softwood. The handsheet made of Sasa quelpaertensis Nakai alkaline pulp showed higher in tensile strength and bulkier structure than those of handsheet made of soft wood unbleached kraft pulp.
