Abstract: The changes of cellulose content and lignin content and fiber morphology were studied for Neosinocalamus affinis and Dendrocalamus farinosus with the typical thick-growing characteristics from the different regions in Sichuan province. The results showed that the cellulose content and lignin content were significantly different between the different species in the same region. The cellulose and lignin content, the length and width of fiber and their aspect ratio within the same specie of bamboo in the different regions were related to the different regions and the age of bamboos. Taking account of good fiber material of bamboo for paper making, N.affinis(cellulose content is about 45%, lignin content is below 28%)and D.farinosus(cellulose content is over 50%, lignin content is below 20%)from Zhuhai region are suitable for pulp making.

Key words: Neosinocalamus affinis, Dendrocalamus farinosus, cellulose, lignin
