Bamboo as an important biological resource has become an alternative to wood gradually,but the variation in mechanical properties leads to difficulty in its use to some extent.So deep understanding of the nature in bamboo is needed to satisfy the utilization effectively.As we have known,the density is one of mechanical properties of bamboo.Therefore,this paper studied the variation in bamboo density with the weighing method.The results showed that the density decreases gradually from the outer to the inner of bamboo,especial in 1/3 of the wall away from the outer to the inner of bamboo. With the age increasing,the density also has a corresponding increase trend,and at the age of 6,it reaches the maximum.Besides,it increases gradually with bamboo stalk rising.Through variance analysis and multiple comparisons of the various influencing factors,the site,age and height all affect the density significantly.
