The variation of green density and bark percentage wasstudied in this *** green density was tested by excluding water, and bark percentage was tested by measuring bulk and weighing quality. The research showed that: the green density of fast-growing eucalyptus of five year, six year, seven year was 1.033g/cm3, 1.037 g/cm3,1.036 g/cm3 respectively, and their variation was unremarkable among different age. The bark bulk percentage of five year, six year, seven year was 17.56%、16.29%、13.94% respectively, and their variation wassignificant among different age. The bark quality percentage of five year, six year, seven year was 18.34%、 14.57%、11.21% respectively, and their variation wassignificant among different age.
