摘　　要：为研究大径级大花序桉人工林的基本木材性质,采用排水法对35年生大花序桉人工林木材的生材密度、基本密度、树皮率、心材率以及生材含水率等指标进行了测试。结果表明:35年生大花序桉的树皮体积百分率为8.92%,树皮质量百分率为12.35%,生材密度为1.12g·cm^-3,基本密度为0.76g·cm^-3,生材含水率为44.79%。各部位含水率差别不大,各指标表现都很好。in order to study the basic wood properties of Eucalyptus cloezianaplantation,the wood density,basic density,bark rate,heartwood rate and moisture content of 35 years old Eucalyptus cloeziana plantations were measured by drainage method.The results showed that the bark volume percentage of 35 years old Eucalyptus cloeziana was 8.92%,the bark mass percentage was 12.35%,the basic density of raw wood was 1.12 g cm^-3,the basic density of raw wood was 0.76 g cm^-3,the moisture content of raw wood was 44.79%.
