摘　　要：对生长于湖北长岭岗林场陡坡地及平缓地两种立地条件的12年生日本落叶松林的木材密度进行了测定,通过差异显著性分析,结果为:两种立地条件下日本落叶松幼龄材的基本密度、气干密度和全干密度,在α=0 05水平下差异均不显著,其木材的基本密度为0 443g/cm3,变异系数为2 22%;气干密度为0 537g/cm3,变异系数为1 71%;全干密度为0 502g/cm3,变异系数为1 79%。The wood density of 12 years old Larix kaempferi stands in steep slope and flat land of Changlinggang forest farm of Hubei province was determined. The results showed that there was no significant difference of wood basic density, air density and dry density between two different site conditions at α= 0.05 evel. The basic density, air density and dry density of wood were 0.443 g/cm^(3), 0.537 g/cm^(3) and 0.502 g/cm^(3) respectively, with the variation coefficient of 2.22 %, 1.71 % and 1.79 % respectively.
