Abstract: The biomass dynamics of Cryptomeria japonica (L.F)D.Don was studied by the use of Richards model·The stand biomass (W,t/hm2)can be calculated by the followingfunctions, W=318.0349 (1-e-O.1414sst)1/1-0.664835,where t is the sand age in years. The result showed that the growth process of Cryptomeria japonica to 16 years can be divided into three stages:1 to 5—year is young growth stage:5—10th year is pole stage;after 10th year will be submature stage.The calculating result is that the maxi-mum biomass will amount to 318.Ot/hm2
