Abstract

To determine a rule for interannual variation characteristics in non-spatial, structural stands of new moso bamboo （Phyllostachys edulis） based on carbon sink （1－5 a）. An 80 m 100 m fixed plot was established at a long-term, afforestation, fixed observation research site for carbon sequestration. Linear regression and correlation were used for the analysis. Results showed that 1） stand density, DBH, and culm height were the dominating factors for interannual component changes, and these increased with bamboo age. 2） In the young stand, stand density （N） increased with stand year （y） with a fitted regression equation of: N=17.214y2+309.21y－ 217.4, R2=0.981 1. 3） The allometric equation for mean DBH and stand year （y） fitted with linear regression was DBH=0.015 7y2+0.727 9y+1.598 0, R2=0.756 5 The linear regression for the relationship between culm height （H） and stand year （y） was projected to be H=0.108 5y2+0.429 9y+2.155 3, R2=0.723 2. Therefore, in the young moso bamboo stand, stand density, DBH, and culm height all had a positive relationship with age. ［Ch, 4 fig. 8 tab. 20 ref.］
