Abstract: For an accurate assessment of forest biomass in Zhejiang Province,forest vegetation biomass was calculated at the plot level based on 2009 forest inventory data. Each plot was regarded as a basic unit with biomass calculated using the single tree biomass model and the biomass per unit area model with biomass per unit area methodology. Systematic sampling was utilized to estimate the overall provincial forest vegetation biomass with estimating accuracy and sampling range of assessment provided. Results for Zhejiang Province in 2009 showed a total forest vegetation biomass of 37 010.7 104 t. Within the major forest vegetation types,the arbor community was 29 096.3 104 t,the bamboo community was 3 763.0 104 t,and the shrub community was 1 748.0 104 t. Using a guaranteed reliability of P < 0.05,accuracy for total forest biomass was 96.64% with a sampling interval of 35 767.1 104 - 38 254.3 104 t;accuracy for the arbor community was 95.58% with a sampling interval of 27 810.2 104 - 30 382.3 104 t;accuracy for the bamboo forest community was 89.13% with a sampling interval of 3 353.9 104 - 4 172.0 104 t;and accuracy for the shrub community was 90.00% with a sampling interval of 1 573.2 104 - 1 922.7 104 t. Therefore,using these methods a high precision for forest vegetation biomass assessment was attained.[Ch,3 tab. 26 ref.]
