Abstract:
The biomass and primary production of a natural Fargesia scabrida forest were determined based upon the regression models obtained by measuring the average basal diameter (D), density (N), plant height (H), and the dry weights of stems(Ws), branches(WB), leaves(WL) and rhizomes(WR) of Fargesia scabrida plants in the sampling quadrats. The regression models are as follows:
Ws=160.942+0.227(D2NH) p<0.001
WB=76.008+0.039(D2NH) p<0.001
WL=80.643+0.051(D2NH) p<0.001
WR=285.554+0.074(D2NH) p<0.001
By using these models, we calculated that the biomasses of stems, branches, leaves and rhizomes were 7.558 t/ha., 1.782 t/ha., 2.143 t/ha. and 4.795 t/ha., respectively. The total biomass was 16.278 t/ha. The net primary production was estimated to be 3.256 t/ha./yr.
