| 摘 要： | 本文根据样方上测定糙花箭竹的地径、茎高、密度、茎重、枝条重、叶重和鞭系重资料，研究竹林生物量和生产力，并建立回归数学模型为：茎重Ws=160.942+0.227(D2NH) p<0.001 枝条重WB=76.008+0.039(D2NH) p<0.001 叶重WL＝80.643+0.051(D2NH) p<0.001 鞭系重WR=285.554+0.074(D2NH) p<0.001由方程估测出天然糙花箭竹林的各器官干重分别为茎7.558，枝条1.782，叶2.143，鞭系4.795t／ha。总生物量为16.278t／ha，平均净生产量为3.256t／ha。

| 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(W_s), branches(W_b), leaves(W_L) and rhizomes(W_R) of Fargesia sca- brida plants in the sampling quadrats. The regression models are as follows: W_s=160.942+0.227(D~2NH) P<0.001 W_B=76.008+0.039(D~2NH) P<0.001 W_L=80.643+0.051(D~2NH) P<0.001 W_R=285.554+0.074(D~2NH) P<0.001 By using these models, we calculated that the biomasses of stems, branc- bes, leaves and rhizomes were 7.558t/ha., 1.782t/ha., 2.143t/ha. and 4.795 t/ha., respectively. The total biomass was 16.278t/ha. The net primary pro- duction was estimated to be 3.256t/ha. /yr. |
