摘要

The purpose of this study was to determine the carbon storage of China-fir (Cunninghamia lanceolata) trees. The China-fir plantation of the study area was located in central Taiwan, in compartment no. 111, Pa-Hsien-Sha working circle, and Shyr-Wen-Shi demonstration zone. Data were collected from 16 sample trees of this China-fir plantation. Two-way ANOVA was used to analyze carbon concentrations by diameter classes and parts (foliage, branches, and stems) of trees. Mathematical functions were applied to estimate the relationships between the aboveground carbon storage of trees and other variables. The following results were obtained. (1) Carbon concentrations in various diameter classes and parts of trees significantly differed. In each diameter class, carbon concentrations were in the order of foliage＞branches＞stems; carbon concentrations of branches and stems respectively increased with diameter classes. (2) Mathematical functions were established to estimate the aboveground carbon storage of foliage, branches, stems and trees by dbh. (3) The coefficient for translating tree volume into aboveground carbon storage of trees was 190.4 kg m^(-3).
