Carbon cycling in Moso bamboo forests

抄録

Moso bamboo forests have been assumed to show a high carbon sequestration ability. On the other hand, whole carbon cycling studies covering their biennial growth are still rare. The aim of the study was to clarify the NPP and NEP in a Moso bamboo forest in Taiwan by considering above- and below-ground processes over a 4-year experimental period. The estimated NPP and NEP showed considerable inter-annual variations (coefficient of variation of 39 and 79%, respectively) in this study. The mean NPP and NEP were 8.8 and 4.3 Mg C/ha/year, respectively. A global comparison of NPP and NEP among forest ecosystems using data from published literature indicated that the estimated NPP and NEP in the present study were within the upper range of the values reported for other world-wide forest ecosystems regardless of the small Moso bamboo biomass.
