Abstract
To develop accurate and predictive global carbon cycle models, it is important to understand the change of accumulated carbon for many ecosystems according to successional stage. In this study, I measured total biomass, litter and soil organic matter contents through an aerial photo and field observation. As a result, accumulated organic matter contents per unit area (kg $m^{-2})$ of three communities composed at grassland were 7.00 kg $m^{-2}$, in Solidago altissima community, 9.18 kg $m^{-2}$, in Imperata cylindrica community, and 12.68 kg $m^{-2}$, in Miscanthus sinensis community, respectively. Accumulated total organic matter contents was high in Miscanthus sinensis community at later succession stage but soil carbon was low. In Miscanthus sinensis community, highly accumulated organic matter contents was resulted from increasing of biomass comparison with that of the other two communities. The pattern of accumulated organic matter contents was changed by changing of the dominant community due to progressing in succession. The accumulated carbon in temperate grassland will be increased with progressing in succession.
